OVERVIEW
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)

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). -
