Local and remote monitoring for cryogenic pressure vessels

  •  Local and remote level monitoring of small cryogenic pressure vessels (vertical and horizontal)
  • Integrated differential pressure transducers
  • LCD display for level visualization in %
  • Output signal 4-20 mA
  • Level sum function available on 4-20mA output
  • Powered by 4-20mA loop or battery operated with 4-20 mA loop disconnected
  • Sampling rate 3 minutes with battery or real time when loop powered
  • Selection of differential pressure range by push-buttons behind the front panel
  • Easy, quick and inexpensive installation

Optional Telemetry functions:
  • Low power data transmission technology: NB-IoT or SigFox
  • Remote programming by CrioSystemSupervisor platform
  • Remote transmission and notification of low level alarm
