The Murphy Series 1501 instrument is a microprocessor-based alarm, shutdown and control system with tachometer/hourmeter function and can be configured to monitor applications such as air and gas compressors, natural gas refueling, and other industrial operations.
The 1501 annunciates in alphanumerica characters to describe the protective device that has signaled an alarm or caused equipment to shutdown. Information is called up and adjustments are made on a six-button keypad on the face of the unit. Configurations such as: Alarm or Shutdown Nomenclature, Preset Timers, and Tachometer Calibration can be made in the field.
The complete Series 1501 system consists of a head (monitor), sensor input terminal strip (two needed for 64 sensor models), 36 inch (914 mm) flat ribbon cable(s) for connecting the terminal block to the head/monitor, and a Class I, Div. 1, explosion-proof power supply.
