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.
