Principles of Good Measurement: Pressure Sensor MEMS

Why are Pressure Sensor MEMS important?

 

Over the last two decades, the pressure sensor MEMS (MicroElectroMechanical Systems) industry has made continuous improvements.  This continuous improvement is borne from the demanding requirements of tens of thousands of hydrostatic pressure based, level installations. In these applications, linearity and accuracy have to perform throughout the measuring range and a sensors’ performance is constantly monitored against content and level readings.  These pressure controls also have a range of approvals and designs for chemical, marine, food and pharmaceuticals available.

 

How do Pressure Controls Work?

 

The pressure measuring cell is the heart of the pressure transmitter converting the pressure into an electrical signal. This pressure dependent signal is converted by the integrated electronics into a standardized output signal. Different sensors are used for pressure measurement. The ceramic cells have the advantages of excellent long term stability with high overload resistance. The metal cells cover higher measuring ranges and use stainless steel as diaphragm material.

 

Where can I use Pressure Sensor MEMS? 

You can use Pressure Sensor MEMS in almost all pressure and vacuum applications. They can mount in any orientation with a wide range of process fittings to get connected to your process. High temperature, high resistance, gauge and absolute transmitters are available, across all ranges complimented with special ranges of (chemical) seals, fittings and materials.
