With the ceramic pressure sensor SD-25 Suchy-Messtechnik offers an alternative to the conventional stainless-steel sensor elements. The sensor with internal diaphragm is suitable for measurements of gaseous and liquid non-crystallizing pres-sure mediums. The 200 g pressure sensor has an accurancy of 1 % from full scale value in ranges from 0…1,6 bar and 0…400 bar. Another advantage is the very short respond-time in ranges of ms only. The sensor has a very good linearity and a small hysterese. The measuring results are converted into current or tension signals (4…20 mA or 0…10 V) and can be shown by means of digital displays. Thanks to its good chemical reliability and the high resistance against wearing out, the sensor has a high long-therm stability and is unsensible to vibrations, shock and acceleration-influences. The range of possible measuring temperatures are from -40 up to +125 °C.
