Guide for Multi-channel Instrument Selection

Multi channel digital display meter is often used for measuring and controlling thermal quantities. Commonly used thermal quantities generally include temperature, humidity, pressure, liquid level, material level, etc.

The multi-channel digital display consists of 4 series of products. The main differences are in the number of measurable channels and the functions that can be selected.

* more than 4 channels of multi-channel measurement needs can be selected as a tour detector.

The characteristics of multi-channel instruments are to achieve the operation and comparison between channels, and also to reduce the number of instruments and reduce the integration cost.

WPD2 is a dual channel input, which can realize the comparison function of difference value and value, average value operation and larger value and smaller value.

WPD4A can input 2~4 channel, LCD display.

Basic performance of WPD2 dual channel digital display meter

2 input and 2 independent display.

It has 0.2 level accuracy, and the speed of measurement and control is 0.4 seconds (0.2 seconds *2 channel).

The difference, sum and average value of the measured signals of 2 channels, as well as the operation and comparison function of larger values and smaller values.

* * * 4 more alarm output, can be set to 2 channel measurement value or operation value of the upper and lower limits.

* * * 2 multiple output, can be set to 2 channels of measured value or operation value.
