Beck 930 Adjustable Differential Air Pressure Switch
The Beck 930 series is an adjustable differential pressure switch designed to monitor over-pressure, vacuum, or differential pressure in air and other non-combustible, non-aggressive gases. It is widely used in HVAC, ventilation, and industrial air systems for reliable pressure control and monitoring. The switch point can be easily adjusted using a built-in knob without the need for external tools or gauges.

Frequently Asked Questions
Q1. What is the Beck 930 differential air pressure switch used for?
The Beck 930 differential pressure switch is primarily used to monitor and control air pressure in HVAC systems, ventilation ducts, industrial cooling circuits, and filter monitoring applications. It helps detect over-pressure, vacuum, or differential pressure in air and other non-aggressive gases.
Q2. How do you adjust the set point on the Beck 930 differential air pressure switch?
The set point on the Beck 930 can be easily adjusted using the built-in adjustment knob located inside the housing. No external tools or pressure gauges are required, making on-site calibration quick and convenient.
Q3. What pressure ranges are available in the Beck 930 series?
The Beck 930 series is available in multiple adjustable pressure ranges, including 20–200 Pa, 20–300 Pa, 30–400 Pa, 50–500 Pa, 100–1000 Pa, 500–2500 Pa, 1000–4000 Pa, and 1000–5000 Pa. This wide range allows users to select the most suitable model for their specific system requirements.
Q4. Can the Beck 930 pressure switch be used in humid or dusty environments?
Yes, the Beck 930 is available with an optional IP65 protection rating, which makes it suitable for dusty or moderately humid environments. For standard indoor applications, the IP54 version is typically sufficient.
Q5. What is the recommended installation position for the Beck 930 differential air pressure switch?
For the most accurate switching performance, the Beck 930 should be installed vertically with the pressure ports facing downward. Horizontal installation is possible but may introduce a small pressure offset of approximately +20 Pa.
