Model AS-TT Temperature Transmitter
Brand: Fluid Components International LLC (FCI)FCI Aerospace Division provides a complete line of temperature transmitters that feature an Analog output as a function of process temperature.
The sensors use a Resistance Temperature Detector (RTD) and FCI’s electronic package to provide a 4-20 mA or 0-5 V output at customer specified temperature ranges. As an added benefit, the same sensor can also optionally serve as a temperature switch that provides a discrete high or low output at two different temperature set points.
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.
Transmitters 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 Thread (NPT) that seal with pipe sealant or tape. The flanged mounting is available in a number or arrangements that will mate with virtually any customer’s process connection.
