Beschrijving

This differential pressure switch or pressure switch can easily be set to switch at the desired pressure difference. In this way you can check filters for saturation, or rooms for over- or underpressure, etc.
The switching capacity is 1 A at 250 VAC and the pressure range is between 20 and 200 Pa. The set also includes the PVC connection set with transparent hose of 2 meters and the plastic connection pieces.

How does a differential pressure switch work?
A differential pressure switch functions by detecting pressure variations between two designated points . It consists of two ports that are connected to their respective pressure sources, allowing the pressure difference between them to be monitored. When this difference exceeds a predetermined threshold, the internal diaphragm of the switch deflects, either establishing or breaking a circuit connection. This change in the circuit activates an alarm, notifying users of the pressure change. Users have the ability to preset the switching threshold or adjust it on-site.The product series
The PSW series differential pressure switches serve various purposes, such as switching fans or pumps on or off and monitoring the status of air filters in ventilation systems and air handling units . They are used in air handling units with heat exchangers to protect against freezing or to protect electric duct heaters from overheating. These switches are designed to monitor overpressure, vacuum and differential pressure of air or other non-flammable, non-aggressive gases.
The PSW--200-PVC includes the PSW switch itself, PSET-PVC connection nozzles and 2-meter plastic tubes with mounting screws.
The PSET-PVC connects the differential pressure switch to the ductwork and allows the differential pressure to be measured in Pascals. The nozzles are made of high-quality, heat-resistant gray r-ABS plastic, with a length of 83 mm and a diameter of 6.4 mm at the connection end. The tubes are made of transparent PVC, with a diameter of 7 mm and a length of 2 m, with a maximum working pressure of 10,000 Pa and a maximum operating temperature of 60 °C.
The dry contact output of the differential pressure switch has an average life of 10,000,000 operations, with contact ratings of 1 A for resistive loads or 0.4 A for inductive loads (at 250 VAC).Simplified installation
Installation is simple : simply mount the device on a suitable surface. Please note that the differential pressure switch must not be installed upside down at a cut-out pressure of less than 50 Pa!
Connector P1 is intended for the higher pressure or lower vacuum, while connector P2 is for the lower pressure or higher vacuum. When the pressure difference increases, contact 3-2 closes and contact 3-1 opens.Protective housing
The switch is housed in a sturdy housing with a plastic cover, which provides protection against the ingress of dust, dirt and water. In combination with the plastic cover, the protection class is IP54 .
