NORGREN 0881300 Pressure Switch 0.5 to 8bar Electromechanical Pressure Monitor for Air Supply System

Product Description:

The NORGREN 18D Series (Model 0880 / 0881) electro-mechanical pneumatic pressure switch is a well-established diaphragm-actuated pressure monitor designed for industrial automation applications. It serves effectively in pressure alarms, interlock systems, and loop control processes. Manufactured by IMI Norgre, this series accommodates a wide pressure range from vacuum conditions up to 30 bar of working pressure.

Multiple port options are provided to suit various installation requirements, including G1/4, 1/4 NPT, and flange mounting configurations. Users can select between two types of electrical connections: the DIN EN 175301-803 Form-A and the M12×1 IEC 947-5-2 connectors. Additionally, LABS-free variants and brass-body special versions optimized for water service are available, making this switch suitable for neutral gases, liquids, and water media environments.

The pressure switch is equipped with a gold-plated contact microswitch, which holds certifications from UL and CSA. It ensures intrinsically safe operation and withstands vibration resistance up to 15 g. The mechanical service life of the device can reach up to 10 ⁷ switching cycles, offering excellent repeatability and reliable long-term performance.

The standard housing is made from aluminium alloy, while models designed for water applications use brass housing for enhanced corrosion resistance. Seal options include NBR and FPM materials. The maximum ingress protection rating is IP67, making it suitable for demanding and harsh factory environments.

When the system pressure reaches the designated set-point, the SPDT micro-switch outputs an electrical signal to activate machine interlocks, alarms, or on-off control systems in pneumatic machinery, hydraulic circuits, and water treatment equipment.

Note: For optimal performance, set-points should be positioned near the middle of the pressure range. It is crucial not to exceed the rated pressure indicated on the nameplate. Inductive loads require spark-quenching protection circuits. Connectors must be purchased separately as DIN or M12 plugs are not included with the product.

Applications:

Pressure monitoring and alarm systems play a crucial role in industrial pneumatic automation. These systems ensure reliable operation by constantly tracking pressure levels and providing timely alerts when pressure deviates from the set parameters.

In addition, compressor and vacuum pump operations are safeguarded through pressure interlock protection. This feature helps prevent equipment damage by ensuring that the machinery operates only under safe pressure conditions.

Hydraulic fluid power systems benefit from precise pressure signal feedback, which allows for accurate control and optimization of hydraulic processes. This feedback mechanism is essential for maintaining system performance and preventing faults.

Water‑treatment and water‑supply equipment often utilize specially designed brass water‑service variants. These components are tailored to withstand the demands of water applications while ensuring durability and reliable pressure monitoring.

Pressure detection is also vital in packaging machinery, machine tools, and conveyor equipment. Continuous pressure monitoring helps maintain operational efficiency and safety across these various mechanical systems.

Moreover, over-pressure alarms coupled with machine start-stop control improve the safety of industrial fluid pipelines. These controls help to prevent pipeline failures and ensure safe operation by reacting promptly to excessive pressure situations.

Lastly, general‑purpose machinery benefits from vacuum monitoring and control to maintain optimal operating conditions. Effective vacuum management supports the performance and longevity of diverse industrial equipment.
