Ultrasonic Level Sensor LUC-M20

LUC-M20
  • Device for non-contact level measurement
  • Measuring range up to 8 m in fluids
  • Measuring range up to 3.5 m in bulk materials
  • Quick and simple commissioning via menu-guided onsite operation with four-line display
  • Optional remote display and operation (up to 20 m from transmitter)
  • Integrated temperature sensor for automatic correction of the temperature dependent sound velocity

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.

Technische gegevens  LUC-M20

General specifications
Measuring methodThe sensor of the device transmits ultrasonic pulses in the direction of the product surface. There, the ultrasonic pulses are reflected back and received by the sensor. The device measures the time between pulse transmission and reception. The instrument uses the time (and the velocity of sound) to calculate the distance between the sensor membrane and the product surface. As the device knows the empty distance from a user entry, the device calculate the level.
Equipment architecture4 ... 20 mA output with HART protocol
Construction typecompact device

Input
Measured variabledistance between the sensor membrane and the product surface
using the linearization function, the device calculate
- level in any units
- volume in any units
- flow across measuring weirs or open channels in any units
Measuring rangemax. 8 m (26.2 foot) in fluids
