PCH 1420 Vibration Monitor (4-Ch)

In the standard IEPE version, each vibration channel operates within 2 simultaneously running frequency bands.

The bands are configurable from 0.7 Hz up to 11.5 kHz and will typically monitor the 10-1000 Hz area (ISO 10816-3), as well as the high frequency area 2-10 kHz, where roller bearing resonances are detected.

PCH 1420 uses several bearing fault detectors simultaneously, in order to detect faults as early as possible.

Thus PCH 1420 offers both broadband high frequency monitoring, Envelope, Kurtosis and Crest factor for bearing fault detection.

All detectors are running simultaneously and are based upon inputs from up to 4 measuring points in real-time.

Vibration input channels -
PCH 1420 supports various vibration sensors, like IEPE, 3-wire API678 accelerometer, proximity probes, velocity sensors as well as PCH Low Frequency accelerometers.

Enhanced alarm functions -
In case an alarm limit is exceeded integrated alarm relays can inform the user via a connected rotor light, beeper, a control system or by directly shutting down the machine. PCH 1420 also delivers 4-20 mA signals relatively to the vibration level, which can be used for trending in the users control system.

PCH 1420 software interface -
The included user software PCH Vibration Studio can be used trending and for recording of 4 time waveform signals simultaneously (raw data) and for FFT analysis of the recorded data. Simply plug in the USB cable or connect a permanent RS-485 wire for remote access!

EN / ISO 13849-1 Functional Safety -
More features in PCH 1420 support Functional Safety requirements according to ISO 13849-1.

PCH 1420 Link Concept -
More modules can be connected to the PCH 1420 Vibration Monitor if needed. We offer the PCH EtherBridge for LAN/remote connection as well as for data logging and the PCH Relay Box for extra 12 isolated alarm relays.

More PCH expansion boxes are coming and creating the perfect Link Concept. You only pay for what you need, nothing more.
