Magnetic coupling piston type differential pressure gauges (ce certified model)these gauges are suitable for non-magnetic fluids only. Model : 200 dpg range : various ranges from 0.25 to 10 bar dial size : various options like 2, 2 12, 3 12, 4, 4 12, 6 dia. Connection : 14 npt - f (optional bsp) accuracy : + - 2% fsd (ascending) working pressure : high static pressure - 100 kgcm2 porting : options like - inline, back or, bottom calibration : non-linear, spread over 65 degrees to 75 degrees arc. Sensing element : piston wetted parts : aluminium, brass, ss 316, buna n, viton max. Working temp.: max. 80 degree c if buna n is used, it can be max. 200 degree c if viton is used. Enclosure : ip 65 singe or, duel reed switch contacts can be provided along with dp gauge, either in ip 65 or, in flameproof enclosure
