There are several types of pressure measurement. These include:
- Absolute: This sensor measures the pressure relative to perfect vacuum.
- Gauge: This sensor measures the pressure relative to atmospheric pressure. These are also referred to as relative pressure sensors.
- Vacuum: This sensor measures pressures below atmospheric pressure, but it may also be used to describe a sensor that measures absolute pressure relative to a vacuum
- Differential: This sensor measures the difference between two pressures, one connected to each side of the sensor.
- Sealed: This sensor is similar to a gauge pressure sensor, but it measures pressure relative to some fixed pressure rather than the ambient atmospheric pressure
Within the industrial world, sensor and transducer are often used interchangeably. A pressure sensor and pressure transducer are similar but have specific differences. A pressure sensor is any device that measures pressure and converts it to an electrical signal. Pressure sensors can be described with a 4-20 milliamps (mA) output signal and pressure transducers with a millivolt (mV) signal.
Pressure Sensors vs. Pressure Transducers
Trench Etched Resonant Pressure Sensors use a resonating silicon pressure-sensor which exploits the naturally occurring perfect elasticity of the single crystalline structure. With no imperfections, this new silicon sensing technology gives unprecedented levels of accuracy and stability radically enhancing performance. They offer an order of magnitude greater performance over current technologies to provide the highest accuracy and stability sensor available.
- High Quality
With over 40 years’ experience GE/Druck’s pressure sensors are trusted in hundreds of applications, from Aerospace and Subsea to Meteorology, Hydrology and a many other manufacturing processes. With the silicon-based, piezo resistive technology, their range of pressure sensors and transmitters give high-accuracy, excellent stability and reliable performance unbeaten in the field.
The unique TERPS (Trenched Etched Resonate Pressure) technology sensors give unprecedented levels of accuracy and performance far greater than the piezo resistive technology, up to 0.001% FS
They offer many applications including:
- Wellhead monitoring in the oil & gas industry
- Air data test systems and environmental control systems in the aerospace industry
- Sea bed mapping and steam gauging in the environmental research industry
- Many more
