The 25 GHz (K-band) non-contact level transmitters are recognized as innovative solutions in the industrial process automation field. With excellent accuracy and simple, cost-effective installation, these transmitters feature short and narrow antennas. Their versatile housing concept offers options in plastic, aluminum, and stainless steel, with antenna variations including stainless steel horn or parabolic planar antennas, as well as enclosed plastic tube varieties. The enclosed antenna versions allow for easy replacement without removing the antenna enclosure from the process. Local programming is facilitated by a plug-in display module, offering flexibility for on-site adjustments and potentially reducing the cost of ownership.

Non-contact microwave level transmitters operate by measuring the time it takes for a microwave burst to travel and return. Microwave impulses propagate at consistent speeds through air, gases, and vacuum, regardless of temperature or pressure, ensuring that the measured distance remains unaffected by medium-specific parameters. During operation, the level transmitter emits microwave impulses via its antenna, with a portion of the energy bouncing off the measurement surface and returning as reflected signals. The electronics within the transmitter process the time taken for these signals to return, converting it into distance, level, or volume data.

The ability to measure the level of a particular medium depends on the strength of the reflected microwave impulses, which is influenced by factors such as the distance to be measured, the relative dielectric constant of the medium, and surface turbulence. For optimal performance, the medium's relative dielectric constant (εr) should exceed 1.4 for parabolic design antennas or 1.9 for horn antenna types.
