Monitor's NEW PAC-30 and PDC-30 Proximity Level Switches are an economical and reliable alternative for many point level applications. These RF capacitance-based switches detect either the presence or absence of material at a pre-determined point within a vessel to provide high or low level indication. The PAC-30/PDC-30 switches can detect a wide range of materials from metallic and non-metallic dry bulk solids to liquids. The PAC-30 is AC operated (20-250 VAC) and is available in either a normally open or normally closed configuration. The PDC-30 is DC operated (10-40 VDC) and is available in either PNP or NPN configuration, each of which can be wired in either a normally open or normally closed mode.
