JTF-5
Frost protection thermostat, capillary length 3 m, external setting
For protecting hot water heating registers against freezing. The device is intrinsically safe and has a sealable setpoint adjustment.
For temperature measurement of non-aggressive gases. The JZ-05/6M (metal) or JZ-05/6 K (plastic) mounting clamps must be used to clamp the capillary in front of the heating coil. The capillary is active along its entire length. The device responds when approx. 30 cm of capillary reaches the set scale value. Mounting clamps, immersion sleeves and protective coils are not included in the scope of delivery and must be ordered separately.
