Barber-Colman Company TKS-2031-0-1 Temperature Controls

Barber-Colman TKS-2031-0-1 Temperature Transmitter with Remote Bulb is a pneumatic temperature sensor that provides a process temperature signal to Barber-Colman control loops. The remote bulb is placed at the process and senses temperature, translating it into a pneumatic pressure signal for compatible Barber-Colman controllers, enabling proportional control of heating or cooling elements. This model is specified for a temperature range of 40–160°F (approximately 4–71°C). Market listings describe it as a temperature transmitter with remote bulb; distributors note that this item has been discontinued by the manufacturer and has a replacement in the 2252-703 series. Typical applications include industrial process temperature monitoring and control where a pneumatic signal is preferred, such as ovens, dryers, boilers, and other process equipment that relies on remote temperature sensing. The TKS-2031-0-1 represents Barber-Colman’s lineage of pneumatic temperature instrumentation and is recognized in legacy catalogs and second-hand inventories as a remote-bulb transmitter designed to interface with Barber-Colman pneumatic controllers and accessories.
