DMP 331 Pressure Transmitter: High Overpressure Tolerance with Calibration Integrity #
Introduction: #
The DMP 331 pressure transmitter incorporates a silicon pressure sensor and a sensitive stainless steel convoluted diaphragm to protect it from the measured media. It utilizes an internal oil fill to transfer pressure to the silicon chip, ensuring accurate measurements. One remarkable feature is its ability to withstand high overpressures while maintaining factory calibration. For instance, the 1 bar absolute capsule can handle up to 5 bar overpressure without any offset shift.
Conclusion: #
The DMP 331 pressure transmitter sets a new standard for pressure measurement. With its silicon pressure sensor, stainless steel convoluted diaphragm, and internal oil fill, it achieves exceptional overpressure resistance while preserving calibration accuracy. This makes it an ideal choice for applications requiring reliable and accurate pressure measurement, even in scenarios with sudden pressure spikes or system malfunctions.
