STX140
The STX140 is made of polythene tube Ø 10mm and is primarily intended for
laying underfloor. Four thermistors are evenly spaced along the length of the tube.
The sensor is delivered with a connection cable of two metres.
When laying underground, the thermistor cable should be placed in pipes with a
minimum inside diameter of 12mm.
Accuracy See Appendix A: Table D
STX120, 520
The sensor, which is made of stainless steel, is delivered with a 2m or 4m cable
PVC sheathed overall. STX120 is intended for measuring water temperature in
heating applications, mounted in a well/pocket.
Accuracy See Appendix A: Tables A, D
STX122
The STX122 is primarily intended for pipe mounting without a separate pocket in
heating coils. The insert pipe is stainless steel. The sensor is delivered with a 2m
connecting cable, and has a R1/4” (DN 8) male thread fixing. As standard the sensor is
delivered with a separate R1/2” (DN 15) male thread reducing bush.
Accuracy See Appendix A: Table A
