BrandRadix
Pressure Range0 to 400 Kg/cm2
UseLiquid
Display TypeAnalog
Pressure TypeGauge Pressure
Model Name/NumberPGS400
Country of OriginMade in India
Radix Sealed Diaphragm gauges are designed for accurate pressure readings in high pressure corrosive environments. A Teflon sheeted SS316L diaphragm protects the pressure gauge from corrosive media and also prevents clogging of the bourdon tube by viscous process media.. The PGS400 gauges are meant for high pressure requirements measuring up to 280 Kg/cm2. These sealed diaphragm pressure gauges are primarily used in applications where the process fluid measured would normally clog the pressure measuring device or where the process fluid in the measuring element might freeze due to changes in ambient temperatures. With an IP68 rating (IS/IEC 60529:2001), PGS400 gauges are completely dust proof and can handle complete continuous submersion in water. With a strong welded steel constructions, the gauges can be directly mounted using their threaded process connection. These gauges are built with a complete stainless steel casing and stainless steel internals. They can also be glycerin filled or with an extension capillary.

 

Specifications

  • High pressure welded construction, economic model
  • Threaded process connection for direct mounting
  • Whether proof to IP 68 per IS/IEC 60529:2001

Display TypeAnalog
Pressure TypeDifferential Pressure
ShapeCircular
The Magnehelic gauge is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems.

It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment.

Select the Magnehelic gauge for high accuracy, guaranteed within 2% of full scale. Designed for air and non-corrosive gases, 81 models are available to suit any requirement.

Using Dwyer's simple, frictionless Magnehelic gauge movement, this range of products quickly indicates low air or non-corrosive gas pressures - positive, negative (vacuum) or differential.

These gauges resist shock, vibration and over-pressures and contain no manometer fluid to evaporate, freeze or cause toxic or leveling problems.

They are very budget friendly as well!

Design features include a breakage resistant glass, easy-to-see red tipped pointer, near frictionless movement of internal mechanisms, a zero adjustment screw that can be accessed without removing the cover, resistance to overpressures, O-ring seal and die-cast iridite-dipped aluminium cases that have passed a 168 hour salt spray corrosion test.

Features : Magnehelic Gauge
  • Bezel with flange for flush mounting in panel
  • Breakage resistant clear plastic face
  • Precision litho-printed scale
  • Shock-resistant jeweled bearings
  • Easy access to zero-adjustment screw
  • Motion dampening with high viscosity silicone fluid
