Our Monitors Keep Your Machines Operational

The monitors measure the condition of a machine 24 hours a day, 365 days a year. The built in alarm function secures early knowledge of all machine faults e.g. imbalances or misalignment. This allows you to handle problems before they cause breakdowns.

Therefore, you can assure operational continuity of your production and avoid unplanned machinery downtime, material costs, etc.

Standard Vibration Monitors

PCH 1072 Vibration Monitor

The PCH 1072 is the new generation of high quality low cost vibration monitors, which can be used in many rotating machine applications. The standard version is a 1 channels monitor with a frequency range from 0,7Hz to 1kHz. It offers user selectable filters and selection between acceleration, velocity or displacement.

The monitor is prepared for DIN rail installation or can be build into an IP67 casing.

The monitor includes Windows based software for parameter set up, time waveform streaming. For online and off line FFT. Can be connected to RS485 net.

PCH 1073 Vibration Monitor

The PCH 1073 is the new generation of high quality low cost vibration monitors, which can be used for surveillance of vibration levels in machinery and detecting unbalance and bearing faults.

The monitor operates within 2 simultaneously running frequency bands configurable 0.7Hz to 11.5 kHz. A primary low-frequency band monitors vibrations according to DIN/ISO 10816. A second multi purpose band offers detectors as RMS, Envelope, Crest factor and Kurtosis, and is ideal for condition monitoring of roller bearings.

It is possible from one transducer point to monitor both unbalance and bearing failure simultaneously.

The monitor includes windows based software for parameter set up, time wave streaming and off line FFT. Several monitors can be connected by a RS-485 net.

PCH 1008 Vibration Monitor (2-Ch)

The PCH 1008 is a digital multipurpose monitor with 2 input channels for IEPE or 3-wire accelerometers, configurable alarm levels, 4-20 mA outputs and delivered in an IP67 casing.

Each input channel can be configured with filter ranges from 1 Hz up to 10 kHz and supports both acceleration, velocity and displacment measuring units. This vibration monitor is a highly ruggidized measuring device for direct installation in the toughest industrial enviroments.

PCH 1008 Vibration Monitor features:
  • 2 vibration input channels
  • 1 Hz - 10 kHz filter ranges
  • True RMS, Peak or Peak-to-Peak detectors
  • Acceleration, velocity or displacement measuring units
  • 4 isolated 4-20 mA outputs
  • 4 potential free 240V alarm relays
  • 2 buffered unconditioned AC signals for signal analysis
  • ModBus over RS485
  • 85-260 VAC power supply

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.

PCH 1420 Vibration Monitor features:
  • 4 vibration input channels
  • 2 process input channels
  • 4 configurable outputs, relay or 4-20 mA
  • Redundant Safety Relay
  • User defined bandpass filters from 0.7 Hz up to 11500 Hz
  • Bearing fault detectors, Envelope, Crest and Kurtosis
  • Change alarm levels and delay times
  • Time waveform recording of vibration sequence from 4 channels simultaneously
  • Offline FFT analysis
  • Connection to several monitors on bus system
  • USB/RS 485 serial connection
  • ModBus TCP over PCH EtherBridge
  • Safety level SIL-2 rated and GOST-R certificate

The monitor is ideal for OEMs as well, where individual solutions can be offered.
