Beck. The adjustable Differential pressure switches Climair® with UL approval

Product catalog summary

Overview: The Beck Climair® 930.8x series are adjustable differential pressure switches with UL approval, designed for monitoring overpressure, vacuum, and differential pressure in air or non-combustible, non-aggressive gases.

Applications: These switches are suitable for monitoring air filters, ventilators, industrial cooling-air circuits, fan heater overheating protection, ventilation duct flows, air and fire-protection flaps, and frost protection for heat exchangers.

Specifications:

Pressure Connections: Two plastic pipe connections (P1 and P2) with an external diameter of 6.0 mm.
Housing Material: Plastic switch body and cover.
Weight: 150 g.
Life Cycle: Mechanically over 1 million cycles.
Electrical Rating: Standard version supports up to 1.0 A / 250 VAC; low-voltage version supports up to 0.1 A / 24 VDC.
Protection: IP54 rated.
Conformity: CE, ANSI, UL508, CSA C22.2#14.

Versions and Adjustments: The switches offer various adjustment ranges from 20 Pa to 5000 Pa, with repeatability and deviation specifications. The switching pressure can be adjusted without a gauge using a scaled knob.

Environmental Conditions:

Temperature Range: Medium and ambient temperatures from -20°C to +60°C; storage temperature from -40°C to +85°C.
Diaphragm Material: Silicone, free of gas emissions.

Accessories: Includes various mounting brackets and Climaset® options, which consist of hoses and tubes for different configurations.

Order Matrix: Provides detailed options for pressure ranges, switching contacts, fitting methods, adjustment scales, IP protection categories, packaging, and accessories.
