PCB 682A15 vibration velocity transmitter unit - Sensor power supply and vibration signal processing transmitter unit for implementing machine monitoring based on PLC, DCS, or SCADA systems

• built-in sensor power supply (4 mA)
• connectable sensors: ICP sensors (with 100 mV/g sensitivity)
• frequency range 3.5 Hz ... 10 kHz
• measurement range: 0 ... 25.4 mm/s (RMS)
• output signal 4...20 mA DC vibration velocity + buffered sensor signal (AC)
• signal processing: single integration
• signal scaling: RMS
• compact size (99 x 22 x 114.5 mm), mountable on standard DIN rail
• power supply requirement: 23 ... 25 V DC

The PCB 682A15 device is primarily used for connecting common ICP-type (with built-in charge amplifier) piezoelectric industrial acceleration sensors to process control, PLC, DCS, and SCADA systems. By using this unit, existing systems can provide continuous vibration-based machine monitoring.

The device is designed in a single-channel version to accommodate one 100 mV/g sensitivity ICP-type (with built-in charge amplifier) piezoelectric vibration acceleration sensor. The device provides sensor power supply.

The PCB 682A15 device provides a standard 4...20 mA vibration velocity current signal and a buffered (AC) vibration sensor signal. The frequency limit and signal scaling are not adjustable.
