LEFOO LFT3100 temperature and pressure 2 in 1 transmitter adopts advanced piezoresistive pressure sensor and PT-100 temperature sensor, which is converted into standard output signal through special signal conditioning circuit, with advanced temperature digital compensation, wide operating temperature range, and full output signal It is suitable for the monitoring of pressure and temperature in crude food and water treatment systems.
Feature
* Adopt oil-filled diffusion silicon core with high precision and high overload capacity
* Temperature and pressure dual output, compact structure, saving installation space
* Support Modbus-485 communication protocol (intelligent type)
* The temperature sensitive element and the pressure sensitive element are packaged as one, which is closer to the medium temperature
