Onyx Pressure Sensors provide a simple, method to measure pressure of slurries and corrosive fluids. They provide accurate alignment and minimum weight at the lowest installed cost.

PSW

The PSW series is compatible with flanged pipe connections. Nesting inside the bolt circle of mating flanges provides accurate alignment and minimum weight at the lowest installed cost.

The inside diameter of the PSW precisely matches standard pipe for smooth, unobstructed flow, self-cleaning operation, and minimum turbulence and friction. Onyx ultra-deep vacuum filling insures the highest accuracy in the industry. The patented “Module Seal” – standard on all Onyx Isolator Rings – allows instruments to be or replaced or calibrated with minimum down time.

  • Absolute immunity to clogging
  • Combines accurate alignment, reduced weight, andmaximum economy
  • Mates with 150# flanges, compatible with 300# or 600#flanges with adapters
  • Superior accuracy compared to diaphragm seals
  • No tools required to change pressure instrument
  • High displacement design can operate up to three instruments on one ring

PSR

The PSR series is compatible with flanged pipe connections. The full face thru bolt holes match the bolt circle of mating flanges for accurate alignment making it the ideal choice for use with non-metallic flanges.

The inside diameter of the PSR precisely matches standard pipe for smooth, unobstructed flow,self-cleaning operation, and minimum turbulence and friction. Onyx ultra-deep vacuum filling insures the highest accuracy in the industry. The patented “Module Seal” – standard on all Onyx Isolator Rings – allows instruments to be or replaced or calibrated without interrupting the process.

  • Absolute immunity to clogging
  • Available with either 150# or 300#
  • Integral snubber eliminates gauge fluctuations at no additional cost
  • Instruments can be replaced without vacuum filling
  • Immune to errors caused by ambient temperature fluctuations
  • No tools required to change pressure instruments

PSS

The PSS series is compatible with threaded pipe connections. Onyx ultra-deep vacuum filling insures the highest accuracy in the industry. The patented “Module Seal” – standard on all Onyx Isolator Rings – allows instruments to be or replaced or calibrated without interrupting the process.

  • Low-Cost
  • Superior accuracy compared to diaphragm seals
  • Instruments can be replaced without removing the isolator
  • ring from the pipe
  • Immune to errors caused by ambient temperature fluctuations
  • Integral snubber eliminates gauge fluctuations at no
  • additional cost
  • Silicone oil fill fluid is safe, non-toxic, non-corrosive, and stable from -40°F to +400°F

PSQ

The PSQ series is compatible with Tri-Clover pipe connections. Quick connection to Tri-Clover pipe provides accurate alignment and fast installation.

The inside diameter of the PSQ precisely matches sanitary pipe for smooth, unobstructed flow, self-cleaning operation, and minimum turbulence and friction. Onyx ultra-deep vacuum filling insures the highest accuracy in the industry. The patented “Module Seal” – standard on all Onyx Isolator Rings – allows instruments to be or replaced or calibrated without interrupting the process.

  • Absolute immunity to clogging
  • Tri-Clover fittings allows for quick disconnect from piping system
  • FDA Silicone oil fill fluid is safe, non-toxic, non-corrosive, and stable from -40°F to +400°F
  • High displacement design can operate multiple instruments on one ring
  • Ideal for brine, pickling solutions, tomato paste, chilies, mustard, pet food, and chocolate
  • No tools required to change pressure instrument

Smart Box-4

Smart Box-4 insures safe, reliable operation of progressing cavity pumps, protecting them from over-pressure, run-dry situations, or seal water failure. This latest generation Smart Box is versatile, easy to install, easy to use, and compatible with either fixed speed or variable speed pumps.

The Smart Box-4 uses a solid state PLC and touch-screen for maximum reliability, eliminating wiring, mechanical push buttons, and lights. The touch-screen interface displays simple animated graphics so pump status and fault conditions are easy to understand. It comes standard in a fiberglass weatherproof (NEMA-4X) enclosure, with optional stainless steel also available. It operates on 120-230 VAC power and includes its own internal DC power supply.

Working in combination with the Onyx Isolator Ring ensures reliable operation with abrasive slurries, viscous fluids, suspended solids, and corrosive liquids.

Diaphragm Seal Model K

The Onyx Model-K series diaphragm seal provides outstanding protection for pressure instruments against chemical attack and corrosion.

  • Compact design takes up little space and light weight
  • High available displacement volume can drive multiple instruments with a single diaphragm seal, including instruments with large bourdon tubes or diaphragms.
  • High system accuracy is assured by the combination of large surface area and ultra-low modulus of elasticity of the diaphragm element.
  • Teflon-coated Viton diaphragm offers outstanding chemical compatibility with a wide variety of process fluids. Wetted materials of construction include 316-stainless steel, PVC, and Kynar for broad based chemical resistance.
  • Optional Clamp-Ring design enables users to remove the pressure instruments with the top half of the diaphragm assembly without fill fluid loss or compromising the vacuum seal.
  • Optional flush port is available for cleaning in place.
