Electrical Contact Switches For Pressure Gauges

Electrical Contact Switches for pressure gauges

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 percent 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 percent 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 percent of final scale value

Options

• Longer Cable
• Spare Adjustment Keys

As switch contacts, magnetic snap-action contacts, reed switches, inductive contacts and electronic contacts are available. Inductive contacts can be used in hazardous areas. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used.
