126632-01 Monitoring capability:
Bently 990 and 991 single channel shaft vibration and displacement transmitters can proportionally convert vibration signals into 4 to 20mA signals, providing data for the control system PLC or DCS of the equipment.
Suitable for equipment powered by dual wire circuits, it can accept input signals from Bentley 3300 XL proximity eddy current sensor probes and their matching extension cables.
126632-01 Signal adjustment:
The transmitter can adjust the signal to the corresponding vibration peak unit and proportionally convert this value into an industrial standard input signal of 4 to 20mA, facilitating the protection, alarm, and logic control of the unit.
126632-01 Compatibility:
Compatible with the Bently 3300 XL NSv proximity probe, the sensor can be installed in narrow areas of centrifugal air compressors.
126632-01 Technical specifications:
Power supply: The transmitter terminal requires an input of+12 to+35 Vdc.
