Type J Fixed bayonet style thermocouple for plastic and packaging
The Fixed Bayonet Thermocouple is a Wire and tube immersion
thermocouple with compressible spring and locking cap. Bayonet
Thermocouples are mainly used for applications which require longer
immersion depths. The probe of the Bayonet Thermocouple is more
rigid, and provides a more suitable contact in a deeper well. The
compressible spring outer covering and its locking cap, keep the
probe in place securely. The varied 90° Bayonet Thermocouples are
often selected for application where space is at a premium, and the
90° bend allows for a tighter, neater installation. All bayonet
Thermocouples have flexible extensions (over braid or armor styles)
that are ideal for connection to near, or distant junction boxes.

1). Thermocouples respond quite fast due to the positive contact to
the measuring surface.
2). The thermocouple sensor is mounted to the process with the use
of a fixed spring when a matching adapter is supplied.
3). The thermocouple sensors available are provided with a variety
of sheath materials including stainless steels, corrosion resistant
and high temperature oxidation resistant alloys.
4). Thermocouple temperature ranges are dependent on the bayonet
style, sheath & conductor diameter, and element calibration.
The common accessories are a threaded adapter with a locating pin
allowing the bayonet cap to be locked in place while under spring
tension. Also a pipe or hose clamp that has the adapter welded to
the clamp. The clamp sizes can be designed for a large variety of
pipe and vessel diameters.
1). Fixed bayonet thermocouples applications include temperature
measurement inside tubes and drilled out blocks, Where conventional
thermowells are not accessible. In casings and bearing housings.
Where temperature measurement is needed inside the wall of a plate
2). Fixed bayonet thermocouples are designed for quick replacement
and connection to a bayonet adapter that is threaded into extruder
barrels, injection molds and platens to control process
