Due to its accuracy and high reliability, pressure measurement technology
in the process industry is one of the most versatile and robust measuring principles applied for pressure and level. It demonstrates its capabilities especially when things get difficult: in chemically aggressive media, in hygienic or hazardous areas, in applications with rapid temperature changes, heavy condensation or extreme pressures and temperatures.
Temperature or thermal shock resistance is a recurring issue for many pressure transmitters
with ceramic measuring cells, but not for VEGA's CERTEC® measuring cell − its special compensation capability provides an effective antidote to this particular vulnerability. An additional temperature sensor circuit on the rear of the diaphragm can detect even the slightest change in temperature and has thus solved this problem. This temperature value can even be used as a second output. But the ceramic-capacitive CERTEC® measuring cell, manufactured from special sapphire ceramic, can do much more: it is one of the most robust and resilient pressure measuring cells ever made.
In short: When the loads are enormous and the demands on the measuring cell are high, there are 7 good reasons for using pressure transmitters with ceramic measuring cells.
