NIBE Temperature Sensor NTC 10kΩ

Description

This NTC 10 kΩ temperature sensor is developed for accurate temperature registration in modern heating systems and heat pump systems from Nibe. The sensor is often referred to as, for example, BT25 (external supply line sensor) and ensures that the control system continuously receives correct measurement values. This contributes to even indoor comfort, optimal energy use and stable operation of the heat pump all year round.

The sensor body is encapsulated in a durable metal sleeve that provides good heat transfer and protection against moisture and wear. The two connection cables facilitate installation directly to the terminal block in the heat pump or in the control and regulation module.
