Gauges

We supply a complete range of differential pressure and float level gauges for all size and types of cryogenic vessels & trailers.

From the standard through to the next generation, there will be a gauge for your application, that not only beats competitors on quality, but also on delivery, price, performance and service.

Combined DP & Pressure Gauge

The combined DP and pressure gauge options have a ±2% full scale accuracy. This type of diaphragm model is used in applications where no migration of the media from high pressure side (HP) to low pressure side (LP) is permitted.  Options include oxygen cleaned and switch options, 1 & 2, for remote outputs.

  • Accuracy: ±2% of the FSD (Ascending)
  • Migration: Zero Migration from high to low port
  • Range: 0-0.075 to 0-7 bar (0-1 to 0-100 psi)
  • First marking on scale: 15% of the FSD
  • Mounting: Direct, front flange, 2” pipe & surface mounting
  • Case material & dial size: Stainless steel (SS 304): 150mm
  • Wetted Parts: Diaphragm, body material, SS 302 spring & ceramic magnet
  • Maximum Working Pressure: 75 bar / 1000 psi
  • Design Temperature: -40°C to 80°C / -40°F to 175°F
  • Body Material: Aluminium, Brass, SS 316
  • Window: Float, Toughened glass, acrylic & safety glass
  • Connection: Standard: ¼” BSP (F) Optional: ¼” NPT (F) with adaptor
  • Porting: In-line, rear, bottom, bottom & vent, in-line & vent, in-line & bottom, Barton replacement adapters
  • Protection: IP 65 / NEMA-4
  • Diaphragm: Buna-N, Viton, Silicon
  • Scale: Standard Pressure unit, Volumetric & weight (need detailed internal tank drawing)
