Vibration/Temperature Transmitter Monitors Industrial Machines

Specifically designed to monitor industrial machinery, the Model 972 solid-state, loop-powered sensor and transmitter continuously measures vibration and temperature and transmits data directly to a PLC. The component provides level monitoring, alarm and machinery shutdown capabilities. Two isolated 4 mA to 20 mA outputs are provided that are proportional to vibration and temperature levels. The vibration output, expressed as velocity, is pre-set at the factory for ranges of 0 to 1, 0 to 2, and 0 to 5 in./s. Measurements are made over a frequency range from 5 Hz to 2 kHz and over an operating temperature range from -20°C to 85°C. The temperature sensor employs a compensated RTD that is calibrated from 0°C to 100°C. The sensors are case isolated and accessed via a four-pin connector.
