4 to 20 mA Outdoor RTD Temperature Probe

Comeco's TSOP outdoor temperature sensors measure temperature by means of a Pt100 sensitive element mounted in a thin stainless steel stem for fast response. The -20 to 60 ºC temperature range is converted to standard 4 to 20 mA, 2-wire signal.

The sensor electronics are enclosed in a freely mountable robust aluminium enclosure with IP66 protection class. A PG7 cable gland allows for cable entry. The sensor element is enclosed in a ⌀4 mm stainless stell stem that extends 20 mm from the sensor body. Thanks to their simplicity, small size and robust construction these sensors are applicable for various outdoor applications, environment temperature control, climatic temperature measurement, etc.
