Temperature Sensors

Temperature measurement is essential to the proper functioning of your process.
We offer 2 temperature sensor technologies: thermocouples and platinum Pt100 .

We have a range of J or K type thermocouples available from stock. Customly-made, we also offer models type T, S, N .. adapted to your process, covering a wide temperature range.

Platinum Pt100 or RTD probes, 2, 3 or 4 wires, are renowned for their stability over time and allow more precision in temperature measurement but are slower than thermocouples, especially for ranges below 400°C.

Straight sheathed sensors

Technical characteristics

Sheathed Pt100 thermocouples and probes are small diameter, malleable and very reactive sensors. Also called mineral insulated temperature sensors, because insulated by compacted magnesia, they have a very good resistance to vibrations.

Rigid temperature sensors can be provided with a sheath protecting the measurement point. They are unsheathed. Their maximum temperature is limited by the type of cable used. They are used for example in boreholes, or for measurements in air flows.

For each of the ranges, we offer type J thermocouples and stock Pt100 probes .
