Application
The 1000 ohm Nickel temperature sensors are used in HVAC installations to measure
room, outside air, duct or liquid temperature. They can also be used to provide
changeover from heating to cooling, or vice versa.
They are designed for integration in terminal units such as fan coil or induction units.
The sensors can be installed either by the terminal unit manufacturer or on site.
