The PTM-M series microelectronic pressure transmitters have optimum metrological and performance characteristics such as stability, reproducibility and noise immunity of the output signal, achieved by using a monocrystalline silicon sensing element on a sapphire membrane and a specialised electronic circuit with a high degree of integration and digital signal processing.
The high overload capacity of the transducers is achieved by using a double-layer sapphire-titanium membrane with monocrystalline silicon strain gauges ("silicon-on-sapphire technology"). The monocrystalline sapphire membrane is an ideal elastic element and, when combined with titanium, becomes a leader in terms of deformation.
The high degree of reliability of the sensing element and electronic circuitry does not require correction of the output range during operation.
- digital correction of the initial value of the output signal;...
