PRESSURE SENSOR
EXPERTISE
In the field of pressure sensor technology, Norgren employs different techniques which enables us to offer the most appropriate solution to our customers. Our product portfolio extends from robust electro-mechanical pressure switches to intelligent and teachable electronic switches and sensors.
Electro mechanical pressure switches
Mechanical pressure switches are used to connect and disconnect electronic circuits depending on the operating pressure. Norgren’s pressure switches deliver safe and reliable minimum pressure monitoring and offer the advantages of automatic switch off and pressure limit warnings.
The life span and accuracy of mechanical pressure switches depends on the frequency and peaks of pressure changes, number of load cycles and the influence of temperature.
Electronic pressure switches and sensors
Electronic pressure switches and sensors are particularly suitable in applications where the classic mechanical pressure switch is not suitable. Offering benefits in accuracy, life span and functionality Norgren’s range is highly suitable for modern manufacturing technologies.
Pressure set points are adjustable by using integrated LED’s, LED or LCD digital display. This offers today’s modern automation process the advantages of easy set up and time savings.

01THE NEW 33L PRESSURE SWITCH OFFERS HIGH FUNCTIONALITY AND VERSATILITY
SENSING OF COMPONENT POSITION IN POLISHING PROCESS
PRESSURE SENSOR
APPLICATIONS
Nagel GmbH manufactures super finishing and tape finishing machines for automotive components. The company has purchased pneumatic air gap monitoring systems that will be incorporated in polishing machines.
The air gap monitoring system senses whether the component is correctly positioned prior to polishing. Between operations the unit also blows the area clean. These products operate at 16 bar with one outlet.
The 33D electronic pressure switch is the control element of the air gap monitoring system and provides high accuracy.
CONTROL OF VARIOUS FLUIDS IN PAINTING PLANTS
Duerr Systems GmbH manufactures painting production lines for automotive plants. Pressure switches are located at various positions in this system controlling the pressure of fluids including compressed air and water.
The electro-mechanical 18D provides a labs-free and cost-effective solution to our customer production lines.
PRESSURE CONTROL ON PRINTING MACHINES
MAN Roland Druckmaschinen AG uses the Norgren 33D to monitor the folding operation. Switching points at 6.05 bar (timed) and 5.05 bar ensure the
pressure is sufficient. The 33D offers two switching points and has replaced the two pressure switches from a competitor previously used to perform this operation. The 33D is a much more cost-effective solution for MAN Roland.
Other Applications:
pressure monitoring in the main air line (8 bar) pressure control at the printing unit
pressure control in the automatic roll changeover
MACHINE TOOLS
SENSING LABEL IN VACUUM RANGE
In production labels are applied automatically to the valves. The 40D pressure switch is used by leading manufacturers of labelling equipment to sense the change in vacuum pressure when there is a label present on the pad. This pressure switch has a range sensitive enough to carry out the required task.

Keypad with 3 user-friendly buttons
The keypad with 3 user-friendly buttons allows
comfortable and easy programmingof set / reset points as well as other 33L functions
Electronic lock (including master-key function) to prevent unauthorised personnel from changing the set-up, resulting in higher plant security
Configurable without operating pressure to save timeat the programming stage
Self-diagnosis function to detect errors resulting in
higher plant security 2
High functionality and versatility
The 33L optionally offers threaded (G, NPT) or flanged process connections according to customer demands Available as pneumatic, vacuum, hydraulic and allfluid versions up to 600 bar to suit many applications
3
Output signals
The 33L has two digital outputs. The standard version provides a switching output and a warning output, which can also be programmed as an additional switching output. This provides higher functionalityfor Norgren customers
