Product Description

Product features:
Differential pressure monitor in the overpressure and negative pressure range. The pressure difference acts on the diaphragm to adjust the spring force on the micro switch. The pressure monitor does not require an auxiliary power supply to operate.
Differential pressure monitor LGW The A4 switching device responds to the pressure difference between two pressure chambers. When the pressure difference is higher or lower than the set rated value, the switching device connects or disconnects a circuit, or causes it to switch. Overvoltage monitor LGW A4 pressure connector G1/4 is a single acting pressure monitor within the overpressure range. The switching device responds to overvoltage, and when it is above or below the set rated value, the switching device connects or disconnects a circuit, or causes it to switch. The pressure joint G 1/8 must not be closed.

Product application: Used for pressure difference monitoring in combustion technology, ventilation technology, and air conditioning technology. Differential pressure monitor: suitable for air, flue gas, and exhaust gas.Overpressure monitor: suitable for gas types 1, 2, 3, and other neutral gaseous media.

Technology:
Differential pressure monitor LGW A4 is an adjustable pressure differential monitor that complies with the EN1854 standard. It is used for combustion equipment to open, close, or switch a circuit based on the relationship between the actual pressure value and the pressure set value. The adjustment of the rated value (reversing point) is carried out on a graduated adjustment wheel. Measurement nozzles are standard in the metal casing
