Adjustment in the range: from -0.4 to -3 mbar.
Response interval: 0-0.3 mbar.
Environment: gas of 1-3 families, flue, exhaust, neutral gases, air.
Permissible operating temperature: -15°C to +70°C.
Connection: thread G1/4 and G1/8 inches.
Design and features
The device is equipped with a reliable moisture- and dust-proof metal case of class IP 65. The base is aluminum, the cover is zinc casting. The sensitive membrane is made of NBC.
Gold-plated contacts are used to increase electrical conductivity and ensure uninterrupted switching.
The device switch responds to the differential pressure between the chambers, closing, opening or switching the contacts of the electrical circuit when the pressure increases or decreases relative to a fixed value.
The response parameters are adjusted manually by turning the wheel. A digital scale is provided for ease of adjustment.
The relay is screwed directly onto a pipe with an external thread R 1/4. The standard installation position is vertical. With a different mounting orientation, the response point will shift (see the instructions for the device).

stable switching;
highly sensitive membrane;
simple adjustment;
reliable operation in adverse conditions;
metal impermeable housing;
threaded connection.
