JUMO NESOS R04 LS Level switch bended
Description
Measurement applications
- Point level measurement of liquids in storage tanks, containers, oil sumps, and tanks
- Water and wastewater treatment
- Mechanical and plant engineering
- Shipbuilding
- Energy technology
- Diesel tanks
- Possible to made for customer specific purposes
Short description
The point level measurement is carried out according to Archimedes’ principle for liquids. The float moves along the guide tube as the level rises or falls. The magnet in the float actuates the reed contact(s) installed in the guide tube with its magnetic field. The switching status of the reed contact can be evaluated and processed through downstream electronic components, relays, or contactors. Alarms, pumps, signal lamps, valves, and horns are typically switched via a contact protection relay.
Float switches of up to 2 m in length and with up to 5 switching points are available for applications involving high filling heights. The product is installed on the side of the tank or container wall and, in the case of versions with a thread, it is fixed with a lock nut. Depending on the variant ordered, various electrical connections, process connections, guide tube lengths, floats, number and positions of contacts as well as their function (SPST-NO (Normally open), SPST-NC (Normally closed), SPDT-CO (Changeover contact) and bistable contacts are available.
Optional temperature sensor
With the optional temperature sensor or temperature switch, both the point level measurement and the temperature can be acquired via just one measuring point. Variants for monitoring the reed contact temperature are also available.
Explosion-proof
The JUMO NESOS R04 LS can also be delivered according to EX i (intrinsic safety) or EX d (flameproof enclosure) standards in connection with explosion proof environments. With an Ex d version, no Zener barrier or insulator is required in the control cabinet.
Customer benefits
- Cost-effective installation and mounting, due to spring-cage terminals (Push-In®), for example
- Reduced operating costs due to maintenance-free device design
- No isolating switch amplifier required for Ex d (Flameproof enclosure) applications
