Often the requirements for pressure sensors are very challenging because in most cases they serve in sensitive, tricky and critical positions subject to demanding specifications
Especially for those applications the miniature pressure sensors series 8111/8112 from burster have been designed. Thanks to their minimal dimensions the pressure sensors can be used in almost every branch of engineering. Suitable for both gaseous and liquid media, they can be fitted in any orientation, and used for both static and dynamic measurements. The sensors are chiefly used in the fields of tool and gear making, precision mechanics, aeronautical and space engineering but also in medical technology or food processing. The miniature pressure sensors are equipped with a flush mounted diaphragm from diameter 3.6 mm with connecting M5 assembly thread. Thus they can be easily mounted and tightened with a sealing ring. The light weight of the sensors can be fully neglected within their surrounding struc-ture. Their media touching parts as well as the housing are made of stainless steel or titan. Operat-ing temperatures up to +200 °C are possible as well as down to -75 °C. Measuring ranges are available from 0…2 bar to 0…350 bar. The single components of the miniature pressure sensors are bonded in a laser welding process whereas the sensors are thus designed that the distorting forces arising in the sensor housing are decoupled from the measuring membrane. This results in stable measuring values and a high accuracy. These qualities render the little all-rounders suitable for many trade branches. Representing all those simply the delicate food processing industry with its large number of concession regulations shall be mentioned here. The food industry not only focuses on the quality of the used raw materials but also on their high-quality processing. In the brewery industry i.e. burster miniature pressure sensors are used to control the exact pressure within bottling plants - directly on the spot and si-multaneously with the closure of each bottle.
