Ultrasonic Level Sensor LUC-M**

LUC-M**
  • Quick and simple commissioning via menu-guided onsite operation with four-line display
  • Envelope curves on the on-site display for simple diagnosis
  • Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate
  • Non-contact measurement method minimizes service requirements
  • Optional remote display and operation (up to 20 m from transmitter)
  • Integrated temperature sensor for automatic correction of the temperature dependent sound velocity

Function and system design
Measuring principleThe 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
system integration via PROFIBUS PA
