Grundfos Direct Sensor™
Introduction
Pressure transmitter
1. Pressure transmitter
pressure, will cause the sensor chip to warp. The
warping is registered as a change of resistance in the
strain gauges of a Wheatstone bridge. The change in
resistance is converted into an analogue output signal.
The DPI+T also transforms the temperature of the
medium into an electrical signal.
This Product guide describes Grundfos pressure
transmitters.

.
Grundfos pressure transmitters
The three pressure measuring methods are absolute,
relative and differential pressure.
• Absolute pressure is zero referenced against a
perfect vacuum.
• Relative pressure is zero referenced against
ambient air pressure.
• Differential pressure is the difference between two
pressures
The Grundfos pressure transmitter range contains both
relative and differential pressure transmitters. The
combination of the temperature transmitter with either
the relative or differential pressure transmitter are able
to measure temperatures in the range of -22 to 248 °F
[-30 to 120 °C].
Relative Pressure Transmitter (RPI)
The central part of the relative pressure transmitter is a
sensor chip, which transforms the pressure into
electrical signals. The pressure differences between
the ambient pressure and the measured pressure will
cause the sensor chip to warp. The warping is
registered as a change of resistance in the strain
gauges of a Wheatstone bridge. The change in
resistance is converted into an analogue output signal.
The RPI+T will also transform the temperature of the
medium into electrical signals.
The signals are calibrated, conditioned and presented
in analogue or digital format by means of a
microprocessor. The pressure signals are temperature
compensated and linearized for the influence of
temperature variations.

by pressure on both sides.
Sensor chip
Steady state properties of silicon protects the sensor
chip against wear and tear. Lifelong nano-coating
protection enables for the first time, direct
measurement (wet and wet-wet) in a cost effective
packaging for aggressive media. The secret is a metalglass alloy coating, Silicoat® with an extreme
resistance to corrosion. Compared to traditional sensor
technologies which encapsulate the unprotected
measuring cell from the Media, Silicoat® ensures a
continuous protection of the Sensor Chip in aggressive
media (ph 2-ph 11) at temperatures up to 248 °F
[120 °C].
The trademark for Grundfos Direct Sensorsറ is owned
and controlled by the Grundfos group.
Differential Pressure transmitter (DPI and
DPS)
The central part of the differential pressure transmitter
is a sensor chip, which transforms the differential
pressure into electrical signals. The difference
between the two pressures, called the differential

Technical overview
Approvals
Grundfos Direct Sensorsറ, type DPI, are an industrial
differential pressure transmitter, designed to be
mounted directly in the pipe system (V.2). The DPI +T
version can also measure temperature in the range 32
to 212 °F [0 to 100 °C]. The DPI have a standard M12
connector.

Sensor chip
Steady state properties of silicon protects the sensor
chip against wear and tear. Lifelong nano-coating
protection enables for the first time, direct
measurement (wet and wet-wet) in a cost effective
packaging for aggressive media. The secret is a metalglass alloy coating, Silicoat® with an extreme
resistance to corrosion. Compared to traditional sensor
technologies which encapsulate the unprotected
measuring cell from the Media, Silicoat® ensures a
continuous protection of the Sensor Chip in aggressive
media (ph 2-ph 11) at temperatures up to 248 °F
[120 °C].

TM04 4738 0509
Differential pressure transmitter, Industrial
Fig. 75 DPI transmitter
Technical overview
Grundfos Direct Sensorsറ, type DPI, are a series of
differential pressure transmitters for industry. The DPI
sensors are compatible with wet, aggressive media
and are available for differential pressure ranges from
0-9 psi to 0-145 psi.
Sensor chip
Steady state properties of silicon protects the sensor
chip against wear and tear. Lifelong nano-coating
protection enables for the first time, direct
measurement (wet and wet-wet) in a cost effective
packaging for aggressive media. The secret is a metalglass alloy coating, Silicoat® with an extreme
resistance to corrosion. Compared to traditional sensor
technologies which encapsulate the unprotected
measuring cell from the Media, Silicoat® ensures a
continuous protection of the Sensor Chip in aggressive
media (ph 2-ph 11) at temperatures up to 248 °F
[120 °C].

Features
TM03 8138 0607
Relative pressure sensor, standard
Fig. 101RPS sensor
Technical overview
Grundfos Direct Sensors™, type RPS, is a series of
combined pressure and temperature sensors (two-inone) designed for high-volume production. The RPS
sensors are fully compatible with wet, aggressive
media and are available for pressure ranges from 08.7 to 0-145 psi (relative pressure).
• Pressure ranges: 8.7 to 145 psi.
• voltage output (ratio metric, ideal for use with micro
controller)
• compact and robust mechanical design
• approved for potable water: WRAS, KTW, W270,
ACS.
• Max cable length (standard): 10 ft [3 meters]*
• Approved for EU, US and Canadian markets.
Benefits
• Pressure and temperature sensor in one package
(two-in-one sensor)
• compatible with wet, aggressive media
• accurate, linearised and temperature-compensated
pressure sensor
• quick temperature response (direct media contact).
Sensor chip
Steady state properties of silicon protects the sensor
chip against wear and tear. Lifelong nano-coating
protection enables for the first time, direct
measurement (wet and wet-wet) in a cost effective
packaging for aggressive media. The secret is a metalglass alloy coating, Silicoat® with an extreme
resistance to corrosion. Compared to traditional sensor
technologies which encapsulate the unprotected
measuring cell from the Media, Silicoat® ensures a
continuous protection of the Sensor Chip in aggressive
media (ph 2-ph 11) at temperatures up to 248 °F
[120 °C].
Applications
• Domestic hot-water system efficiency
• water level in central heating system
• dry-running protection in solar systems and gas
boilers
• monitoring of pressure and temperature.
• solar system
• heat pumps

Technical overview
Grundfos Direct Sensorsറ, type DPS, is a series of
combined differential-pressure and temperature
sensors (two-in-one). The DPS sensors are fully
compatible with wet, aggressive media.
Sensor chip
Steady state properties of silicon protects the sensor
chip against wear and tear. Lifelong nano-coating
protection enables for the first time, direct
measurement (wet and wet-wet) in a cost effective
packaging for aggressive media. The secret is a metalglass alloy coating, Silicoat® with an extreme
resistance to corrosion. Compared to traditional sensor
technologies which encapsulate the unprotected
measuring cell from the Media, Silicoat® ensures a
continuous protection of the Sensor Chip in aggressive
media (ph 2-ph 11) at temperatures up to 248 °F
[120 °C].
