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
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.
