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).
