A vibration sensor (also called vibration sensor) of modern design consists of a piezoceramic which is preloaded by a so-called seismic mass. Due to the vibrations, the mass hits the piezoceramic, similar to the hammer in an electric lighter. The latter thereby releases a charge which is converted into a voltage signal by a corresponding charge amplifier. All vibration sensors from our company, with the exception of some high temperature models, have an integrated charge amplifier. This makes the use of the vibration sensors particularly easy.
The main optical distinguishing feature of the vibration sensors is the different size. The design of the vibration sensors, however, is mainly related to the sensitivity and the associated frequency band. Put simply, low-frequency transducers are more sensitive and have a much larger housing than, for example, miniature sensors used for high-frequency applications. Industrial vibration sensors form an attractive average value: they have a sensitivity of 100 mV/g and a typical frequency band of 1 Hz to 8000 Hz.
At the lower end of the scale you will find so-called seismic vibration sensors to measure vibration. Our reference transducer 731A has a sensitivity of 10 V/g with a typical frequency response of 0.05 Hz to 500 Hz. At the other end, we supply vibration sensors for shock applications, which have a measuring range of up to 70,000 g with a frequency response well above 15,000 Hz.
All vibration sensors from our company have a stainless steel housing and are therefore suitable for rough industrial use. The standard connectors have a protection degree of IP67, but submersible vibration sensors are also available for use in several 100 m water depth.
In contrast to our force or pressure sensors, vibration sensors with integrated charge amplifier require a constant current supply. This means that the supply electronics supply the supply voltage via a constant current diode over a constant supply current between 2 and 5 mA. Our measuring amplifiers for vibration sensors VIB-KS are optimally equipped for this task and can supply the effective value or limit contacts in addition to the peak-to-peak acceleration. Vibration measurement made easy.

Seismic Instrumentation
Earthquakes can not be forecasted or predicted. The primary damages at buildings, plants and infrastructure, and especially secondary damages caused by fire, explosion and pollution are a high risk for human beings and environment.
The risk increases by earthquake hazard, density of population and industry as well by the vulnerability of buildings, lifelines and industry.
Higher risk industry and lifelines get a basic design including the estimated additional earthquake load of the location. This design is based on standards such as the German KTA 2201, the European Code 8, the US Regulatory Guide or the Uniform Building Code.
BARTEC SYSCOM`s seismic instrumentation measures continuously the vibration level at the sensor location and provides alarms if limiting values get exceeded. Based on these alarms immediate inspections can be initiated or high risk processes can get shut down. The automatically performed analyses compares design with measured values and allows further decisions.
A mechanical vibrating system gets forced to vibrate on its resonance frequency by means of piezo electric crystals. When the vibrating blade gets covered by the material to be detected the vibration stops. This is sensed by an electronic circuit which forces a binary output to switch. When the blade gets uncovered the vibration restarts and the output switches back.
The vibration technique has got many advantages over alternative level sensing technologies.
- unaffected by environmental changes e.g. temperature, pressure, humidity
- unaffected by material changes
- unaffected by dust clouds and agitation
- maximum versatility
- no calibration required
- no maintenance required: the vibration has a self cleaning effect
- highest performance and durability: no moving parts, no wear-out

Since many years already PTL Hermann is specialized in the development and production of vibrating level switches for bulk solids. These products are used for detecting the presence or absence of powdered or granular material that is stored in all kinds of silos, hoppers and containers. Special models for interface detection are available, e.g. to detect sand that has settled in water.
The unique, patented single rod designs of our instruments make them work perfectly and reliably even at critical applications where conventional products cause problems due to bridge building, material build-up or rat holing.
