Nivelco Microwave Level Measurement Products
Nivelco PiloTREK Compact Radar Level Measurement
The 25 GHz (K-band) PiloTREK Pulse Radars are regarded as the most progressive non-contact level transmitters of the industrial process automation field. Their accuracies are excellent and their short and narrow antennas make their installation simple and low-cost.
NIVELCO’s K-band radar featuring ±3 mm (0.12 inch) accuracy and short dead band excels with its versatile housing concept lining up plastic, aluminum and stainless steel versions. Its antenna range incorporates stainless steel horn or parabolic planar antenna and enclosed plastic tube varieties.
The enclosed antenna versions can be replaced without removing the antenna enclosure from the process. Local programming of the PiloTREK is aided by a plug-in display module. If on-site reading is not desired this module may not be required thus reducing the cost of ownership.
The signal processing algorithm of the PiloTREK is based on NIVELCO’s 35 years of experience with non-contact level measurement making it an excellent choice for applications simple and challenging alike
OPERATION
The operation of the non-contact microwave level transmitters is based on the measurement of the time of flight of the microwave burst. The propagation speed of microwave impulses is practically the same in air, gases, and in a vacuum, independently from the process temperature and pressure, so the measured distance is not affected by the physical parameters of the medium to be measured.
The level transmitter induces microwave impulses a few nanoseconds long in the antenna and a part of the energy of the emitted signals is bounced (reflected) back from the measurement surface depending on the measured media. The time of flight of the reflected signal is measured and processed by the electronics, and then this is converted to distance, level or volume proportional data.
The measurability of the level of a specific medium is depending on the signal strength of the reflected microwave impulses. The signal strength of the reflected impulses is considerably dependent on the distance to be measured, the relative dielectric constant of the measured medium, and the turbulence of the surface. The relative dielectric constant (?r) of the medium should be more than 1.4 in the case of parabolic design, or it should be more than 1.9 with horn antenna types.

Nivelco PiloTREK W–200 Compact Radar Level Measurement
The PiloTREK W–200 families of new 80 GHz non-contact radar level transmitters use industrial measurement technology’s most advanced, state-of-the-art measurement method. It implements uncompromising, state-of-the-art level measurement technology for liquids, emulsions, and other media widely used in, for example, the food & beverage, energy, pharmaceutical, chemical, and marine applications, providing measurement results with mm accuracy.
It is also excellent for measuring substances prone to vapor formation and liquids with gas cushions. In addition to the level, volume, and weight measurement functions, this product family also inherits the open-channel flow measurement functions and the threshold functions to eliminate flexible and interfering echoes introduced in connection with ultrasonic devices. Since no medium is required for millimeter waves to propagate, it can also be used in a vacuum.
The device can also be operated with HART® compliant NIVELCO EView2, MultiCONT universal process controller, and PACTware software.
OPERATING PRINCIPLE
The reflection of the millimeter waves is highly dependent on the dielectric constant of the medium. Therefore, the measured medium’s dielectric constant (er) must be over 1.9 for millimeter-wave level measurement. The measurement principle of a level transmitter with a millimeter-wave signal is based on measuring the reflection’s time of flight. The speed of propagation of millimeter-wave signals in the air, gases, and vacuum is almost constant regardless of temperature and medium pressure, so the measured distance does not depend on the physical parameters of the intermediate medium.
The PiloTREK W–200 level transmitter is a continuous wave frequency modulated radar (FMCW) operating at 80 GHz (W-band). The most obvious advantages of 80 GHz radars over lower frequency (5…12 & 25 GHz) radars are smaller antenna size, better focus, and smaller beam angle.
A portion of the millimeter-wave continuous wave energy radiated by the level transmitter antenna is reflected from the measured surface, depending on the material to be measured. The distance of the reflecting surface is calculated with high accuracy by the electronics from the frequency shift of the reflected signal and converted into a distance, level, or volume signal by the electronics.
