BDTH01-02

Dew Point Meter

This dew point meter, equipped with up to two relays, can not only monitor the instant dew point, but also convert the analog signal from dew point sensor into 4-20mA that can be transmitted to other devices. Additionally, With RS485 Modbus RTU interface, the dew point meter can connect to the PLC or HMI conveniently. The panel cutout dimension is a standard size that reduces time and complexity on installation.

To control the dew point in industrial processes, people may mount the hygrometer or dew point transmitter to maintain an optimal humidity condition. Dew point can play a critical role in control systems. For instance, compressed air systems often require to maintain the moisture in compressed air pipes. To monitor the dew point, you can connect our dew point sensor to this digital panel meter, and use its alarm function to set up your high and low alarm limits.
