1 Vibration Limit Switch Features Limit switch for liquids External function test with test magnet Onsite function check possible thanks to LED indication Large selection of process connections for hassle-free installation in existing systems Easy to install even at points difficult to access due to compact design Rugged stainless steel housing Suitable for process temperatures up to 50 C (0 F) Cost-saving plug connections pproval as overfill protection and leak detection system acc. to WHG ssembly 4 Function The Vibracon is a limit switch for liquids and is used in tanks, vessels and pipes. The device is used for overfill prevention or pump protection in cleaning and filter systems as well as in cooling and lubrication vessels, for instance. The device is suitable for applications in which float switches or conductive, capacitance and optical sensors have been used up to now. The device also works in areas where these measuring principles are not suitable due to conductivity, buildup, turbulence, flow conditions or air bubbles. The device can be used for process temperatures up to: - 00 C ( F) - 50 C (0 F) The device is not suitable for use in hazardous areas. For hygienic areas we recommend the use of Vibracon LVL 7H.

2 General specifications Measuring method Construction type Operating mode The tuning fork is brought to its resonance frequency by means of a piezoelectric drive. If the tuning fork is covered by liquid, this frequency changes. The electronics monitor the resonance frequency and indicate whether the tuning fork is freely vibrating or is covered by liquid. compact device device with short tube MX = maximum safety: The device keeps the electronic switch closed as long as the liquid level is below the fork. example application: overspill protection MIN = minimum safety: The device keeps the electronic switch closed as long as the fork is immersed in liquid. example application: dry running protection of pumps The electronic switch opens if the limit is reached, if a fault occurs or in the event of a power fails (quiescent current principle) Supply Rated voltage U n - DC-PNP: V DC, -wire - C/DC: V C/DC, -wire Current consumption - DC-PNP: < 5 m - C/DC: <.8 m Power consumption - DC-PNP: < 975 mw - C/DC: < 850 mw Input Measured variable density Measurement range min. 0.7 g/cm, optional> 0.5 g/cm Output Output type switch output Switching current max. 50 m Directive conformity Electromagnetic compatibility Directive 04/0/EU EN 66-:006, EN 66--:006 Low voltage Directive 04/5/EU EN 600-:00 Conformity Electromagnetic compatibility NE Degree of protection IEC 6059 Shock resistance EN Vibration resistance EN Climate class DIN EN /IEC Measurement accuracy Reference operating conditions - ambient temperature: 5 C (+77 F) - process pressure: bar (4.5 psi) - fluid: water (density: approx. g/cm, viscosity: mm /s) - medium temperature: 5 C (+77 F) - density setting: > 0.7 g/cm - switching time delay: standard (0,5 s, s) Measured value resolution < 0.5 mm Measuring frequency approx. 00 Hz in air Switching point mm ± mm Non-repeatability ± mm acc. to DIN 698- Hysteresis max. mm Influence of ambient temperature negligible Influence of medium temperature -5 µm/ C Influence of medium pressure Switching time Operating conditions Installation conditions Installation position mbient conditions mbient temperature Storage temperature Shock resistance Vibration resistance Process conditions Medium temperature Process pressure (static pressure) -0 µm/bar s when tuning fork is covered -.0 s when tuning fork is uncovered - other switching times on request see section mounting position C ( F) C ( F) a = 00 m/s = 0 g, planes x directions x shocks x 8 ms, as per test Ea a(rms) = 50 m/s, SD =.5 (m/s ) /Hz, f = 5 to 000 Hz, t = x h C ( F) C ( F) bar ( psi)
