Our SIL 2 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. Most of our monitors are SIL 2 rated with MTTF(D), FIT, PFH(D) and DC diagnostic coverage numbers available.

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 1072 Vibration Monitor features:
  • 1 vibration input channel (accelerometer, proximity probes or velocity probes)
  • 2 relays and a 4-20 mA output.
  • Redundant Safety Relay (SIL 2)
  • Configurable alarm levels and delay times
  • Offline FFT analysis

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 1073 Vibration Monitor features:
  • 1 vibration input channel (accelerometer, proximity probes or velocity probes)
  • 4 relays and two 4-20 mA output.
  • Redundant Safety Relay (SIL 2)
  • Configurable alarm levels and delay times
  • Offline FFT analysis

PCH 1008 Vibration Monitor (2-Ch)

The PCH 1008 is a digital multipurpose monitor with 2 input channels for IEPE or 3-wire API678 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 for CCLD/IEPE and Charge pC/ms-2
  • 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
  • Excellent replacement part for PCH 1014 and WB-1140 vibration monitor
  • 85-260 VAC power supply

PCH 1420 Vibration Monitor (4-Ch)

PCH 1420 operates with 2 simultaneously running frequency bands and 4 vibration input channels. This vibration monitor has a frequency range from 0.7 Hz to 11.5 kHz and will typically monitor the 10-1000 Hz area (ISO 10816-3), and the high-frequency area 2-10 kHz.

In order to detect faults ahead of time, PCH 1420 uses several bearing faults detectors simultaneously. It offers broadband high-frequency monitoring, Envelope, Kurtosis and Crest factor for fault detection.

The monitor includes application software PCH Vibration Studio which can record up to 4 times waveform signals and perform a FFT analysis of the recording data. 
PCH 1420 Vibration Monitor features:
  • Supports 4 vibration input channels (accelerometer, proximity probes or/and velocity probes)
  • 4 configurable outputs, relay or 4-20 mA
  • Redundant Safety Relay (SIL 2)
  • Configurable alarm levels and delay times
  • Offline FFT analysis
