Industrial vibration accelerometers

Find a broad range of industrial accelerometers and vibration transducers from our own factory in Denmark and from our trusted partner, CTC.

The accelerometers are available in a selection of casings with varying sensitivity and operational temperature limits to cover a wide range of industrial applications from low-frequency structural monitoring to vibration monitoring of various rotating machinery.

 

Connect your accelerometers to a PCH vibration monitor

The accelerometers fit our range of PCH vibration monitors and various portable vibration instruments and data collectors. We also offer a selection of BNC outputs and junction boxes upon request.

 
Let us help you design the right monitoring solution:

IEPE accelerometers from CTC

In our range of integrated electronics piezo-electric accelerometers (IEPE accelerometers) from CTC, we are confident you will find a vibration transducer to fit your application.

CTC accelerometers are versatile, full-contact transducers typically used for measuring vibrations or shock. They are suitable for direct mounting on high- or low-frequency elements such as roller bearings, gearboxes and spinning blades and can be used either for permanent vibration monitoring or portable measuring.

Certified transducer sensitivity

We offer transducers with nominal sensitivities of 10/50/100/500 and 1000 mV/g. Each transducer comes with a calibration certificate documenting its exact sensitivity within the specified tolerance of ±10%. Even lower tolerances can be ordered.

 

Industrial accelerometers with life-time warranty

All CTC accelerometers come with a non-conditional life-time warranty. If something is not right, simply ship it back and you will get a new one for free!

 

Mounting of CTC transducers

Versions with either MIL connectors or M12 connectors are available.

PCH Engineering's MEMS accelerometers for low frequency monitoring

Designed for low frequency monitoring of wind turbines and other structural monitoring applications, these external, 1-, 2- and 3-axis MEMS accelerometers are manufactured at PCH Engineering’s own facilities in Denmark.

 

What the MEMS accelerometers measure

PCH MEMS accelerometers measure very low frequencies down to DC, typically in the 0-250 Hz or 0-1600 Hz range.

The accelerometers can measure velocity as well as acceleration as the signal conditioning is carried out by our PCH 1420 vibration monitor. Accelerometers for 100 mV/g and 300 mV/g are available.

 

Power supply for MEMS accelerometers

The PCH MEMS accelerometers are powered by the PCH 1420 vibration monitor or by a separate +24VDC external power supply.

 

MEMS accelerometer housing

All PCH MEMS accelerometers come in a sturdy stainless-steel housing with an M12 connector and can be mounted using either three M4 hexagonal socket screws or the integrated M8 threaded stud.

1-, 2-, and 3-axis MEMS accelerometers from PCH Engineering


 

Single axis MEMS accelerometers (CHB 1102/1115/1117/1128)

These external, 1-axis, low frequency accelerometers are intended for wind turbine and structural vibration monitoring.
  • 0.1-200 or 0.1-1000 Hz frequency response (-1dB)
  • -30 to + 60 °C temperature range
  • 84 mV/g or 260 mV/g sensitivity


 

Dual axis MEMS accelerometer (CHB 1101)

The dual direction accelerometer is often used for advanced nacelle monitoring in wind turbines with distributed pick-up points.
  • 0.1-100 Hz frequency response (-1dB)
  • -30 to + 60 °C temperature range
  • 260 mV/g sensitivity


 

Triaxial MEMS accelerometer (CHB 1110/1126)

This external, 3-axis accelerometer is compatible with most data acquisition systems or the PCH 1420 Vibration Monitor. In low frequency applications such as structural monitoring of buildings, antennae, cooling towers or test rigs, the CHB 1110/1126 triaxial accelerometer is the ideal cost-effective vibration monitoring solution.
  • 0-1600 Hz frequency response (+/-3 dB)
  • -30 to + 60 °C temperature range
  • 100 mV/g or 300 mV/g sensitivity




 


 

Cables and mounting hardware for accelerometers

We offer a range of cables and mounting hardware for your accelerometers. The cables come in various types and lengths and with a range of connectors depending on the job and the environment in which they are to be used.

You will also find a range of interconnection and junction boxes to help set up your monitoring solution.
