Air temperature sensor in shelter

The temperature sensor type 2033 is equipped with a platinum resistance Pt 100, DIN 60751 B, 1/3 tolerance, with 4-wire connection, incl. 5 m measuring cable.

The sensor is placed in plastic shaft and screwed into the base plate by means of a cable duct. The base plate provides 2 holes, 30 mm distance, for M8-screws for fastening.

The protection shelter is designed to avoid influence from radiation, precipitation etc.. It consists of single segments plus a top cover, made of a special white plastic material.

Following versions are further available:

Version with electrical ventilation, to obtain exact measuring values even with total calm. The air flow speed is about 3 m/s.

Version with measuring converter which is placed in a housing underneath the sensor. Outputs are 4...20 mA or 0...10 V.
