Johnson Controls A99BB-300 Temperature Sensor Silicon PVC 9.75' Cable -40°F To 212°F

The Johnson controls A99BB-300 Silicon thermostat sensor is a cost-effective solution for temperature measurement in HVAC applications. This sensor has a small probe made of stainless steel and it has a silicon thermistor. It works as a specific resistor, which varies its electrical resistance depending on temperature fluctuations. It is for surface mounting and comes equipped with a 9.75-foot PVC insulated cable with bare wire terminals for direct connection to HVAC controls. This is because when the temperature changes, the sensor sends an electrical signal along the connection so that the system can constantly provide comfort. The easy surface mount design makes it convenient to install and is therefore a convenient solution for temperature monitoring and control of the efficiency and comfort of a building.
