Pressure Monitor suits Class 1, Div 2 hazardous locations.

Pressure monitoring solution utilizes Onyx Isolator Ring and multi-function SGTÂ-® pressure instrument. Vacuum-filled with silicone-fluid, isolator ring obtains pressure measurements on slurries, abrasives, and hard-to-handle materials. SGT electronic pressure instrument provides 2 relays, local indication, and 4-20 mA output. Unit is equipped with self-diagnostics, on-line testing, and...

Fluid & Gas Flow Equipment

Pinch Valve controls abrasive, viscous, and corrosive fluids.

CAR pneumatically actuated pinch valve employs spring for fail-safe operation. It consists of rubber compression-molded sleeve inside full round cast iron bonnet. Available in Fail Open (PFO) or Fail Closed (PFC) construction, valve features smooth operation. Closure is drop-tight, and no lubricated air is necessary. Applications include control of wastewater, chemicals, mine slurries, cement,...

Isolator Ring obtains accurate pressure measurements.
Electrical Equipment & Systems

Isolator Ring obtains accurate pressure measurements.

For measuring pressure of slurries, abrasives and hard-to-handle materials, isolator ring supports up to three gauges, pressure switches and transmitters. It is vacuum-filled with high-viscosity silicone fluid and permanently sealed. Gauges can be removed, replaced, or hand-rotated without interrupting process. No tools are required to change pressure instruments, which can be removed and...
