High performance industrial accelerometers

06 July 2020

Condition Monitoring specialist Sensonics has been developing industrial accelerometers for over 40 years and has earned a reputation for high performance. Specifically, on applications where low noise is crucial, Sensonics accelerometers have proven to excel.

Condition monitoring on critical machinery can involve complex algorithms, extracting fault vibration frequencies from a spectrum of signals with early detection being a key requirement. As a result of their experience in the design and manufacture of piezo-electric seismometers over many years for seismic monitoring systems, Sensonics have unparalleled expertise in understanding the performance criteria for accelerometers used at frequencies. These piezo-electric seismometers provide very high output of up to 50V/g, measuring low frequencies down to 0.1Hz with an ultra-low noise floor.

Initially developed by Sensonics in 1983, the QZ/U piezo-electric seismometer is the forerunner of their highly successful SP4 range of seismometers for measuring ground borne vibrations, structural vibration, earthquakes and other seismic measurements. Today, this unmatched experience in understanding and applying piezo-electric seismometer technology underpins the success of Sensonics range of ‘best-in-class’ superior noise performance PZS Industrial Accelerometers which are ideal for industrial machine condition monitoring applications.

The PZS range of low-noise accelerometers are an important part of the Sensonics range of industry proven transducers that also includes PZV, PZDC and VEL/G velocity vibration sensors, XPR eddy current proximity probes, CS capacitive air gap sensors and a wide range of LVDT displacement transducers. This extensive range means there is probably a solution for most vibration, position and shaft speed measurement applications. Specifically they are ideal for monitoring pumps, fans, motors, centrifuges, gearboxes, compressors and process equipment.

Many of the transducers have variants which are suitable for harsh or challenging applications including low frequency, high temperature, submersible, high pressure, radiation and intrinsically safe certifications. These include ATEX / IECEx / PESO for hazardous areas where potentially explosive dusts or gases prevail.

With a wide range of industry standard mechanical formats, output signals and power supply requirements, as well as simplified 4-20mA process output solutions, Sensonics are likely to have the right solution either for a new application or for the replacement of unreliable or obsolete equipment. Furthermore, if we don’t have an existing solution we can offer a bespoke design service.  ENDS
