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.

5. Differential-pressure sensors, industry (DPI V.2 and DPI V.2+T)

General data

Fig. 67 DPI V.2 sensor

Technical overview The DPI V.2+T combined differential-pressure and temperature sensor (two-in-one) from Grundfos Direct Sensors™ is designed for industrial applications.

The capillary tube makes it possible to measure the differential pressure.

The DPI V.2+T sensor is fully compatible with aggressive liquids. The sensor is based on MEMS sensing technology in combination with the corrosion-resistant Silicoat® coating technology on the sensor chip.

This makes the DPI I+T sensor very robust and ideal for pump integration and monitoring in harsh environments.

M12 cable4-wire screened cable with M12 connector in the sensor end and open end in the equipment end. Use the cable for the industrial sensor series such as RPI, DPI and VFI.

Capillary tubeUse the capillary tube together with the DPI, DPI V.2 and DPI V.2+T to connect the sensor to the low-pressure side of the equipment.

The capillaries are available in copper and stainless steel as well as in various lengths.

AdapterUse the adapter together with the capillary tube. The adapter enables the connection of the tube to the system.

Adapter for Grundfos CR pumpsThis adapter is required when fitting the RPI, RPI+T or DPI V.2, DPI V.2+T on Grundfos CR pumps.

- An adapter is not required. An adapter is required if the sensor and coupling guard are in

direct contact. This will create unnecessary acoustic noise. An adapter is always required.

Snap-on cableCable with snap-on connection in the sensor end and different variants in the equipment end, such as open end, ferrules and various types of connectors.

Use the cable for the standard sensor series such as VFS, RPS and DPS.

The cable is available in various lengths, mainly 1.2 m and 2.9 m.
