2. Product introduction
This data booklet describes these Grundfos products:
• industrial relative- and differential-pressure sensors
• standard relative- and differential-pressure sensors.
Fig. 1 Grundfos pressure sensors
Three different types of pressure are used in pressure measurement:
• Absolute pressure: the measured value is zero-referenced against vacuum.
• Relative pressure: the measured value is zero-referenced against the ambient pressure.
• Differential pressure: the measured value is the difference between two pressures.
The Grundfos pressure sensor ranges contain relative- and differential-pressure sensors as well as relative- and differential-pressure sensors combined with temperature measurement capable of measuring temperatures from 0 to 100 °C (32 to 212 °F). This makes Grundfos sensors suitable for a wide range of applications.
Relative-pressure sensor The central part of a relative-pressure sensor is a chip which transforms the pressure into electrical signals. The difference between the ambient air pressure and the system pressure causes the chip to warp which is registered as a change of resistance in the strain gauges of a Wheatstone bridge. The change in resistance is converted into an analog output signal. The sensors incorporating temperature measurement also transform the temperature of the liquid into electrical signals.
The signals are linearised and compensated for the influence of temperature variations.
Differential-pressure sensor The central part of a differential-pressure sensor is a chip which transforms the differential pressure into electrical signals. The difference between the two system pressures on either side of the chip, called the differential pressure, causes the chip to warp. This is registered as a change of resistance in the strain gauges of a Wheatstone bridge. The change in resistance is converted into an analog output signal. The sensors incorporating temperature measurement also transform the temperature of the liquid into electrical signals.
Fig. 2 Schematic view of how the chip is affected by pressure on both sides
Sensor chipThe steady-state properties of silicon protect the chip against wear and tear. Lifelong nano-coating protection enables direct measurement (wet-wet) in a cost-effective packaging for aggressive liquids. The secret is a metal-glass alloy coating, Silicoat®, which is extremely resistant to corrosion. Compared to conventional sensor technologies, which encapsulate the unprotected measuring cell to protect it from the liquid, Silicoat® ensures protection of the chip from aggressive liquids (pH2 - pH11) at temperatures up to 120 °C (248 °F) through the entire life of the product.
