Humidity Sensor - HCS-4/3

Grain Watch™ Humidity Sensor HCS 4/3 consists of a holder with sensors and two 4 meter long cables to be mounted inside the dryer accordingly to instructions. The mounting in the dryer is best done using no tools.

The design of the Humidity Sensor prevents straw from sticking to it, thus leading to misleading data. Depending on the width of the dryer, on or two humidity sensors can be used.


Mounting the humidity sensor

In the picture below, right, you can see the first row of beams/members at the mark “X”, where the drying zone meets up with the cooling zone. In height the Humidity Sensor should be mounted in the row of beams/members at “A” on the intake side.

If possible, mount the sensor in one of the air beams/air members in such a way that it is placed one third of the dryer’s full width from one side. If this is not possible, you can mount the sensor closer to the centre, but not close to one side.

Example: When dryer full width = 1.5 m, the sensor should not be closer to one side than 0.5 m.

In case you mount two sensors, place them symmetrically or evenly spaced, about half of the dryers full width between the two sensors.

Example: When dryer full width = 4 m, the distance between the sensors should be 2 m.

No tools needed to mount sensor

The Sensor is designed to be mounted without tools. See picture below. Tighten screw “2” and slightly unscrew the two screws called “3”. Insert the sensor inside the air beam/air member. The Sensor should rest in the triangular opening, and the lip underneath must be inside the dryer.

Adjust screw “2” until the sensor levels horizontally. Tighten the two screws “3” with your fingers, making sure the sensor is pointing straight into the air-beam/air-member. Tighten the screws until the sensor is well fixed.

Do not overtighten these screws. Normally, tools are unnecessary.
