DESCRIPTION: pressure switches are two-stage devices that switch a contact when certain air or fluid pressures are reached. The HEATING series one-stage adjustable differential pressure switch by Milano Componenti stands out for its high reliability. The cut-in pressures can be pre-set or adjustable.
APPLICATIONS: particularly suitable for high pressures, adjustable pressure switches are generally used in control systems, and in particular in the boiler, compressor, coffee machine and boiler sector, to control the level of pressure in the appliance. The pressure switch for compressors by Milano Componenti can also perform anti-overflow and resistance protection functions.
OPERATION: the moving part of the heating series one-stage adjustable differential pressure switches, formed by a membrane and a disc, operates a snap-action changeover contact, which can be duly set to the required pressure level.
MATERIALS: body in self-extinguishing glass-fibre reinforced polyamide PA 66, flame retardant up to 850°C (Glow Wire test); silver-plated brass terminals; CuBe (beryllium copper alloy) movable contact strip; silver-alloy contact. The membrane can be made of steel, EPDM or silicone.
VERSIONS: electromechanical pressure switches are available in the version with either a centre or a side spout (pressure inlet). In the latter case, the specific clip for quick coupling on the mounting template can be requested.
On request and for sufficient quantities, Milano Componenti also develops special versions of pressure switches for compressors to the client’s design.
