OMEGA's intrusive RF capacitance sensors deliver accurate and reliable liquid level detection with an FET switch, 4 or 20 mA, TTL or voltage output. RF capacitance technology provides a high level of dielectric sensitivity, including new technology, which improves resistance to coating and scaling.
The sensor is impervious to variations in temperature, pressure, light, particulates, liquid color or density. Factory calibration ensures reliability with a wide range of polar liquids.
