Temperature Sensors

Temperature sensors and temperature probes

We sort temperature probes by design, not by sensing element. The reason is a practical one: you know how the probe has to be installed – screwed in, laid against a surface, hung in a room – and many designs take either sensing element anyway, resistance thermometer as well as thermocouple.

• Screw-in probes with a process connection, for measuring in the medium
• Magnetic surface probes and spring-loaded contact probes for cases where no intervention in the process is possible
• Infrared sensors for non-contact measurement on moving and very hot surfaces
• Room probes for cold rooms, air-conditioning and building services
• Wireless probes for measuring points no cable reaches

Signal and evaluation

Some of the probes already carry the transmitter in the terminal head and output 4…20 mA, often with a superimposed HART signal, plus a display and limit contacts on the device. Anyone who prefers a passive probe and a separate transmitter will find the transmitters under temperature transmitters.

High temperatures

For applications beyond the usual range we supply sensors up to 600 °C. Background and selection criteria are on the page high-temperature sensors.

The range in the shop keeps growing – sheathed and cable probes, terminal-head versions, hand-held instruments, limit switches and marine versions to GL will follow over the coming weeks. If your design, measuring range or process connection is not there, please ask: office@octogon.org or +43 676 3628453 – we also supply special designs.
