Grundfos Direct Sensor™
1. Product introduction
This data booklet deals with Grundfos pressure
sensors.
TM04 5034 2409 - TM04 7865 2410
TM04 7866 2410 - TM05 4752 2512
Differential-pressure sensor
Grundfos pressure sensors
Three different types of pressure are used in pressure
measurement:
• Absolute pressure: the measured value is zeroreferenced against a vacuum.
• Relative pressure: the measured value is zeroreferenced against the ambient air pressure.
• Differential pressure: the measured value is the
difference between two pressures.
The Grundfos pressure sensor range contains relativeand differential-pressure sensors as well as relativeand differential-pressure sensors combined with
temperature sensors. The latter are able to measure
temperatures ranging from 0 to 100 °C (32 to 212 °F),
allowing the Grundfos sensors to be used for a wide
range of applications.
Relative-pressure sensor
The central part of a relative-pressure sensor is a
sensor chip which transforms the pressure into
electrical signals. The difference between the ambient
air pressure and the system pressure will cause the
sensor 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 relative-pressure sensor
combined with temperature sensor also transforms the
temperature of the medium into electrical signals.
A microprocessor calibrates, conditions and sends the
analog output signals. The pressure signals are
temperature-compensated and linearised for the
influence of temperature variations.
TM03 4055 1406
Fig. 1
The central part of a differential-pressure sensor is a
sensor 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, will cause the sensor 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 that include temperature measurement
also transform the temperature of the medium into
electrical signals.

affected by pressure on both sides
Sensor chip
The steady-state properties of silicon protect the
sensor chip against wear and tear. Lifelong nanocoating protection enables direct measurement (wetwet) in a cost-effective packaging for aggressive
media. 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 medium, Silicoat ® ensures protection of the
sensor chip from aggressive media (pH2 - pH11) at
temperatures up to 120 °C (248 °F) for the entire life of
the product.

The relative-pressure sensor, type RPI, from Grundfos
Direct Sensors™ is designed for industrial purposes
and to be mounted directly on the unit, for example a
pump.
The RPI sensors are fully compatible with wet,
aggressive media. They use MEMS sensing
technology in combination with the Silicoat® corrosionresistant coating technology on the sensor chip.
This makes the RPI sensors very robust and ideal for
pump integration and monitoring in harsh
environments.
The RPI+T sensor offers a two-in-one solution with an
addtional temperature measurement.
• RPI+T: pressure and temperature measurement in
one sensor (two-in-one solution)
• compatible with wet, aggressive media
• accurate, linearised and temperature-compensated
output signal
• RPI+T: quick temperature response (direct contact
with medium)
• cost-effective and robust design
• system solution with Grundfos pumps.

DPI sensor
Technical overview
The differential-pressure sensor, type DPI, from
Grundfos Direct Sensors™, is designed for industrial
purposes.
The DPI sensors are fully compatible with wet,
aggressive media. They use MEMS sensing
technology in combination with the corrosion-resistant
Silicoat® coating technology on the sensor chip.
This makes the DPI sensors very robust and ideal for
pump integration and monitoring in harsh
environments.
• Compatible with wet, aggressive media
• accurate, linearised and temperature-compensated
output signal
• cost-effective and robust design
• system solution with Grundfos pumps.
Approvals
• WRAS
• KTW
• ACS.

DPI V.2 sensor
Technical overview
The combined differential-pressure and temperature
sensor (two-in-one solution), type DPI V.2, from
Grundfos Direct Sensors™ is designed for industrial
purposes and to be mounted directly on the unit, for
example a pump.
The DPI V.2 is used together with a capillary tube in
order to measure the differential pressure between two
points of the system.
The DPI V.2 sensors are fully compatible with wet,
aggressive media. They use MEMS sensing
technology in combination with the Silicoat® corrosionresistant coating technology on the sensor chip.
This makes the DPI sensors very robust and ideal for
pump integration and monitoring in harsh
environments.
• Pressure and temperature measurement in one
sensor (two-in-one solution)
• compatible with wet, aggressive media
• accurate, linearised and temperature-compensated
output signal
• quick temperature response (direct contact with
medium)
• cost-effective and robust design
• system solution with Grundfos pumps.
Approvals
• WRAS
• KTW
• ACS.

Technical overview
The RPS sensor is a combined pressure and
temperature sensor (two-in-one solution) from
Grundfos Direct Sensors™.
The RPS sensors are fully compatible with wet,
aggressive media. They use MEMS sensing
technology in combination with the corrosion-resistant
Silicoat® coating technology on the sensor chip.

Sensor interface, SI 010 CNV
TM04 4882 2209
The sensor interface, type SI 010 CNV, from Grundfos
Direct Sensors™ is an external power supply, signal
amplifier and signal converter for Grundfos sensors,
standard variants (VFS, RPS, DPS).
SI 010 CNV has built-in precision resistors enabling
the sensor to send 4-20 mA, 1-5 V and 2-10 V output
signals.
SI 010 CNV should be used in applications where
sensors from the standard product range are used, but
the controller requires a 4-20 mA input signal.
Fig. 140 Sensor interface, SI 010 CNV
Specifications:
• Voltage range: 115-230 VAC ± 10 % or 24 VDC.
• Frequency: 50-60 Hz.
• Power consumption: max. 2.5 W.
• Ambient temperature: -20 to +50 °C (-4 to 122 °F).
• Enclosure class: IP20.
