SMAR LD301 HART Pressure Transmitter

Core Performance & Industrial Application

The SMAR LD301 belongs to LD300 series intelligent transmitter with HART protocol. It adopts capacitive sensing technology, used for differential pressure, gauge pressure, absolute pressure, liquid level and flow measurement. It supports 4-20mA analog plus HART digital communication, built-in PID control, tank linearization and flow totalization functions. It has high measuring accuracy and wide turndown ratio, can be equipped with LCD local display, supports zero/span calibration and parameter configuration on site, suitable for continuous measurement in hazardous process sites.
