  • Page 9 3 Product description Fig. 2: Process pressure measurement CPT-2x Measuring system pres- Sensor element is the measuring cell with robust ceramic diaphragm. The process pressure deflects the ceramic diaphragm and causes a sure capacitance change in the measuring cell. This capacitance change is converted into an electrical signal and output as measured value via the output signal.
  • Page 10 3 Product description Pressure types The measuring cell design depends on the selected pressure type. Relative pressure: the measuring cell is open to the atmosphere. The ambient pressure is detected in the measuring cell and compen- sated. It thus has no influence on the measured value. Absolute pressure: the measuring cell contains vacuum and is encapsulated.

    4 Mounting Mounting General instructions Note: Process conditions For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter "Technical data" of the operating instructions or on the type label. Hence make sure before mounting that all parts of the instrument ex- posed to the process are suitable for the existing process conditions.
  • Page 15 4 Mounting Warning: The housing or the electrical connection may not be used for screw- ing in! Depending on the device version, tightening can cause dam- age, e. g. to the rotation mechanism of the housing. Vibrations If there is strong vibration at the mounting location, the instrument version with external housing should be used.
