Relative pressure transmitter LFT2010

piezoresistivesilicon4-20 mA

Overview
LFT2010 high-accuracy pressure transmitter uses an oil-filled diffusion silicon sensing element and laser-resistance trimming for zero and temperature compensation across a wide temperature range. Compact and easy to install, it integrates a low-power MCU to convert measured pressure into stable standard analog or digital outputs. Designed for industrial fluid pressure measurement in high-precision test systems, fire protection, water treatment and supply, pneumatic systems and factory automation.
