AS-TE Temperature Sensor

FCI AS-TE is a compact, light-weight, precision temperature sensor for direct installation into piping and ducting on commercial and military fixed wing or rotary aircraft as well as spacecraft, vehicles and shipboard/marine vessels. These elements utillize high accuracy, highly repeatable RTD sensors (Resistance Temperature Detectors) to provide a linear change in resistance directly proportional to temperature changes in the liquid or gas process. customer. These sensors are packaged in all welded, sealed thermowells for superior service life.  AS-TE can be specified with threaded or flanged conections and wiring connectors to match your installation need.
