Schneider Electric (Barber Colman) 2252-251 0/100F Temp.Transmitter,20'Avg

The Schneider Electric Barber Colman 2252-251 is a temperature transmitter intended for use in HVAC systems. It works by translating temperature values between 0 and 100 degrees Fahrenheit into an equivalent electrical signal. The building automation systems or controllers receive this signal and can use it to monitor and control temperature in a variety of applications, such as air conditioning, heating, and ventilation systems. The product name 20'Avg stands for the transmitter's average time constant. In other words, it provides a more steady signal for improved HVAC system control by averaging the temperature measured over the previous 20 minutes. This helps to filter out sudden variations.
