For those users needing a pressure gauge with switching capability and stainless steel construction, KOBOLD provides the model DRG26. Stainless steel movement, wetted parts and housing provide elevated resistance to corrosive chemicals. A rear blow-out membrane in the housing provides users with an added level of protection from catastrophic failure caused by overpressure. Mounting options are: stem supported or panel mount with rear fittings. The DRG26 is fitted with up to two magnetically coupled or inductive switches. Paraffin oil filling is available to damp movement caused by pressure surges and pulsations. Either four inch or six inch housings and dials are available ... letting the user choose whatever level of readability desired.
