Level Switches

NAB

Float Level Switch

The KOBOLD NAB is a compact and robust float-level switch designed for point-level detection in liquids-ideal for tank monitoring and pump control. It features a polypropylene float that actuates an SPDT (tilt-based) mechanical switch, offering reliable on/off level control with high current capacity.

• Material: Polypropylene
• Pmax: 3.5 bar
• Tmax: 85 °C
• Cable length: up to 20m
• Protection type: IP 68

ERH

Float Level Switch

The ERH is a robust switch designed to detect liquid levels using a magnetic float inside a switching chamber. When the float rises or falls, magnetic actuation triggers limit switches safely through the housing-eliminating the need for wiring through the tank wall

• Explosion proof version
• Pressure: 40 bar
• Protection: IP 66/68
• Material: Aluminum or st-steel

JUMO NESOS R03 LS

Float Bypass Switch

The JUMO NESOS R03 LS is a robust point-level switch designed for liquids, featuring a built-in reference chamber. It operates on Archimedes’ principle, where the float rises or falls with the liquid level within the chamber, triggering one or two reed-contact switches.

• Capacity: Up to 250 V AC/DC; up to 1 A
• Temperature: -30 to +150 °C
• Pressure: -1 to +6 bar
• Density: 700 to 1400 kg/m³
• Protection rating: IP 66

NES

Conductive Level Switch

The KOBOLD NES is a reliable conductive level switch designed for monitoring and controlling the level of conductive liquids. Its design without any moving parts makes it suitable for applications involving critical media, such as those with solid content, negligible density, or high viscosity.

• Contact: 5 contacts via relays
• Connection: G ½ ; G 1½
• Pmax: 30 bar
• Tmax: 150°C
• Material: stainless steel; Hastelloy®; titanium

NWS

Tuning Fork Level Switch

The KOBOLD NWS is a reliable vibrating fork level switch designed for detecting the presence or absence of liquids in tanks and pipelines. Utilizing the tuning fork principle, it offers accurate and maintenance-free operation, making it suitable for various industrial applications.

• Contact: 1 electronic switch
• Connection: Various
• Pmax: 45 bar
• Tmax: 130°C
• Viscosity: up to 5000 mm²/s
• Material: st-steel
