Devices from the 111.12 series offer similar parameters to those from the 111.10 series described above, however, they are equipped with rear connections with G 1/8 B, M10, M12 or M20 threads. A membrane separatorhas been used here as well, making it possible to work with viscous substances. Gauges are available in diameters from 40mm to 100mm. They can be used in a wide range of industrial applications, with liquid and gaseous media. They meet the requirements of the EN 837-1 construction standardand the accuracy requirements under EN 10204(1.6 or 2.5).
