These specifications ensure that the MT-P200ST can withstand demanding working conditions while maintaining precise and stable measurement performance.
3. Advantages of Phenolic Case Construction
The defining feature of the MT-P200ST is its phenolic housing. This advanced polymer material is used in industrial applications where durability and chemical stability are required.
Benefits of phenolic construction include:
-
High heat resistance, preventing deformation in elevated temperature environments
-
Excellent chemical resistance, suitable for corrosive atmospheres and aggressive industrial fluids
-
Electrical insulation, increasing operator safety in electrically active environments
-
Impact resistance, minimizing the risk of cracking or damage during installation or operation
-
Lightweight yet strong, making it suitable for both stationary and mobile equipment
This makes the MT-P200ST an ideal pressure gauge for industries where ordinary metallic gauge housings may corrode or degrade prematurely.
4. Pressure Measurement Performance and Range
With a measuring range of -1…0…1600 bar, the MT-P200ST covers an exceptional range of vacuum and high-pressure applications. Whether monitoring suction pressure in pumps or extreme high-pressure hydraulic system performance, this gauge provides consistent and accurate readings.
The wide scale range is particularly useful in:
-
Hydraulic power units
-
Pneumatic testing systems
-
High-pressure pump installations
-
Industrial compressors
-
Gas regulation and boosting stations
The gauge is equipped with a highly sensitive bourdon tube or equivalent pressure-sensing mechanism, ensuring accuracy without unnecessary pointer vibration or drift.
5. Mounting and Installation Features
The Bottom, Direct mounting pattern allows the gauge to be installed directly onto pipelines, valve systems, or industrial panels. The ½” NPT (M) process connection ensures compatibility with standard industry fittings and supports leak-free installation when properly sealed.
Installation best practices:
-
Install at eye level for clear dial visibility
-
Use thread sealant or PTFE tape to ensure a secure and leak-free connection
-
Avoid installing in locations subjected to continuous vibration unless glycerin filling is used
-
Where applicable, install with a pressure snubber to protect against pulsation
The compact size makes the MT-P200ST suitable for systems where space is limited.
6. IP65 Ingress Protection and Environmental Durability
The IP65 protection level indicates that the gauge is dust-tight and protected against low-pressure jets of water. This feature ensures reliable use in environments exposed to:
-
Outdoor weather conditions
-
Industrial washdowns
-
Airborne dust and particulate matter
-
Humid or wet processing plants
This high protection rating enhances the lifespan of both the external housing and internal mechanisms.
7. Dry or Glycerin-Fillable Execution
The MT-P200ST is available in two execution types:
| Execution Type | Best Use Conditions | Advantage |
|---|---|---|
| Dry Type | Stable, vibration-free systems | Cost-effective, maintenance-free |
| Glycerin-Fillable | High vibration or pulsation applications | Smooth pointer movement, reduced wear |
Glycerin-filled gauges protect the internal mechanism by damping vibration, extending operational life, and providing easier reading under dynamic conditions.
8. Applications and Industrial Sectors
The Phenolic Pressure Gauge MT-P200ST is used across a wide range of industries:
-
Chemical Processing: Resistant to corrosive vapors and aggressive compounds
-
Oil and Gas: Suitable for processing and distribution networks
-
Hydraulic Systems: Measures extremely high system pressures
-
Power Generation: Ensures safe monitoring of boiler and turbine feed systems
-
Marine and Offshore: Withstands moisture-laden and salt-corrosive atmospheres
-
Pharmaceutical and Food Processing: Chemical-resistant case avoids contamination risks
Its rugged construction enables safe and accurate pressure supervision where precision and durability are critical.
9. Conclusion
The Phenolic Pressure Gauge MT-P200ST is a high-reliability instrument designed for challenging industrial environments requiring accurate pressure measurement and exceptional resistance to chemical and thermal stress. With its wide measuring range, phenolic housing, optional glycerin filling, IP65 rating, and universal NPT process connection, it delivers superior performance, longevity, and operational safety.
Whether installed in high-pressure hydraulic systems, chemical reactors, gas regulation systems, or industrial pump monitoring setups, the MT-P200ST ensures stable measurement accuracy and dependable operation, helping organizations maintain efficiency, safety, and system reliability.
