FK-P300-E Diffused Silicon Pressure Transmitter

  • Product overview

The pressure transmitter adopts an imported high-precision, high-stability diffused silicon sensing element. An internal electronic amplifier processes the sensor signal and converts it into a standard output signal, including current, voltage, or RS485 digital communication.

Designed for industrial environments, this transmitter provides accurate measurement and control of gauge pressure, absolute pressure, and sealed reference pressure for various liquid and gas media. Its robust structure and advanced isolation technology ensure reliable operation in demanding applications across petroleum, chemical processing, steel production, electric power, light industry, and environmental protection sectors.

 

  • Key Features

Compact Structure: Small size and flexible installation options.

Advanced Diaphragm Isolation: Diaphragm and oil-filled isolation technology ensures accurate and stable measurement.

High Stability & Reliability: Designed for long-term operation in industrial environments.

Strong Anti-Interference: Excellent resistance to vibration, shock, and RF interference.

316L Stainless Steel Diaphragm: Suitable for a wide range of industrial fluids.

All-Stainless-Steel Construction: Enhances durability and corrosion resistance.

Multiple Signal Outputs: Supports voltage, current, and RS485 communication.

Wide Measuring Range: Capable of measuring gauge pressure, absolute pressure, and sealed reference pressure.

Flexible Configurations: Multiple structural forms available for convenient installation and use.

 

  • Measuring principle

The transmitter operates based on the piezoresistive effect of a diffused silicon pressure sensor. When the measured medium applies pressure to the sensor diaphragm, the diaphragm undergoes a micro-displacement proportional to the applied pressure.

This deformation causes a corresponding change in the resistance value of the piezoresistive elements. The electronic circuit detects this resistance variation, amplifies and processes the signal, and converts it into a standardized electrical output proportional to the applied pressure.
