Ceramic Cell Advantages & Features

Up to 80X Overpressure Rating
As a result of the extremely sensitive and repeatable nature of the Certec ceramic cell, the diaphragm is able to withstand extreme overpressures without deforming or shifting the zero point.

Diaphragm will not deform or crack with most high pressure wash streams
The diaphragm will withstand pressures on the wash stream of up to 80 times its pressure rating. Most other pressure cells, such as piezoelectric or strain gauge, will only withstand an overpressure of 2-5 times its pressure rating.

Diaphragm will withstand most mechanical shocks
There are two possible states of the Certec measuring cell: working and fractured. Most mechanical shocks will not damage the diaphragm.

  • Diaphragm will perform and not be damaged in vacuum service
  • Completely Dry Cell - No Fill Fluid
  • No fluids to leak and contaminate sterile or high purity processes
  • Due to mechanical isolation of the body from the cell, no pressure is placed on the ceramic cell due to the expansion and contraction of the sensor body
This eliminates temperature drift as the thermal expansion and contraction of other parts of the cell does not impact the measurement area.

Zero Point Stability in Pressure Shocks
The ceramic cell is able to withstand water hammer, pump pulsation and other pressure shocks and not require recalibration to reset the zero point.

Excellent Long Term Stability
There is no aging process with the ceramic diaphragm as there is with metal. Therefore, the diaphragm remains constant and only sees minimal changes with time and pressure cycles.

Self Diagnostic Capability
The ceramic cell instantly recognizes the change in capacitance if the diaphragm is damaged and gives immediate notification of damage to the cell.
