Description Technical Specifications Downloads Vendor

HT- H2 pressure sensor

  • The piezoresistive stainless steel measuring cell has especially been adapted to suit the chemical and physical properties of hydrogen.
  • The entire sensing element is made from of a single piece without welds, which is designed to prevent embrittlement of the metal surface by ionized hydrogen.
  • Completely vacuum tight and elastomer free.
  • Leaks caused by material fatigue on internal seals are thus eliminated from the outset.
  • Has no disturbance due to pressure transfer fluid and no large pressurized surfaces.
  • The link into the connection pins are made by wedge wedge bonding and is therefore completely stable even at low temperatures, or when subject to shocks or vibrations.
  • The measuring bridge evaluates the pressure via a mixed signal ASIC. The HT-H2 can also be used for other critical media.

Features

  • Working pressure ranges from 0 to 1000 bar
  • Wide range of threads inc. ¼” & ½” NPT, 9/16-18UNF, 3/8-24 UNF 2A, G1/4 & G1/2
  • Outputs, 4-20mA, 0.5-4.5V rat., 0-5V & 0-10V
  • SS316L wetted parts
  • Medium-contacting parts of stainless steel 1.4404/316L
  • Response time < 1ms
  • Approval options: ATEX & EC79
  • Standard elec. conn. options: Packard Metri-pack, AMP Superseal, Deutsch 3P & 4P, M12x1, DIN Form A

Applications

  • Hydrogen storage
  • Hydrogen refueling
  • Hydrogen production
  • Hydrogen fuel cells

Use cases

  • Monitoring the cylinder pressure in vehicle storage tanks
  • Monitoring the delivery pressure in refueling systems
