Our advanced 2-wire capacitive level transmitters are designed for precise and reliable liquid level measurement across various industries, including chemical processing, water management, and food production. These transmitters use capacitive technology to determine the level of both conductive and non-conductive liquids by employing a probe and an optional reference probe. The basic principle revolves around changes in capacitance caused by the displacement of air by a medium within a tank, offering a robust method for fluid level detection.

The operational mechanism of these level sensors involves the creation of a capacitor between the probe and the reference probe (which can be the tank wall or a separate component). Initially, the capacitance (C0) is set with the tank empty, depending primarily on the air's dielectric constant and the positioning of the probes. As the tank fills, the capacitance increases proportionally with the liquid level

For optimal performance and accurate level measurements, it is essential that the change in capacitance directly corresponds to changes in the liquid level. This accuracy is best achieved with a coaxial probe setup, where the probes are parallel, minimizing the effects of distance variation between them.

The installation and calibration process of these capacitive level transmitters is straightforward. Technicians can "teach" the system the low and high limits of the tank’s capacity. This calibration can be performed at any level, not necessarily at the absolute maximum or minimum, thanks to the flexible indirect assignment feature. This feature is particularly useful in situations where full tank draining or filling is impractical.
