LTDR Measurement Transmitter

Level measurement independent of changing process conditions (density, conductivity, temperature, pressure,…)

Innovative signal analysis and disturbance signalsuppression

Almost no installation restrictions Different types of probes: single rod, coaxial and rope probe, interchangeable thanks to its modular design

Suitable for almost every liquid. Exceptional performance in liquids with low dielectric constant (i.e. low reflectivity) such as oils and hydrocarbons

Suitable for solids, mainly with rope probe version. Unmatched price / performance ratio.

Measuring range: 

  • Single rod probe: 100 ... 3000 mm
  • Coaxial probe: 100 ... 6000 mm
  • Rope probe: 1000 ... 20000 mm

Connections:

  • Rosca G¾A or G1A threaded connection
  • EN 1092-1 DN40 flange or bigger

Materials:

  • EN 1.4404 (AISI 316L),
  • PEEKTM 4-20 mA output
  • 1 x programmable transistor output for level detection

Optional:

  • ATEX version
  • Extended

More Information

LTDR uses TDR (Time Domain Reflectometry) technology. Low-energy, high-frequency electromagnetic impulses, generated by the sensor’s circuitry, are propagated along the probe which is immerged in the liquid to be measured. When these impulses hit the surface of the liquid, part of the impulse energy is reflected back up the probe to the circuitry which then calculates the fluid level from the time difference between the impulses sent and the impulses reflected. The sensor can output the analyzed level as a continuous measurement reading through its analog output, or it can convert the values into freely positionable switching output signals. LTDR Sensors are also known as Guided Radars or Guided Wave Radars.
