PCB 682C05 Bearing Condition Transmitter Unit - Sensor power supply and vibration signal processing transmitter unit for implementing bearing monitoring based on PLC, DCS, or SCADA systems

• built-in sensor power supply (4 mA)
• connectable sensors: 1 ICP sensor (100 mV/g sensitivity)
• signal evaluation frequency ranges: vibration level: 10 Hz ... 1 kHz bearing fault: 1 kHz (5 kHz) ... 100 kHz
• signal output 2 pieces of 4...20 mA (vibration velocity and vibration acceleration, and buffered sensor signal (AC)
• selectable signal scaling (vibration velocity): peak or RMS value
• selectable measurement ranges: 5 g / 0.5 in/sec 10 g / 1.0 in/sec 20 g / 20 in/sec
• compact size (99 x 22.5 x 114.5 mm), mountable on standard DIN rail
• power supply requirement: 20...28 V DC

The PCB 682C05 device is primarily used for connecting industrial piezoelectric acceleration sensors with built-in charge amplifiers in ICP design to process control, PLC, DCS, and SCADA systems. The units enable existing systems to provide continuous, vibration-based bearing monitoring.

The device is available in single-channel version for receiving a 100 mV/g sensitivity ICP piezoelectric vibration acceleration sensor with built-in charge amplifier. The device provides sensor power supply.

The PCB 682C05 device outputs two 4...20 mA current signals: one for vibration level (vibration velocity, scaled as peak or RMS value), and one for bearing condition-proportional filtered vibration acceleration signal. The latter can have a selectable lower frequency limit of 1 kHz or 5 kHz.
