Copeland Comfort Control (Alco) 808361 Pressure Transmitter 0-18 Bar PT5B-18M

The Copeland Comfort Control (Alco) 808361 Pressure Transmitter is an electronic pressure-sensing component used to measure refrigerant pressure and convert into a proportional electrical signal for system control. It is installed on the pressure line where it monitors operating conditions and sends to the controller for regulation of compressors, fans, or electronic expansion valves. The 0-18 Bar PT5B-18M specification defines the pressure measurement range and model type ensuring accurate sensing across typical refrigeration operating pressures. In HVAC systems, it supports precise system control by improving load adaptation, enhancing energy efficiency, and maintaining stable operation.
