Thin film deposition surface layer, active strain gauge bridge circuit, pressure measurement device with signal output.
DMP334 Hydraulic Pressure Transducer for Very High Pressures - DMP 334 is a high range pressure transducer designed for measuring hydraulic pressures up to 2200 bar (32,000 psi) .
Thin film deposition is the process of generating a very thin coating of material onto another thicker substrate material. Thin film layers of different materials are built up using masking techniques to create electronic devices on the surface of the base material. This leads to a highly stable miniature electronic component which retains the mechanical properties of the substrate material.
A strain gauge is a device for measuring an applied force. The electrical resistance or impedance of a strain gauge will change when a strain gauge element is stretched or compressed. Strain gauges are incorporated into electrical circuits designed to exploit the sensitivity of the strain gauge, so that the resulting change in electrical resistance is converted into a measurable voltage which can be sent to other electronics for further processing.
A pressure sensor is a device which measures or detects the pressure of a liquid or gas and sends it as a signal of a specific type and format, which is recognised by connected monitoring and control instrumentation.
