Kromschroder DG Pressure Switches for Air and Gas Pressures

Featuring the ability to observe extremely low pressure differentials, Kromschroder's DG pressure switches trigger switch-on, switch-off, switch-over operations if a set switching point is reached. They monitor positive and negative gas and air pressures in industrial and commercial applications.

Key Specifications

  • Applications in monitoring positive air and gas pressures, negative or differential air pressures
  • Five pressure ranges from 0.2" to 200" WC (0.5 mbar to 500 mbar)
  • Accurate, repeatable switching action with low hysteresis
  • Automatic and manual reset models available
  • One normally open and one normally closed contact in each switch (5A resistive or 0.5A inductive)
  • 8A quick-acting fuse for short circuit protection
  • FM and UL approved
