KUM-A ultrasonic water level sensor

Brief introduction of ultrasonic level sensor

This ultrasonic sensor provides very short to long-range detection and ranging, in a compact, robust PVC or stainless steel housing, designed to meet IP67 water intrusion. The power 9.0V-28V operation detects objects from 0.1meters to 10meters and provides sonar range information from 0.25meters out to 10meters out with 0.001meters or 0.01meters resolution. The interface output formats included are pulse width output, analog voltage output, NPN/PNP output and serial digital output.

Features of long range ultrasonic leve sensor

  • High sensitivity
  • Designed for outdoor or indoor environments
  • 9V-28V supply with very low average current draw
  • Sensor operates at 40 KHz, 112 KHz, 175 KHz, 300 KHz, 1 MHz
  • Free run operation can continually measure and output ranger information
  • Multi-kind output type such as analog (40-20mA, 0/1-5V, 0/1-10V), RS485, Can bus.
  • Readings can occur up to every 33mS(30Hz) within 3meters or occur up to every 80ms(12.5Hz) within 10meters.
