Frost protection thermostat, capillary length 3m, external setting, 2-stage
For measuring the temperature of non-aggressive gases. The JTF-25 frost protection monitor has 2 switching outputs, which makes it possible to override the system before the danger point is reached. When fixing the capillary tube, mounting brackets JZ-05 / 6 M (metal) or JZ-05 / 6 K (plastic) should be used upstream of the heating coil. The capillary tube is active along its entire length. The device reacts when approx. 30 cm of the capillary tube reaches the adjusted scale value. Mounting brackets, immersion sleeves and protective coils are not included in the delivery and must be ordered separately. Hysteresis between the stages approx. 5 K.
