series level sensors designed point indication conductive liquids. Used conjunction with more RCU7000 relays (see Controllers section RCU7000 specifications), series reliably detect separate levels tanks seven feet deep. Operating levels easily changed field cutting length electrodes. standard electrodes manufactured from 316SS. applications with unique chemical compatibility problems contact information about electrodes titanium Hastelloy
series switches used suitable, conductive liquid. Applications involve both alarm point detection pump valve control. Standard electrodes available with switch long lengthened simply screwing each extension electrode. Since system contains moving parts very reliable used tanks where mixers other moving equipment would damage ordinary float switches level detectors.
Intrinsic Safety
conductive level controls used with Intrinsic Safety Barriers (IS) meet hazardous location requirements level control device.
