Speed sensor signal conditioner 5534, 5544

These Velocity Signal Conditioners accept signals from machine casing mounted velocity sensors and produce a 4-20 mA current source output proportional to the measured variable. The detection circuit is responsive to true RMS vibration but the output may be scaled either to peak or RMS units. A green LED indicates sensor and cable integrity. In the event of sensor failure, the LED extinguishes and the output current is driven below 3.6 mA, thereby signaling a malfunction. A BNC connector gives access to the buffered input signal for local analysis. Optional features for either model include filters and galvanic isolation between input, output and power supply.
