Product Introduction

The switch contacts (electrical switch contacts) connect or disconnect the electrical control circuit according to the  pointer position of the indicating measuring instrument. The switch contacts can be adjusted throughout the entire  range of the scale (see DIN 16085), mainly installed below the dial, but also partially above the dial. The instrument  pointer (actual value pointer) moves freely throughout the entire scale range, regardless of the setting.

The set pointer can be adjusted using a removable adjustment key in the window.A switch contact consisting of two  contacts can also be set as a single set point. When the actual value pointer moves beyond or below the desired set  point, contact actuation will be performed.

Special Features

• Up to 2 switch contacts per instrument.

• Instruments with inductive contacts for use in hazardous areas.

• Instruments with contacts for PLC applications.

• Safe type with solid barrier wall (Solidfront).

Applications

• Control and regulation of processes.

• Monitoring of plants and switching of circuits.

• For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive      environments.

• Chemical, petrochemical, power plant, mining, onshore/offshore, environmental technology, machinery manufacturing,      and general factory construction.

Key Selection Points

• Range: Commonly 0…16 bar, 0…25 bar, 0…40 bar.

• Connection: G¼B (Metric) or ¼ NPT (Imperial).

• Contacts: Quantity (1/2), Type (Magnetic-assisted / Inductive), Function (Normally Open / Normally Closed).

• Safety: Choose S3 for high-risk working conditions to prevent bursting.

• Installation: Radial (bottom connection) or axial (rear connection).
