The JCE EFS-02 Pressure Flow Switch is designed to monitor differential pressure or airflow in HVAC systems and industrial ventilation. It is suitable for detecting blocked filters, fan operation, flue draft, and air movement, and works with positive, negative, or vacuum pressure in non-corrosive, non-combustible gases.
This compact switch is housed in a zinc-plated steel enclosure and supports volt-free SPDT switching at 230 VAC. It operates within a pressure range of 0.13 to 30 mbar and features an adjustable switching differential between 0.05 and 2 mbar. A high temperature version (EFS-02HT) is also available, rated for up to 300°C.
The switch includes 6 mm compression connections and is IP30 rated. For high temperature applications, brass duct adaptors are provided, and installation should include at least one metre of pressure line to ensure accuracy. The unit can be mounted in various orientations depending on the application requirements.
