Pressure Operated Pump Transmitter Model: RFM4300-PT Transmitter Description The pressure operated pump transmitter is designed to detect if a pump is in a plugged or blow through condition. The transmitter also has a cycle counter option to help with preventative maintenance. Information collected allows for condensate return calculations and trending of capacities of the pump trap. The pressure operated pump transmitter works with any mechanical pump.
