Wet and Dry Bulb sensor overview

The Wet and Dry Bulb is a sensor to determine humidity percentage readings. We use this sensor with a dew point table to calculate the humidity. For use with the Climatica Plus, MetPlus and EWS weather stations. The sensor is covered with a Stevenson screen styled louvred enclosure. Designed to keep direct sunlight from making contact with the temperature probe. This will also allows free circulation of airflow. A dew point table is supplied.

Outside Temperature

This sensor also shows outside air temperature measurements when connected to an Instromet weather station.

Sensor cable and mast mounting

The sensor is supplied with 2 x 25 metres of two core cable and a mast mounting 55 mm opening U bolt.

Installation Instructions

This unit can be wall or mast mounted. It should be fitted where there is free movement of air. Keep away from heater and ventilation outlets. Also keep away from chimneys, warm walls and flat roofs, which may radiate heat during sunny periods. The length of the cable affects the calibration and therefore should not, if possible, be shortened or lengthened.
