Scope of application

The WT-XMDA intelligent patrol instrument is used in conjunction with all kinds of sensors and transmitters. It can carry out circuit inspection, alarm control, transmit output, data acquisition and communication for industrial process parameters such as multi-channel temperature, pressure, liquid level, flow rate and weight.

Functional characteristics

Universal input function
Automatic calibration and manual calibration function
Multiple protection, isolation design, strong anti-interference ability and high reliability.
A good software platform of intelligent patrol instrument has two development capabilities to meet special functions.
The advanced modular structure of intelligent patrol instrument, with powerful instrument chip, function combination and system upgrade are very convenient.
Automatic inspection and manual checking can be switched freely.
The channel switching time and the effective number of channels can be set.
