Model Selection and Functional Comparison of Diffused Silicon Pressure Transmitters

In the field of industrial automation, the selection of the 7MF-MF1564 pressure transmitter directly affects system stability. In view of different requirements for diffused silicon sensors, this article provides a detailed comparison of the functional differences among models such as PT-B, TS-TS201/203/204, and NPT-NPT102 in maintenance, alarm control, remote signal transmission, and more, helping you choose the most suitable pressure transmitter solution according to specific application scenarios.

1. Basic PT-B Series: Maintenance and Routine Applications

The PT-B pressure transmitter adopts diffused silicon sensing technology and is specially designed for stable measurement of liquid and gas media. Its core advantages lie in the simplified maintenance process:

• Automatic temperature compensation function reduces calibration frequency
• 316L stainless steel isolation diaphragm resists corrosive media
• IP65 protection rating adapts to industrial on-site environments

It is especially suitable for scenarios requiring long-term stable operation, such as water supply systems and compressed air monitoring. When used together with scenarios requiring precise position control (such as a valve opening instrument system using the domestic WPS-S draw-wire displacement sensor), it is recommended to choose the PTB-PTB505 model with a G1/2 interface.

2. Functional Analysis of the Intelligent Control TS-TS200 Series

This series includes three differentiated models to meet different control requirements:

2.1 TS-TS201 Alarm Control Type

Integrated with two relay outputs, it can be set for:

It is typically used for overpressure protection in hydraulic systems, forming an electromechanical interlock safety system together with displacement monitoring equipment (such as the 50000mm range version of the WPS-S sensor).

2.2 TS-TS204 Remote Signal Transmission Type

It adopts 4-20mA+HART protocol dual output, with advantages including:

• Maximum transmission distance up to 3000 meters
• 40% improvement in electromagnetic interference resistance
• Supports Modbus RTU protocol conversion

3. Solutions for Special Application Scenarios

For specific industrial scenarios, customized configurations are required:

3.1 Key Points of the NPT-NPT102 Manual

This model includes complete safety operation guidelines:

1. Do not use under pressure exceeding 125% of the measuring range
2. Medium temperature must be maintained within the range of -20~85℃
3. Perform zero-point calibration at least once a year

3.2 7MF-MF1567 Custom Services

Adjustments can be made according to requirements:

• Process connection method (flange/thread)
• Output signal type (0-10V/RS485)
• Explosion-proof certification level (Ex ia IIC T6)

4. System Integration Recommendations and Maintenance Points

To ensure optimal performance, it is recommended to:

• Perform synchronized calibration with displacement monitoring equipment (such as a draw-wire encoder with accuracy up to 0.01%FS)
• Check the condition of seals every 6 months
• Use the dedicated debugging software provided by the manufacturer

Summary and Professional Recommendations

When selecting the 7MF-MF1564 series pressure transmitter, it is necessary to comprehensively consider the measured medium, control requirements, and environmental factors. For scenarios requiring high-precision mechanical interlocking, it is recommended to pair it with the WPS-S series displacement sensor to build a complete measurement system.
