Digital Pressure Sensor LFT2800

This type of pressure transducer uses a piezoresistive pressure sensor with a stainless steel isolation film as the signal measurement component. The zero-point and temperature compensation for wide temperature ranges is carried out by the laser trimming process. By using a low-power high-performance MCU, the pressure signal is collected and converted into a digital signal through RS485 output, which adopts the international standard Modbus protocol. It can be widely used in the measurement of medium pressure in test systems such as fire fighting, water treatment, water supply systems, air compressors, pneumatic devices, and factory automation, etc.


Features


*Imported oil-filled silicon core
