BTS1 Screw-Threaded Temperature Sensors

A range of screw-threaded temperature sensors with a 1/8″BSP gas thread and integral plug-in locking connector.  These sensors can be supplied with a wide range of NTC  thermistors or platinum sensors (e.g. Pt100, Pt1000 etc.) to help fine-tune it for a particular application.  Other sensing element options are also possible.

These are cost-effective probes that offer a neat solution for fluid temperature measurement and control.  Originally designed for use in gas boiler applications, they can be used anywhere that you want to sense or control temperature of a liquid in a pipe or vessel.  Various connector types are available or integral flying leads (with or without end connectors) can also be supplied.
