The DRF34 pressure gauge provides pressure switching in addition to pressure indicating capability. Its bourdon tube sensing element and indicator movement are made of copper alloy while the housing with a bottom fitting is made of stainless steel. With rear mounted fittings, the housings are made of aluminum and feature a panel-mounting bezel. This gauge offers one or two magnetically coupled or inductive switches. Paraffin oil filling is also available as an option to dampen movement caused by pressure surges and pulsation.
