Electrical Contacts

Electrical Contact Switches for pressure gauges switch depending on the direction of movement.  This will open or close electrical circuits at the set limit values by means of a contact arm which is moved by the gauge pointer.  These can be single or double contact, supplied with a metre of cable and an adjustment key to be set by an end user.

Low Action Contacts

Are used in the absence of high contact loads and vibrations.

• Nominal operating voltage: max. 250 V
• Making and breaking current: max. 0,7 A
• Breaking capacity: 10 W 18 VA
• Switching precision: approx. 0,5 % of final scale value

Snap Action Contacts

Can be used under almost all operating conditions and are partially not affected by vibrations.

• Nominal operating voltage: max. 250 V
• Making and breaking current: max. 1,0 A
• Breaking capacity: 30 W 50 VA
• Switching precision: approx. 2-5 % of final scale value

Inductive Contacts

Are equipped with non touching proximity NAMUR switches. They should be preferable used with oil filled measuring instruments. With an ex-prooved isolating amplifier they can be used in explosion proof areas.

• Rated voltage: 8 V DC
• Switching precision: approx. 0,5 % of final scale value

Options

• Longer Cable
• Spare Adjustment Keys
