Ceramic Protection Tube Temperature Sensors

Head Sensors with Ceramic Tube
TT..CU-22, TT...C-22, TT...CC-22, TT...C-42, TT...ACT, TT...CS-22, TT...GWC-1..., TT...CT-22. The sensors as above are equipped with either a
terminal block or with a 4-20 mA transmitter (designated as APTT) instead of the terminal block.
The sensors as described above comply with the Polish Standard PN-EN 60584.

Construction and principle of operation.
Measuring thermoelectric insert in outer ceramic tube is a principal element of the
sensors represented in this Manual. The clamps of this insert are protected by a connection
head made of aluminium alloy. Inside the sheath, there is a thermocouple connected with the
clamps of terminal block or of 4-20 mA transmitter. The sensors of these series are fixed on
external gauges by the use of either slidable or threaded clamping holders.
The measuring element of insert responds to a change in temperature of a medium by
changing its electromotive force EMF /thermocouple/. The changes correspond to their
thermometric characteristics as defined in the Polish standard PN-EN 60 584.

Specification:
Thermocouple: 1 or 2x Fe-CuNi /J/; NiCr-Ni /K/; PtRh10-Pt /S/; PtRh13-Pt /R/ Class 1, 2; PtRh30-PtRh6 /B/ Class 2, 3 according to PN-EN 60584
