Corrosion-resistant gauge protectors

ASV Stubbe has redesigned its range of corrosion-resistant gauge protectors. With the body and bonnet now being connected by a special thread, the need for metal fixings has been eliminated.

Type MDM 902 gauge protectors feature a liquid-filled cavity together with a durable and flexible diaphragm to transmit process pressure to an instrument, thus offering an economical method of protecting instruments such as pressure gauges, pressure switches, etc from corrosion and clogging, while maintaining a high degree of accuracy.

Body materials of PVC, PP and PVDF, together with a PTFE-coated diaphragm, make the units suitable for use in systems controlling a variety of media ranging from water to the harshest chemical. The PTFE-coated diaphragm safely protects the pressure measuring device from corrosive attack.

End connections, threaded G¼ and G½", with NPT threads available if required, also double as spigots (sizes d25 or d32), which are suitable for solvent welding (PVC) or fusion welding (PP and PVDF). The units perform with a high degree of accuracy, low pressure differential and low hysteresis in applications up to 10 bar.
