1. Brief introduction
LU-C series electric capacity type differential-pressure/pressure transmitters adopt world advanced, mature and reliable electric capacity sensors technology thereby with high efficacy, excellent performance, compact and firm structure, greatly favorable for users.
The intelligent types adopt CPU to enhance the nimbleness & function and communicate with HART protocol.
The high intelligent types adopt digital, multi-parameters sensors, the zero self-calibrated (keep for 8 years), with temperature sensor to real time temperature compensation and with display screen & communication programmable keyboard, convenient & facilitate.
