Temperature sensor NTC 100 K for solar heating controller SH-E01

Temperature sensor NTC 100 K for solar heating controller SH-E01

General			Solar heating controller type SH-E01 uses
			the differential temperature between two
			temperature sensors to control the transfer of
			heat energy from a Solar collector to a hot
			water storage tank.
			These temperature sensors are thermally
			sensitive semiconductor resistors which show
			a decrease in resistance as temperature
			increases. In this application the sensors are
			used in accordance with their zero-power
			characteristics.
			Sensor units consist of an NTC (negative
			temperature coefficient) 100 K resistance
			element which is then encapsulated in a
			sealed Copper tube.
			The sensor is adjusted to meet the tolerance
			requirements of BS EN 60751.
