Description
1. Overview of the Capsule Pressure Gauge, Stainless Steel MT-P100SC
The Capsule pressure gauge, stainless steel MT-P100SC is a specialized low-pressure measurement instrument engineered to provide accurate indication of positive, negative, and differential pressure in gas systems. Unlike Bourdon tube gauges that work efficiently at medium or high pressures, capsule-type pressure gauges use a thin double-diaphragm capsule system that responds to even very small changes in pressure. This makes the MT-P100SC an essential device in HVAC systems, laboratory research setups, gas handling networks, environmental monitoring equipment, burner controls, and clean air distribution processes.
Constructed with a stainless steel case and internal parts, the MT-P100SC is exceptionally durable, corrosion-resistant, and suited for industrial environments where reliability and long operational life are critical.

3. Working Principle of Capsule Pressure Gauges
The Capsule pressure gauge, stainless steel MT-P100SC uses a capsule sensing element, which consists of two corrugated stainless steel diaphragms welded together. When pressure is applied, the capsule expands or contracts depending on the pressure differential. This movement is transmitted through a mechanical linkage to the pointer, which displays the pressure value on the dial.
This mechanism is ideal for:
-
Measuring extremely low pressures
-
Detecting small pressure fluctuations
-
Monitoring vacuum conditions
-
Ensuring gentle, non-pulsating pressure response
Because the capsule mechanism responds sensitively to small changes, the MT-P100SC is widely preferred for clean, dry gas applications.
4. Stainless Steel Construction and Its Advantages
One of the key benefits of the MT-P100SC model is its stainless steel body and internal components. Stainless steel construction provides:
| Advantage | Explanation |
|---|---|
| Corrosion resistance | Suitable for slightly aggressive gas environments |
| Hygienic and cleanable surfaces | Ideal for laboratory and medical gas systems |
| Mechanical durability | Ensures stable long-term use without deformation |
| Temperature resistance | Suitable for fluctuating ambient and process temperatures |
Because of these features, the gauge is more durable compared to brass capsule gauges and offers superior performance in demanding industrial applications.
5. Dial Size Options and Visibility
The Capsule pressure gauge, stainless steel MT-P100SC is available in three dial diameters:
| Dial Size | Typical Installation Area |
|---|---|
| 63 mm (2.5″) | Compact systems, control panels, equipment enclosures |
| 100 mm (4″) | General industrial environments and equipment monitoring |
| 160 mm (6″) | Remote visibility zones, control rooms, and monitoring centers |
Larger dials (especially 160 mm) provide improved readability for operators who monitor gauges from a distance.
6. Pressure Range Variations and Application Suitability
The MT-P100SC supports a variety of low-pressure measurement ranges:
-
0…16 mbar – suitable for very low, micro-pressure ventilation systems
-
0…600 mbar – used in gas supply lines and environmental monitoring
-
-600…+600 mbar – ideal for vacuum and slight positive pressure in HVAC systems
This flexibility makes it suitable for:
-
Air filter performance monitoring
-
Combustion furnace draft control
-
Clean room pressurization control
-
Gas distribution and regulation
-
Airflow and pressure differential measurement
⚠️ Note: The gauge is intended only for clean, dry, non-condensing gases. Liquids or corrosive gases may damage the capsule element.
7. Mounting Style and Process Connection
The bottom connection and direct mounting pattern make installation simple in most standardized panel and piping arrangements. The ½” NPT (M) process connection is commonly used in gas regulators, HVAC manifolds, burner controls, and pressure sensing modules.
This mounting design allows:
-
Fast installation
-
Standard retrofitting to existing systems
-
Secure, leak-resistant piping connection
8. Ingress Protection and Operational Environment
With IP65 ingress protection, the Capsule pressure gauge, stainless steel MT-P100SC is resistant to:
-
Dust intrusion
-
Accidental water splashes
-
Standard industrial atmospheric exposure
The dry execution ensures smooth pointer movement and accurate readings without the damping effect of glycerin, which is important for low-pressure adjustments requiring fast response.
9. Advantages of Choosing the MT-P100SC
The MT-P100SC offers significant performance and operational benefits, including:
-
High sensitivity suitable for micro-pressure measurement
-
Strong stainless steel construction for durability
-
Clear visualization from large dial options
-
Accurate measurement of both vacuum and slight positive pressure
-
Reliable performance in HVAC, gas distribution, laboratory, and industrial systems
This makes the gauge a trusted solution for engineers, system designers, and process technicians.
10. Conclusion
The Capsule pressure gauge, stainless steel MT-P100SC is a precise, reliable, and industrial-grade instrument for low-pressure gas applications. Its stainless steel build, wide dial size options, multiple pressure ranges, and IP65 protection rating ensure long-term stability and accurate performance in demanding environments. Whether used in HVAC systems, laboratory pressure regulation, gas handling networks, or combustion monitoring, the MT-P100SC delivers dependable and sensitive pressure indication.
