Air Differential Pressure Switch – Adjustab...
Rs.2,400.00Product details
Product Description
The Air Differential Pressure Switch is an adjustable pressure switch used to monitor the difference in air pressure between two points and switch an electrical contact when a set pressure is reached. Choose the range that suits your application — from 20 Pa up to 5000 Pa — and set the exact switching point using the scaled dial under the clear cover.
It is designed for HVAC and ventilation systems, where it is commonly used for airflow proving across fans, dirty-filter detection on air handling units, and monitoring duct or room pressure. The unit connects to the airflow through the included duct air-pickup probe and flexible sensing tubes, so it can be fitted to a duct or plenum during installation.
The switch uses a diaphragm-operated mechanism and a built-in changeover contact, so it does not need its own power supply to operate — it simply opens or closes your control or alarm circuit at the set pressure. The housing is surface mountable using its integral fixing tabs, with a cable gland for tidy wiring entry.
Select your required pressure range from the options above. Contact rating, ingress protection and exact dimensions are not marked on this unit; if your application needs specific electrical or IP figures, contact us before ordering and we will confirm suitability.
