Description
The Honeywell TR21-J Temperature Sensor that is used for HVAC systems. It uses a thermistor with a reference resistance of 20K at a reference temperature. This thermistor is used to show resistance change with changes in the temperature. The sensor sends this resistance data by LonWorks technology, which is a digital communication that is widely used in building automation systems. This makes it possible to interface and manage many equipments such as air handers, chillers, fan coil units and others. This sensor is effective in controlling temperature and improving the performance of a system, energy conservation, and comfort of a building.
