Draught gauges DT-SV

The instruments are designed to measure vacuum and gauge pressure of air, natural and other gases that are not aggressive to the contacting materials (tin-lead solder PIC 61 GOST 21930-
76, bronze BrB2 GOST 18175-78, copper grades M1, M2, M3 GOST 859-2001, brass LS59-1 GOST 15527-2004), and for switching of external electrical circuits in systems of general industrial, industrial and other equipment.
circuits in general industrial, including boiler, automation systems
when the set value of the controlled pressure is reached.
