Pressure Sensors

  • Group of sensors
  • Unik 5000

Pressure sensors are designed to measure the pressure of gases or liquids. They usually act as a transducer, generating an analogue electrical signal by converting pressure. They are used for control and monitoring in a variety of applications including: automotive, bio-medical instrumentation, aviation, and the marine industry.
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

Pressure Sensors vs. Pressure Transducers

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.


Trench Etched Resonant Pressure Sensors (TERPS) 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. TERPS offer an order of magnitude greater performance over current technologies to provide the highest accuracy and stability sensor available.


  • High quality
  • Reliability
  • Accuracy
  • Configurable
As pressure is defined as force over a unit of area, there are a number of ways to articulate pressure readings depending upon the unit of force and the unit of area. Most commonly, we will see PSI (pounds per square inch) or bar. Other units of measure include kg/cm2, inH2O, mmHg, Pa, and many others. With the GE/Druck pressure sensors, you just choose which unit of measure you need.
With over 40 years of experience, GE/Druck’s pressure sensors are trusted in hundreds of applications, from aerospace and subsea to meteorology, hydrology, and 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
