Differential pressure gauge DR20 series

dialthreadedstainless steel

without liquid filling Service intended: Measurement of pressure differential of 2 pressuresapplied. Suitable for gaseous and liquid, non-crystallizing media that will not obstruct the pressure system. Scale range must be selected in consideration of the highest static pressure applied. When ordering please state both, the static pressure applied and the pressure differential. Fields of application: ● pneumatics, hydraulics ● heating and air conditioning technology ● Filter measurements Construction:similary EN 837-1 Case:Ø 100 and 160 mm stainless steel with pressure relief Protection class:IP 33 per EN 60529 / IEC 529 Pressure connection:2 x G1/2B, parallel behind, stainless steel 361L identified + and - Pressure element:stainless steel 361L Movement:Base and cover plate, brass Dive Shaft, nickel silver Pointer:1 x standard pointer, aluminium, black 1 x rotating pointerscale, aluminium, white red pointer, scale with +/- 50% of indicating range of + and - differential pressure scale Dial:Aluminium white, scale and lettering black Window:Laminated safety glass Accuracy class:class 1,6 Temperature error, Tref 20°C:rising temperature: +0,3 % of FS/ 10 K Falling temperature: -0,3 % of FS/ 10 K Working pressure: Steady : 1,0 x full scale value Fluctuating : 0,90 x full scale value Short time overpressure : 1,3 x full scale value
