Humidity Tansmitter

The transmitter measures the humidity by the honeywell humidity sensor HIH-3610. The transmitter analog output may be be 0-10V or 4-20mA. And the transmitter include a noise filter.the power suply is large range VDC18V----VDC30V.The humidity transmitter measurement range is 5%-95%.

Ordering

Ordering number:RH-5I-D or RH-5I-D-T

-5 indicates the humidity transmitter accuracy is 5%; -3 indicates 3%, -2 indicates 2%.

-I indicates the humiditt transmitter signal out is 4-20mA. If U indicates the signal is 0-10V.

-T indicates the humidity transmitter integration with temperature signal out.

For example:RH-5I-D-T

The duct humidity transmitter signal out is 4-20mA and the temperature signal out is 4-20mA.

Installation

Duct probes should be installed directly on the duct, in an area where the air stream is well mixed:

· Locate a supply air sensor two or three meters down stream from the nearest fan and coil.

· Mount the return air sensor close to the air inlet but downstream from a return fan if one is present.

· To install the sensor, assemble base plate and probe, then drill a 12 mm hole and two 3 mm holes on a diameter of 25 mm in the duct.

· Use two self-tapping sheet metal screws to tighten the mounting circuit in the cover.

· Connect the wires according to the wiring diagram to the measuring circuit in the cover:

o Only the humidity transmitter signal out need three terminal connections,DC24V,Ground and humidity signal out.

o If humidity and temperature transmitter signal out need for terminal connections,DC24V,Ground,humidity signal out and temperature signal out.

o The connection signal cable should be shield wires.

· Assemble the cover with the mounting plate.

· Insert the assembled probe through the center opening of the mounting plate into the air stream.

· Tighten the horizontal screw on the mounting plate to fix the probe to the duct.
