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.
