Compact Vibration Monitors Protect Your Machine 24/7

Did you think that vibration monitoring was only for complex, costly machinery?

Think again.

With PCH Engineering’s affordable range of compact vibration monitors with built-in accelerometers, you can measure and monitor the vibration level of simple rotating machinery without blowing your budget.

Let us explain.



 

Even simple machine damage can be costly

It used to be that monitoring the vibrations in simple machinery required complex, expensive monitoring solutions, making the investment in such asset protection unprofitable.

Instead, asset owners were forced to rely on manual monitoring and frequent maintenance or run the risk of machine damage.

And that, as any asset owner knows, can turn out to be equally unprofitable.

 
While simple rotating machinery may be easily repaired or replaced when damaged, the unscheduled maintenance and production stop that result from machine damage and breakdowns can be a costly affair.

Even more so if the machine is critical to production, as waiting for repairs or a replacement can cost plant owners dearly in lost production time.

At PCH Engineering, we wanted to change that. This is what we came up with:



 

The PCH Compact range – your affordable electronic watch dog

Think of PCH’s compact vibration monitors as electronic watch dogs or vibration switches protecting your machinery from damage and breakdowns:

The compact vibration monitors are a permanent, real-time monitoring solution with built-in sensors, which can be retrofitted to your machines, detecting abnormal vibrations 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.

 
And the most important part?

This range comes at a price that makes it a sensible investment, even for owners of simple rotating machinery.




 

Cost-effective vibration monitors made in Denmark

The compact range of affordable vibration monitors feature internal analogue as well as digital accelerometers, all of which are designed, developed and manufactured at PCH Engineering’s production facility in Denmark.

The PCH Compact Range forms a cost-effective alternative to more complex monitoring solutions for machine owners who wish to protect their simple, rotating machinery from damage and avoid unscheduled production stops.




 

Collect trend data or perform FFT analyses

Scalar values and real-time time-stream / waveform recordings can be collected using the free PCH Vibration Studio software.

Trend data can also be supplied to existing SCADA or PLC solutions using standard communication protocols like ModBus, TCP, RTU or OPC UA. These data can be 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 remotely.




 

SIL 2 Rated Vibration Monitors

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





 

ATEX Certified Vibration Monitors

Our range of ATEX and IECEx certified vibration monitors (PCH 1275 and PCH 1277) offer vibration monitoring solutions for machines in ATEX zones 1 and 21.




 

Vibration Monitors for The Eurasian Economic Union (EAC)

We offer versions of PCH 1275 and PCH 1277 that are EAC certified for the Eurasian marked (Russia, Belarus, Kazakhstan, Armenia, and Kyrgyzstan).

And how do we know the compact vibration monitors will work for your machine?

Here is how:

PCH Compact Range

PCH 1220 Electronic Vibration Switch

Are you looking for an electronic vibration switch with just one relay and no 4-20 mA output?

The PCH 1220 is a low-cost solution for a basic protection application.

 
PCH 1220 constantly monitors the machine vibration within a 10-1000 Hz (ISO 10816-3/20816-3) frequency band and compares the value to the preset alarm threshold.

You can use the PCH 1220 on fans, pumps and blowers where you need a digital alarm input, but can do without a 4-20 mA reading. The vibration alarm is preset at delivery, simplifying the installation.

The sensor is supplied in stainless steel 1.405 housing with an integrated M8 mounting stud and a M12 top exit connector.


 
PCH 1220 measuring parameter:
  • Velocity in mm/s
  • Frequency range: 10 to 1000 Hz (DIN/ISO 10816-3/20816-3)
  • Alarm level in mm/s pre-set to individual requirements
  • Alarm relay with delay time
  • Status indicator through LED on the monitor
  • 4-pin M12 connector

 


 

PCH 1232 Vibration Guard (Modbus RTU)

Modbus RTU vibration sensorThis vibration monitor uses several narrow filter bands to enhance the vibration monitoring for condition monitoring purposes. Lower vibration amplitudes are more easily and more thoroughly tracked and you get more data on the condition of your machines, allowing you to schedule maintenance at the exact time that you need it.

The PCH 1232 vibration sensor offers full integration with Modbus RTU in a distributed RS 485 network.
 

PCH 1232 Vibration Guard features:

  • Measuring parameter: velocity mm/s or acceleration m/s², RMS or Peak
  • Frequency ranges: 10 to 1000 Hz or selectable HP/LP filters for narrow bands
  • Up to 4 configurable filter bands with scalar values
  • 2 alarm levels with individual delay times per filter band
  • 2 analog DC outputs 4-20 mA and 2 alarm relays
  • RS-485 and Modbus RTU communication
  • Setup by PCH user software PCH Vibration Studio through USB or RS-485
  • Self-test function can be activated externally
     


 

PCH 1270/1272 Vibration Guard (SIL 2)

The PCH1270 and PCH1272 are ideal as part of the safety chain for dangerous machinery when high accuracy and fast response time are important.

Our PCH 1270/1272 Compact Vibration Guards compare the actual vibration levels with the internal thresholds 10 times per second, making it suitable for early warning or even for emergency shutdown of your machinery.

You have a choice of either standard ISO 10816-3/20816-3 filter ranges (2/10-1000 Hz) or customised filter ranges. 

 

PCH 1270/1272 Vibration Guard features:

  • Measuring parameter: velocity mm/s or acceleration m/s²
  • Frequency range: 10 to 1000 Hz or 1 to 30/300 Hz
  • 2 alarm levels with individual delay times and 2 alarm relays
  • Analog DC output RMS 4-20 mA, proportional to 0-100 %
  • Measuring range selectable: 10/20/50/100 mm/s or m/s² rms
  • Self-test function can be activated externally
  • Safety level SIL 2 rated, GOST-R certificate, ETL listed upon request
  • RS-485 version available as PCH 1272 for communication with PCH user software
