Detail:
First, almost described:
XTRM remote temperature monitor adopts advanced microprocessor of intelligent control, it is suitable for display and control temperature, humidity, pressure, liquid level, instantaneous flow and speed a variety of physical quantity detection signal detection circuit multiplex measuring signals. And can be a linear correction of various nonlinear input signals with high accuracy. Intelligent digital control, the range can be set freely. Output control has two kinds: various recurrent alarm output / remote variable transmission output; multiple comparison after the highest measuring points as output (remote variable transmission output). The input / output circuit is used in the photoelectric isolation, which has good anti-interference ability. The pointer meter display two high brightness digital display, LED. The machine adopts hanging type structure (length * width * height =160 * 110 * 70mm), the installation is very simple.
This product can measure 2 to 4 measuring points, and the temperature in the various temperature measurement circuit, the highest temperature of a point as the output, the temperature in the field can be viewed through the key to watch the temperature.
