| The ELS series of level sensors are designed for point indication of conductive liquids. Used in conjunction with one or more RCU7000 relays (see Controllers section for RCU7000 specifications), the ELS series can reliably detect up to 7 separate levels in tanks up to seven feet deep. Operating levels can be easily changed in the field by cutting the length of the electrodes. The standard electrodes are manufactured from 316SS. For applications with unique chemical compatibility problems contact Automation Products Group, Inc. for information about electrodes in titanium or Hastelloy B and C. |

| A typical system consists of three major components. An electrode holder, the electrodes and a relay unit. The electrode holder serves as a mechanical support for the electrodes and electrically insulates them from the tank. The electrodes are vertically mounted to the holder, above the liquid, with their lower ends positioned at the required actuation levels. The relay unit provides the voltage and current required (8 VAC, 5 mA max.) for sensing as well as suitable relay outputs. |
| The ELS series switches can be used in any suitable, conductive liquid. Applications involve both alarm point detection and pump valve control. Standard electrodes available with the switch are 39 in. long and can be lengthened by simply screwing on each extension electrode. Since the system contains no moving parts it is very reliable and can be used in tanks where mixers or other moving equipment would damage ordinary float switches or level detectors. |
