Siemens Combustion 7MF-421-030 Pressurer Sensor 0-30 PSI 4-20mA

The Siemens Combustion 7MF-421-030 Pressure Sensor designed for monitoring the pressure in HVAC systems to provide better performance and safety. It is designed for the 0-30 PSI range and provides stable analog output. This pressure sensor measures the physical pressure and provides an electrical signal of 4-20 milli amperes that can easily be regulated by the system. It also monitors pressure levels and sends the data to the HVAC control system to enhance its performance. It is installed in chillers, boilers and air handling units to increase the system's dependability, decrease energy consumption and facilitate preventive maintenance by detecting faults at an early stage and maintaining constant pressure.
