Description
1. Introduction to Differential Pressure Gauge with Magnetic Piston MT-P200DP
The Differential Pressure Gauge with Magnetic Piston MT-P200DP is a precision-engineered measuring instrument used for monitoring the pressure difference between two points in a process system. This gauge utilizes a magnetic piston technology, which makes it highly reliable, stable, and suitable for a wide range of industrial applications. The MT-P200DP is commonly used in filtration systems, pump systems, ventilation ducts, pressure vessel monitoring, and hydraulic circuits where accurate indication of differential pressure is essential for maintaining operational efficiency and safety.
Differential pressure gauges help detect system blockages, filter saturation, abnormal flow resistance, and pump failure before they lead to costly downtime or damage. The MT-P200DP stands out due to its ability to function in harsh and vibration-prone environments, offering long service life, easy readability, and stable performance. Its magnetic piston sensing system ensures there is no direct mechanical linkage between the measured media and the gauge mechanism, improving durability and preventing contamination.
2. Key Technical Specifications and Operating Features
The Differential Pressure Gauge with Magnetic Piston MT-P200DP is built to meet demanding industrial standards. Key specifications include:
-
Dial Size: DN100 / DN160 (100mm or 160mm) for excellent readability
-
Pressure Range: 0…16 mbar…40 bar, suitable for both low and high differential pressures
-
Mounting Pattern: Direct, Bottom connection, designed for simplified installation
-
Process Connection: ¼” NPT (F) x 2 Nos, 37mm center-to-center spacing, ensuring compatibility with standard pipeline differentials
-
Ingress Protection: IP65, protecting the internal mechanism from dust and low-pressure water sprays
-

These specifications allow the MT-P200DP to be installed in compact spaces and integrated into both new and existing monitoring systems without special modification.
3. Magnetic Piston Sensing Technology
Unlike diaphragm or Bourdon tube differential gauges, the MT-P200DP uses a magnetic piston mechanism. This piston moves in response to pressure differences between two chambers. The piston’s movement is transferred to the gauge pointer magnetically, ensuring no direct mechanical contact with the process fluid.
Advantages of Magnetic Piston Technology:
-
No contamination of internal components, increasing gauge lifespan
-
Excellent repeatability and stability in readings
-
Lower maintenance requirements
-
Suitable for viscous or particulate-containing media
-
Smooth pointer movement with minimal friction
This makes the MT-P200DP an ideal choice for systems where process media may contain contaminants that would damage more delicate sensing mechanisms.
4. Dial Readability and Measurement Clarity
The DN100 and DN160 dial sizes provide clear and easy-to-read graduation marks, allowing operators to quickly interpret measurements from a distance. The scale can be customized in:
-
mbar
-
bar
-
kPa
-
psi
-
Dual or multi-scale formats if required
The high-contrast dial layout improves operational visibility in low-light environments, machine rooms, and outdoor installations.
5. Installation and Mounting Configuration
The gauge is designed for Direct Bottom Mounting, which simplifies connection to pipeline systems. The ¼” NPT (F) dual process connections with 37mm spacing fit directly into standard differential measurement ports on filters, pumps, and pipelines.
Installation recommendations:
-
Mount at eye level for the best visibility
-
Ensure both pressure ports are clear and free from debris
-
Install isolation valves for maintenance without process interruption
-
Use vibration-damping liquid filling for systems with mechanical shock or pump pulsation
When installed correctly, the MT-P200DP delivers stable long-term measurement accuracy with minimal recalibration.
6. Application Areas and Industrial Use Cases
The Differential Pressure Gauge with Magnetic Piston MT-P200DP is widely used across multiple sectors due to its robust construction and reliable performance. Key application areas include:
-
Filtration Systems: Detecting clogging or pressure drop in air, gas, oil, or water filters
-
Pumping Systems: Monitoring pump inlet vs. outlet pressure to evaluate performance
-
