Datasheet excerpt: Technical data of LVL-M2C
| General specifications | ||
|---|---|---|
| Function principle | limit detection Maximum or minimum detection in tanks or pipelines containing all types of liquids including use in explosion hazardous areas. Particularly suited to very aggressive liquids thanks to high degree of corrosion protection. |
|
| Measuring method | The forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid. The change in frequency then activates the limit switch. |
|
| Construction type | device with extension tube, coated with ECTFE | |
| Series | LVL-M* | |

| Measurement range | depends on mounting point and pipe extension up to 3000 mm , larger sizes on request | |
| Output | ||
| Switching delay | when fork is covered: approx. 0.5 s, when fork is exposed: approx. 1.0 s (other switching times on request) additionally configurable for PROFIBUS PA (electronic insert FEL50A (PA)): 0.5 ... 60 s |
|
| Switch behaviour | switch-over for minimum/maximum residual current safety on electronic insert MAX = maximum safety: The output switches to the power fail response when the fork is covered. for use with overspill protection for example MIN = minimum safety: The output switches to the power fail response when the fork is exposed. for use with dry running protection for example When switching on the power supply the output assumes the alarm signal. After max. 2 s it assumes the correct switching mode. |

Details: LVL-M2C
Function
The device is a limit switch for use in all liquids
-
for temperature from -50 °C to +120 °C
-
for pressures up to 40 bar
-
for viscosities up to 10000 mm 2/s
-
for density up to 0.5 g/cm 3 (other settings available on request)
The function is not affected by flow, turbulence, bubbles, foam, vibration, bulk solids content or build-up, the device is thus the ideal replacement for float switches.
The device is available with extension tube up to 3 m (larger sizes on request).
The coating of all device wetted parts (process connections, extension pipe and vibration fork) is made of synthetic material to ensure it can be used for highly aggressive liquids.
Devices with protection Ex ia and Ex d are available for use in explosion hazardous areas.
