Measuring principle
The pressure transmitter operates based on a glass micro-fused piezoresistive sensing element. When pressure is applied, mechanical stress is transferred through the stainless-steel diaphragm to the sensing element. The resulting resistance change is detected by the internal electronic circuit and converted into a standardized electrical output proportional to the applied pressure.
This solid-state structure eliminates the need for oil filling, improving mechanical robustness and long-term reliability under harsh operating conditions.
