Installation for Dew-point Monitor Temperature Controller

Dew-point is generally used to represent the air moisture content. In the application of drying some of plastic materials with strong hygroscopicity, it is needed to use dry air with a low dew-point to achieve the purpose of fully drying. Dew-point monitor is the device used to monitor air dew-point changes. Now some of Shini dehumidifying equipments have dew-point monitor as the option, which is used to monitor air dew-point when air is dehumidified by honeycomb rotor. This device is convenient for users to detect dew-point in a visual way.

1) Use blade to cut off the film and outline the reserved hole site on the SCD control panel.

2) Check if there are complete parts for dew-point monitor including:
Dew-point monitor head of meter, Dew-point transmitter assembly (dew-point detector, detection cable, washer), Copper joint and installation seat for dew-point monitor

7) Connect signal wires of the transmitter and power lines of dew-point monitor with the according terminals.
Connect contact No.1 and No.2 with power, supply is 220VAC.
Contact No.3, No.4 and No.5 are idle.
Connect contact No.6, No.7 and No.8 with the signal of transmitter. (C- Connects contact No.6, C+ connects contact No.7 and wire No.9 connects contact No.8
Transmitter connection (White and blue wire connect wire No.9, black wire connects C- and gray wire connects C+).
