INTRODUCTION
The
225-WS-32THA Temperature and Relative Humidity Sensor
is highly accurate and easy to use. The
replaceable humidity sensor element and RTD temperature sensor are protected by a filter/cap which
screws into the stainless steel body. The probe is detachable from the cable by means of an M8
connector. The probe is protected by a solar radiation shield that blocks direct sunlight and deflects
precipitation. The mounting bracket/U-bolt fits a 1 ½" mast (not included).
Relative humidity is measured by a thin film capacitive sensing element. The sensor range is 0 to 100%
relative humidity with a 0 to 1 volt output.
Temperature is measured by a 1000 ohm RTD element. The sensor range is -40 to +60°C (-40 to
+140°F) with a 0 to 1 volt output.
The
225-WS-32THA
is equipped with 40 feet of cable with tinned wire ends. The sensor can be ordered
with additional cable, if needed.
