The transmitter consists of a sensor hausing in stainless steel and a ceramic membrane. Resistors are applied to the membrane in thick film technology. The pressure affecting the membrane results in a change of resistance value depending on the bending of the membrane and this is transferred by means of the built-in electronics to a proportional output signal. The construction with only one moving part and a direct signal from the membrane gives a high level of accuracy and a short response time. The properties of the membrane also ensure good stability over time and low temperature dependency.
