FK-PX400-G 2088 Housing High-Temperature Digital Pressure Transmitter

  • Product overview

The 2088 housing high-temperature digital pressure transmitter adopts an imported high-precision, high-stability diffused silicon pressure sensor. The internal electronic amplifier converts the sensor’s measured signal into standard output signals, including current, voltage, and RS485 communication.

Equipped with a local digital display, the transmitter allows direct on-site pressure indication, improving operation convenience and maintenance efficiency. The robust 2088-style housing provides strong mechanical protection and environmental adaptability, making the transmitter suitable for industrial process control and high-temperature applications.

The transmitter can be directly connected to PLCs, control instruments, intelligent meters, and DCS systems, enabling reliable pressure monitoring and control in demanding industrial environments.

FK-PX400-G 2088 Housing High-Temperature Digital Pressure Transmitter

  • Measuring principle

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

This deformation causes a corresponding change in the resistance of the diffused silicon elements. The internal electronic circuit detects and amplifies this change and converts it into a standardized electrical signal corresponding to the measured pressure value.
