1 XTRMRemote monitoring deviceAdopting advanced microprocessors for intelligent control, it is suitable for display control of various physical quantity detection signals such as temperature, humidity, pressure, liquid level, instantaneous flow rate, and speed, and can perform cyclic detection of multiple measurement signals. And it can perform high-precision linear correction on various nonlinear input signals. Intelligent digital control, range can be freely set. There are two types of control outputs: each loop alarm output/remote transmission output; The highest measurement point after multi-channel comparison is used as the output (remote transmission output). Both input and output circuits adopt optoelectronic isolation, which has good anti-interference ability. It has two types: high brightness LED digital display and pointer meter display. The whole machine adopts a wall mounted structure (length x width x height=160 x 110 x 70mm), which is very easy to install.

This product can measure 2 to 4 measurement points simultaneously, compare the temperatures in each temperature measurement circuit, and output the highest temperature point. On site, the temperature of each point can be viewed one by one through buttons.
