TS3 – the flexible temperature probe

SmartSpacer, SmartDisc, SmarrBusbar mounting accessories for TS series temperature probes


Fiber Optic Temperature Sensor

The fiber optic temperature probe TS3 is the best choice for use in RFI, EMI, NMR and microwave environments and compatible with all FOTEMP series instruments. The TS3 probe has a a measurement range of -200°C to +300°C with an accuracy of +/-0.2°C.

Unlike the TS2 sensor TS2, the TS3 comes with the option of a customizable length of semi-rigid polyimide probe tip from 10mm to 130mm.

With a maximum diameter of 1.7mm, the small profile TS3 probe can fit in the smallest openings and ideal for insertion into non-caustic media such as food, liguids, powders and cultures for monitoring real-time temperature.

Starting at 850nm, GaAs becomes optically translucent for which the position of the band gap is temperature dependent. The FOTEMP signal conditioners contain a light source and a device for the spectral detection of the band gap.
