Model AS-TS Temperature Switch
Brand: Fluid Components International LLC (FCI)FCI Aerospace Division provides a complete line of temperature switches that feature up to 3 different switch points in a single sensor. The sensors use a Resistance Temperature Detector (RTD) and FCI’s electronic package to provide discrete high and low outputs at customer specified temperature ranges. If it is specified that only two switch points are needed, the sensor can be modified to provide a conditioned Analog output from the RTD in lieu of the third switch point. The lightweight, small package design can be used in a variety of aerospace and military applications.
The sensors are typically packaged in AISI 300 series stainless steel bodies and can be designed to support a variety of installation techniques. Custom designs can provide sensors made from aluminum, titanium, and other thermally conductive materials. Switches can be provided with a flange or threaded mounting connection. The threaded mounting connection includes straight military or aerospace style fittings that seal with O-rings or gaskets, or National Pipe Threads (NPT) that seal with pipe sealant or tape. The flanged mounting is available in a number of arrangements that will mate with virtually any customer’s process connection.
