Protect your critical assets with our cost-effective vibration monitoring system

Even a few hours’ unscheduled downtime in critical machinery can mean a great loss in production and man hours – not to mention the cost of repairs and spare parts when machinery is damaged.

Detect misalignment and bearing faults in rotating machinery

By monitoring vibrations in your rotating machinery, you get early warning of any misalignments or bearing faults.

The PCH vibration monitoring system protects your machinery 24/7. This helps prevent machine breakdowns and ensures continuity of production.

Local safety with built-in alarms

The slightest imbalance or misalignment can cause great damage to a machine and its bearings.

That is why our vibration monitors have a built-in alarm function which can detect any machine faults and warn the operator before they cause breakdowns.

You can even configure an automatic shut-down function for added local safety.

Collect trend data and perform FFT analyses

The PCH vibration monitors are the perfect addition to your condition monitoring or predictive maintenance program. You can collect scalar values and real-time time-stream / waveform recordings with the complementary PCH Vibration Studio software.

You can also transfer data to a SCADA or PLC solution using communication protocols like CAN Open, ModBus or ProfiNet, made available as 4-20 mA / 0-5V signals.

Store vibration data locally or online

Store the data locally with a PCH Datalogger module or our OPC server, or send it to a cloud database for remote access.

It is possible to make a fourier transformation (FFT) of time-recordings and identify vibration frequencies affecting your machine performance.

The analysis can be done on site or at a remote location after data transfer using our PCH EtherBridge.

Data can be treated locally or in the cloud. You retain ownership of your vibration data at all times.

PCH Vibration Monitors

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

Each monitor comes with complementary, Windows-based software for parameter set up, time wave streaming and offline FFT.

Several monitors also feature RS-485 communication.

PCH Link Concept

Combine any number of PCH monitors for a vibration monitoring solution customised to your requirements.

Our modular vibration monitoring system, the PCH Link Concept, is a simple, practical and cost-effective solution for small as well as large enterprises.

The Link Concept system comes with an Etherbridge module so you can store and analyse your vibration data online.
