Description:

The type 4392 level probe is a 2-wire 4~20mA submersible transmitter used for the hydrostatic measurement of levels in liquids.
The pressure is converted into an electrical signal.

Features:

  • Measuring ranges: 0...250 mbar to 0...25 bar
  • Medium temperature: 0...+50°C
  • Piezoresistive silicon probe
  • Excellent long-term stability
  • High overload resistance
  • Integrated surge voltage protection
  • Indirect cable breakage monitoring
  • Sturdy level measurement probe for indoor and outdoor applications
  • Optional with integrated Pt 100 temperature probe

Applications

Level and filling level measurement in

  • water and waste water management
  • well and surface water
  • disinfection plants with chlorine and chlorine dioxide
  • aggressive media (e.g. electro-plating baths, acids)


Common Model Examples:

Jumo Level Probe, 0~0.25 BAR=Approx 2.5m Water, 10 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~0.4 BAR=Approx 4m Water, 10 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~0.6 BAR=Approx 6m Water, 10 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~1 BAR=Approx 10m Water, 30 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~1.6 BAR=Approx 16m Water, 30 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~2.5 BAR=Approx 25m Water, 30 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~4 BAR=Approx 40m Water, 60 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~6 BAR=Approx 60m Water, 100 Meter Cable, 4-20mA Loop Powered
Jumo Level Probe, 0~10 BAR=Approx 100m Water, 100 Meter Cable, 4-20mA Loop Powered

The 404392 Replaces Older Model 404390

Note: Other ranges and cable lengths are available on request.
  Overvoltage protection:
LPN-OVP-E We strongly recommend that an overvoltage protection device is used with the JUMO 4392 / 4391 if long runs of cable are involved in the installation; to protect against potential Lightning strike or earth potential rises.
  Accessories:
Terminal Housing Terminal Housing with pressure equilibration (Pt No 00061206).
Cable Holder Cable Holder (Pt No 00061389).
