In today’s rapidly advancing industrial world, accuracy, reliability, and customization are not luxuries—they are absolute necessities. Every process plant, whether in the chemical, oil & gas, pharmaceutical, marine, power, or manufacturing sector, operates under unique conditions that demand highly specific measurement and control instruments. One of the most crucial among these is the pressure instrument—a device responsible for monitoring, controlling, and ensuring safety within complex systems.
However, not all pressure instruments are created equal. Standard gauges or transmitters often fall short when it comes to meeting unique pressure ranges, media compatibility, temperature extremes, or mounting requirements. That’s where custom pressure instruments come in.
Custom pressure instruments are specifically engineered to match an application’s precise demands—ensuring accuracy, durability, and seamless integration into existing systems. For companies like Japsin Instrumentation, designing and manufacturing customized solutions has become an art and a science—where engineering precision meets process understanding.
In this blog, we’ll explore everything you need to know about custom pressure instruments—what they are, why they matter, how they’re designed, their industrial applications, and how they help shape a safer, smarter, and more efficient industrial future.

1. Understanding Pressure Measurement in Industry
Pressure measurement is a cornerstone of industrial process control. In simple terms, pressure refers to the force exerted by a fluid (gas or liquid) per unit area. Monitoring pressure ensures that equipment operates safely, processes run efficiently, and end products maintain consistent quality.
Pressure readings are essential in systems involving:
- Fluid flow (like pipelines or pumps)
- Chemical reactions (within reactors)
- Storage tanks (to avoid overpressure)
- Filtration and purification systems
- Pneumatic and hydraulic circuits
When these measurements are inaccurate, it can lead to inefficiencies, product wastage, or even catastrophic equipment failure. Hence, industries rely heavily on pressure instruments—including gauges, transmitters, sensors, switches, and calibration devices—to keep everything in balance.
But what happens when “standard” instruments can’t handle a particular process condition? That’s where customization becomes vital.
2. What Are Custom Pressure Instruments?
Custom pressure instruments are specially designed devices engineered to meet unique operational requirements beyond standard catalog offerings. They are tailored in terms of:
- Pressure range and accuracy
- Process connection size or type
- Materials compatible with aggressive chemicals
- Operating temperature limits
- Environmental protection (IP ratings, hazardous area certifications)
- Electrical outputs or digital communication protocols
- Mounting orientation and display style
These instruments can be pressure gauges, transmitters, differential sensors, or calibration units—built specifically to suit one-of-a-kind process applications.
For instance, a chemical reactor using highly corrosive acid may need a Hastelloy C diaphragm-sealed pressure gauge, while an oil rig application might require an explosion-proof pressure transmitter with remote sensor assembly.
Such engineering precision ensures process reliability and extends the instrument’s service life—reducing maintenance costs and downtime.
3. Why Custom Pressure Instruments Are Important
Customization in pressure instruments isn’t just about aesthetics or branding—it’s about functionality, safety, and efficiency. Here are the top reasons industries prefer custom-built solutions:
a. Process Compatibility
Every industrial medium behaves differently. Fluids may be corrosive, viscous, or contain particulates. Custom materials like stainless steel, Monel, Tantalum, or PTFE-coated internals ensure chemical compatibility and instrument longevity.
b. Extreme Pressure and Temperature Handling
Some systems operate under ultra-high pressures (up to 1000 bar) or cryogenic temperatures (-200°C). Custom designs ensure the mechanical structure and seals perform reliably under these extremes.
c. Safety and Compliance
Custom instruments often adhere to ASME, ISO, ATEX, and CE standards for hazardous environments, ensuring personnel safety and environmental protection.
d. Space Constraints and Integration
In compact machinery or skid-mounted systems, space may be limited. Custom instruments can be designed with specific dimensions, connection orientations, or panel-mounted options to fit perfectly.
e. Digitalization and Industry 4.0 Readiness
Custom instruments can include digital sensors, wireless transmitters, or IoT connectivity, making them compatible with smart manufacturing ecosystems.
f. Enhanced Accuracy and Calibration
Custom calibration ensures precise readings within a specific pressure range, minimizing errors in critical operations like pharmaceutical filling or power plant turbine control.
4. Design and Engineering Process for Custom Pressure Instruments
The development of a custom pressure instrument involves multiple engineering stages, ensuring that the final product meets both functional and regulatory requirements.
Step 1: Requirement Analysis
The process starts with an in-depth understanding of the client’s application:
- What medium is being measured?
- What is the operating pressure and temperature?
- Is the environment corrosive or hazardous?
- What level of accuracy is required?
Step 2: Conceptual Design
Engineers at Japsin Instrumentation design the pressure sensing mechanism—whether Bourdon tube, diaphragm, bellows, or strain gauge—depending on application needs.
Step 3: Material Selection
Choosing the right material is critical for durability and accuracy. Options include:
- 316 SS for general applications
- Hastelloy or Monel for corrosive chemicals
- Inconel for high-temperature processes
- PTFE or Tantalum coatings for additional protection
Step 4: Mechanical and Electrical Customization
Design modifications may include:
- Thread type (BSP, NPT, Flanged)
- Display style (analog dial or digital)
- Output signal (4–20 mA, Modbus, RS485, HART)
- Sealed housings or explosion-proof enclosures
Step 5: Prototyping and Testing
Before full-scale production, prototypes are built and tested under simulated operating conditions—ensuring accuracy, repeatability, and robustness.
Step 6: Certification and Delivery
After rigorous QA checks, the instrument is certified per industry standards (ASME, ISO, or ATEX) and delivered ready for field installation.
