The Digital Monitor Model-2590C receives a 4-20mA signal from the vibration converter,scales it into a vibration converter scales it into a vibration value for digital display and allows the vibration to be monitored by using a 2-high limit position alarm contact output. As an operating power supply for vibration converter is incorporated to make installation easier.
