Description
An RT pressure switch contains a pressure operated single-pole changeover contact, the position of which depends on the pressure in the inlet connection and the set scale value. The RT series includes pressure switches for general applications within industrial and marine refrigeration.
The RT series also includes differential pressure switches, pressure switches for neutral zone regulation, and special pressure switches with gold-plated contact surfaces for PLC applications.
Features
- Versions with enclosure IP66
- Wide regulating range
- Wide range of units for industrial and marine applications
- Suitable for alternating and direct current (AC and DC)
- Interchangeable contact system
- Special versions for PLC applications
- Safety Integrity Level : SIL 2 according to IEC 61508
