The AFRISO NS 50 (NS 63) Bourdon tube pressure gauge for chemical applications is used to measure the pressure of gaseous and liquid media at temperatures of up to 150  C (NS 63 up to 200 °C)in the measuring ranges 0/0.6 bar to 0/600 bar (0/0.6 bar to 0/1000 bar).

The robust design with a measuring system that is completely welded to the housing makes for a shock- and vibration-resistant unit that does not require seals. This keeps the risk of leaks to a minimum and ensures high long-term stability. The device is available with G¼B – size 14 (EN 837-1/7.3) process concretions: bottom, centre back, bottom back and other connections on request. The pressure gauges for chemical applications NS 50 and NS 63 are tightness-tested with Helium and feature a stainless steel housing with blow-out; NS 50 has a plastic window, NS 63 a laminated safety glass window. The pressure gauges are optionally available with clamp fixing, a 3-hole front flange, special scales and an ATEX version. The Bourdon tube pressure gauges for chemical applications NS 50 and NS 63 are DNV- and GOSSTANDART-certified and suitable for chemical and process engineering applications.
