External / Rugged Air Temperature PRT's (Type 74)
This air temperature sensor is ideal for external applications as the connections are enclosed in a weatherproof connection box. It is also most suited to internal applications which require box to be rugged. The sensor itself is housed within a perforated stainless steel tube which allows a free flow of air across the sensor element which in turn will give a good response time. An optional 4 to 20mA transmitter for those requiring a standard transducer signal is also available. Supplied in tolerance classes B or A in a 3 or 4-wire configuration. Operating temperature range: -30ºC to +150ºC.
