详情

I. Product features:
The sensor body is made of PVDF material with excellent corrosion resistance;
The sensor adopts special alloy probe and thread installation;
With alarm indicator light;
St standard guide rail installation;
II. Introduction   
Liquid alarm unit is widely used in gas sample control system of monitoring and analysis instruments. This reliable failure of the condensate device can be monitored by a high cost alarm and maintenance of the condensate device. If this kind of fault occurs, the gas sampling system can cut off the power supply of sample gas pump or solenoid valve according to the alarm signal.
The liquid humidity alarm unit is composed of humidity sensor module and alarm control module;
The alarm module is powered by *4 V DC, and there are two LED lights on the panel, green and red indicator lights, respectively for the display of no alarm and alarm; at the same time, it provides an alarm output, and the gas sampling system can switch the working power supply of the system's solenoid valve or pump according to the alarm signal;
