The Ramsey CAP Series controls detect the presence or absence of material by sensing a change in capacitance, which is caused by the difference in dielectric constant of the vessel material and air. To detect these small changes, the Ramsey CAP Series sensors use a unique detection circuit that operates at a relatively low frequency level of 6 kHz. Unlike other capacitance sensors, the operating frequency of the Ramsey CAP Series is well below the RF level and is not subject to FCC regulation. These capacitance level controls have a fail-safe feature that eliminates problems caused by power disruptions. Their high/low selector switches allow the sensors to be set for fail-safe at low when material is absent, or at high when material is present. When a power interruption occurs, the control will indicate the condition that the user deems safe for the application.
