Since PCH Engineering designed, developed and manufactured a range of affordable vibration sensors & vibration monitors featuring both analogue and digital accelerometers at our own production facility in Denmark, measuring and monitoring the vibration level of simple rotating machinery has become economically feasible,
The new Compact Range of PCH monitors can be compared to electronic watch-dogs or vibration switches. Most of our monitors are SIL 2 rated with MTTF(D), FIT, PFH(D) and DC diagnostic coverage numbers available. With a permanent real-time monitoring solution fitted on a machine, abnormal vibrations are detected as they occur. Custom defined alarm and danger relays reduce the need for human intervention, and scalar values of selected frequency ranges can be used for trending.
Price attractive alternative
For users who want to prevent their machines from damaging vibrations, e.g. vibrations coming from unbalance and misalignment at the most attractive prices.
Avoid unscheduled production stops
A breakown e.g. caused by bearing damage often occurs due to undetected unbalance or misalignment of a machine. Hence the machine runs for a very long time period with a much too high vibration level.
This is the most common reason for serious machine crashes and down time. Having an online vibration monitoring solution fitted, makes it possible to react in time and avoid unscheduled maintenance.
Collect trend data or perform FFT analysis
Scalar values and real-time time-stream / waveform recordings can be collected using the free PCH Vibration Studio software or data can be supplied to existing SCADA or PLC solution using standard communication protocols like CAN Open or MotBus, made available as 4-20 mA / 0-5V signals, or stored locally in a PCH Datalogger module. When convenient, waveforms can be FFT transformed and analysed on site or at a remote location.
Proven in use
Investing in a PCH Vibration Guard for a critical or expensive piece of machinery is a very wise decision. Often unexpected damages to machines lead to extra expenses to machine repairs, not to mention the further economic loss due to the production stop.
Today, PCH Engineering supply close to 20.000 machines a year with some degree of vibration monitoring, and we supply in volume for equipment like
- Centrifuges, Separators, Decanters & Purifiers
- Blowers, Fans & Pumps
- Waste Handling Systems
- Spray Driers
- Cooling Towers
- Food & Chemical Treatment units
- Cement Plants
It is possible to make stand-alone solutions as well as solutions for a number of machines. When it comes to data collection and analysis it can be done locally or data can be made available for remote access or integration cloud-based solutions.
