Description

1. Brief Introduction
LU***4M intelligent controller is high accuracy digital display survey control meter for the liquid level, temperature and pressure. Matched with the sensors and transmitters, may constitute each kind of measuring ranges and specifications measuring control system for the liquid level, temperature and pressure.
LU***4M intelligent controller has four channels alarm output, each channel alarm output can willfully be set for the upper limit alarm or the lower limit alarm, may has ***0mA, ***0mA standard current transform output which can be freely set and the DC*4V/*0mA sensors power supply. There is light pillar to display PV.
