Air temperature sensor SZT-2

SZT-2 sensed temperatures intended to control air temperature.

Used with electronic controllers ETR2-1550 and ETO2-4550. The temperature sensor itself is a 12 kΩ / 25 °C high-resistance NTC resistor (36 kΩ at 0 °C) housed on a printed circuit board inside a plastic, waterproof case.

The SZT-2 temperature sensor is mainly used to control the process of melting snow and ice in gutters and storm water drains in combination with electronic regulators ETO2-4550 and ETR2-1550.
