JUMO NESOS R40 LSH Level switch horizontal

Applications

• Point level measurement of liquids in storage tanks, containers, oil sumps, and tanks
• Water and wastewater treatment
• Mechanical and plant engineering
• Apparatus and container engineering
• Oil and gas
• Chemical and petrochemical industries

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.
The float switch is mounted at the side (horizontally) on a tank or container, for example. This means that the same product can be used for applications involving both a minimum (MIN) and a maximum (MAX) point level. On versions with threaded process connections, the float is aligned using a cutting ring fitting. Float switches with highly configurable guide tube lengths of up to 1 m are available for applications involving container insulation or flange fittings. Variants with a connecting plug help to minimize mounting work. 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), SPDT-CO (Changeover contact).

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 exam- ple
• Reduced operating costs due to maintenance-free device design
• No isolating switch amplifier required for [Ex] (flameproof enclosure) applications
• Lower storage costs as the same component can be reused
