Selecting the correct sample system is one of those decisions that looks simple until it goes wrong.
Your refinery needs a heated sampling system for vacuum tower bottoms at 600°F with C276 construction. The system must integrate with your existing piping configuration and meet your facility’s emissions requirements.
SENSOR Sampling Systems engineers the exact system you need. We work directly with you, providing custom drawings and expert consultation to ensure the system fits your application.
No compromises. No field modifications. Equipment designed specifically for your process.
The Problem with One-Size-Fits-All
Standard sampling systems rarely match real-world applications. For example, a bottle system designed for diesel at 80°F fails when sampling propane at 200 psig. Process conditions vary too much for generic solutions. The gap between what a standard system handles and what your process demands is where failures happen.
Your application requires equipment engineered for your specific process conditions, material properties, and site requirements. When you use generic solutions, real problems follow. Wrong materials corrode. Inadequate pressure ratings fail. Missing safety features can violate regulations. Poor integration forces expensive field modifications.
SENSOR Sampling Systems takes a different approach. We engineer solutions for your exact requirements through custom drawings and direct expert consultation.
How We Engineer Solutions That Fit
Here is what that Engineered-to-Order process looks like in practice:
1. Expert Consultation Process
Our sampling engineers work directly with you to understand your requirements. We discuss process conditions, material properties, site constraints, safety requirements, analytical methods, and installation environment. From there, we design systems that address all of these factors.
2. Custom Drawings
Every system starts with detailed engineering drawings, and you review them before we build anything. Dimensions, mounting details, connection points, material specifications, pressure ratings, temperature management features, and safety systems are all documented. You review and approve before fabrication begins. As a result, the system arrives matching your specifications exactly.
What does the custom drawing process actually look like? Custom drawings are central to our Engineered-to-Order approach. They ensure the system you receive matches your requirements exactly.
3. Decades of Application Experience
We have designed sampling systems for thousands of installations across refineries, chemical plants, and process industries. Over time, our engineers have learned which configurations work for specific applications and process conditions. That experience informs every design decision we make.
4. In-House Manufacturing
We control the entire production process. We engineer, build, test, and ship from our Houston, Texas facility. Because design intent translates directly to fabrication without communication gaps, quality is verified at every step.
5. Initial Consultation
Before any design work begins, our engineers ask questions that determine whether a system will work in your application.
- What media are you sampling?
- What are the operating and design process pressure and temperature?
- What is the vapor pressure at operating temperature?
- How much sample volume do you need?
- What are your site constraints?
- What safety requirements apply?
- What analytical methods will you use?
- What does your installation environment look like?
6. Design Development
With your requirements documented, the engineering work begins. Component selection is based on process conditions. Material specifications are chosen for chemical compatibility. Pressure ratings are set for safe operation. Temperature management maintains sample integrity and operator safety. Safety features address regulatory compliance. Integration details account for your installation.
7. Drawing Review
Once the design is complete, you receive detailed drawings showing the complete system. Overall dimensions and footprint. Mounting details and attachment points. Connection points with sizes and ratings. Material specifications for all components. Pressure and temperature ratings. Flow paths and valve locations. Safety features and their operation. Testing requirements. You review all of this before fabrication begins.
8. Revisions
As your project develops, changes are incorporated into the design. Additional site constraints. Modified process conditions. Updated safety requirements. Space limitations. Integration issues. Drawings are revised until they match your needs exactly.
9. Fabrication
Once you approve the drawings, production begins. The system is built to match the approved drawings precisely. Quality checks verify dimensions, materials, and functionality. Pressure testing confirms integrity. The system then ships ready for installation and operation.
The result is a process that eliminates surprises. You know exactly what you are receiving. The system arrives fitting your application. Installation proceeds without unexpected modifications. Startup happens without equipment issues.
Knowing the process matters, but selecting the right equipment type before design begins is where most mistakes get made.
Applications Engineering Gets It Right the First Time
Knowing the process matters, but selecting the right equipment type before design begins is where most mistakes get made.
Selecting the wrong sampling system wastes time and creates safety problems. When equipment does not match your application, it fails to deliver representative samples. Lab analysis suffers. Production decisions lack accurate data. Safety incidents occur. Regulatory violations accumulate.
Our applications engineers have worked on thousands of installations. Because of that experience, they know which solutions work and which create problems. They catch potential issues before equipment is ordered.
Standard Applications
For straightforward cases like naphtha at ambient temperature and low pressure, basic bottle sampling is the right answer. Engineering focuses on proper integration with your site requirements, mounting configuration, and connection details.
The more demanding your process conditions, the more that engineering experience matters.
Complex Applications
For high vapor pressure material at 400°F with corrosion concerns, the challenge is more involved. Multiple constraints from safety, emissions, and analytical requirements need evaluation. Our engineers design systems for:
- Extreme temperatures above 800°F or below -50°F
- Pressures above 3,000 psig
- Highly corrosive materials are attacking the standard 316 SS construction
- Toxic materials requiring closed-loop operation
- Materials that set up or crystallize
- Viscous materials resisting flow
- Multi-phase sampling requiring interface detection
- Confined spaces limit equipment size
- Hazardous areas requiring special certifications
In each case, engineering support prevents expensive mistakes. Custom drawings ensure the system fits your application before fabrication begins. Equipment arrives matching your requirements. Installation proceeds without modifications. Systems perform safely and reliably from day one.
Why Engineered-to-Order Matters
Process conditions at a Gulf Coast refinery handling vacuum residue look nothing like those at a Midwest chemical plant running light hydrocarbons. Site constraints change, safety requirements evolve, analytical methods advance, and installation environments present real challenges.
When you use generic equipment, you accept compromises. You adapt your process to the equipment instead of the other way around. Field modifications become necessary. Installation time increases. Performance suffers. Safety gaps appear.
Engineered-to-Order reverses this. Equipment adapts to your requirements. Process conditions are accommodated. Material compatibility is confirmed. Site constraints are addressed. Safety requirements are met. Analytical methods are supported. Installation is simplified.
Custom drawings document everything. Dimensions fit your space. Connections match your piping. Materials resist your process chemistry. Pressure ratings exceed your operating conditions. Temperature management maintains sample integrity. Safety features meet your regulations.
The outcome is equipment designed for your application. No surprises, modifications or compromises.
The Cost of Wrong Equipment
What happens when you install the wrong sampling system? The problems show up fast and compound quickly.
Operational Problems
Take a bottle system installed on high vapor pressure liquid. It fails immediately. Propane flashes to vapor. Operators cannot collect samples. The lab receives gas instead of liquid. Analysis fails. Production decisions lack data. Quality control stops. Shipments are delayed.
Equipment Replacement
At that point, you need different equipment. You pay for two systems instead of one. The first system has no value. Installation labor doubles. Disposal costs accumulate. Time is lost waiting for correct equipment.
Safety Problems
Beyond the operational costs, a bottle system on high vapor pressure material can rupture a bottle during sampling. Flammable vapors create fire and explosion hazards. Toxic vapors create health hazards. Personnel exposure occurs. Regulatory violations follow. Incident investigations consume time and resources. Citations are issued. Fines are assessed.
Field Modifications
When equipment almost fits, it requires modifications. Field fabrication. Additional materials ordered. Extra installation time. Quality control concerns. Documentation gaps. Warranty issues.
Equipment matched to your application from the start prevents all of these problems. Custom drawings with expert engineering consultation ensure you receive the right system the first time. Engineered-to-Order eliminates the cost of wrong equipment.

Making the Right Choice
Not sure where to start? These are the questions that determine which system fits your application
- What material are you sampling?
- What is the vapor pressure at collection temperature?
- What are the process pressure and temperature?
- How much sample volume do you need?
- Will the material stay fluid during transport?
- What are the safety and emissions requirements?
- What special material characteristics matter?
- What are your site constraints?
- What does your installation environment look like?
Answers to these questions determine equipment type and design details. Vapor pressure determines whether you need bottle or cylinder systems. Process pressure and temperature add constraints. Material properties drive construction material selection. Safety requirements add features. Site constraints affect configuration. The installation environment influences mounting and integration.
