1 Design Type WIKA type no Case diameter Pressure gauge in stainless steel version with electrial alarm contact. Suitable for aggressive media and environment. DIN contact = stainless steel 2950 contact = stainless steel, liquid filled case PGS23.1x0 Dim 100 or 160 mm Accuracy Class 1,0% Case Window Pressure element Movement Dial Pressure unit Pressure connection Stainless steel with bayonet ring pressure relief on back of case Safety version Laminated safety glass Stainless steel 316L Stainless steel Aluminium, white with black lettering Bar G 1/2 male Weather Protection IP 65 EN 60529/IEC 529 Electrical contacts Electrical functions Electrical connection Contact type 821 Contact type 831 Option designs One or two electrical contact mounted in the case. The contacts can optionally be set all over the scale. Max- and/or minfunction, se table Junction box on right side of the case Voltage max 250 VAC, maximum load 30W, 50 VA The inductive contact is well suited to servere operating conditions, such as extremely swift changes or when an explosion safe design is necessary. The contacts are completely protected from touch and the hysteresis is less than 0,5% Pressure connection G3/8 or 1/2 NPT Design ATEX Ex II 2 GD (contact type 831) Design with SIL2-approval Back connection with front-flange - see page 5 Lower connection with back-flange Pressure range bar 0-1,6 bar 0-2,5 bar 0-4 bar 0-6 bar 0-10 bar 0-16 bar 0-25 bar 0-40 bar 0-60 bar bar bar bar bar bar - -1/0 bar -1/1,5 bar -1/3 bar -1/5 bar -1/9 bar -1/15 bar -1/24 bar

2 Permissible temperature Type 2850 = Medium temperature max -40 till +200 C Type 2950 = Medium temperature max -20 till +100 C Ambient temperature max -40 till +60 C Max permissible error 1,0% The accuracy is expressed as a percentage of full scale range. Permissible error 1,0% will cover 0% till 100% of scale range with a reference temperature of +20 C. Ex. Pressure range 0-10 bar has an error of + 0,1 bar Pressure limitation Full scale value by steady pressure 90% of full scale value by fluctuating pressure By short time pressure 1,3 x of full scale value Temperature effect Temperature of the measuring system over or under the reference temperature +20 C will effect the accuracy with 0,4 percentage per +10 C. With a medium temperature of +40 C the accuracy will be + 1,8%.
