General The Bulletin Conductive Liquid Level Control is designed to provide a reliable level detection of conductive liquids or solids. No moving parts or floats are required. Metal probe rods are placed in the conductive liquid at the desired levels. The liquid or solid conductive material completes the circuit between the probe rod or rods to the metal material container. If the container is non-conductive (fiberglass, cement, etc.), an additional probe rod is used as a grounding probe to complete the electrical circuit. Completion of the circuit will cause the output relay to operate. The relay contacts may be used for pump, valve, or motor control; audible and/or visual level indication. The controls will operate over a resistivity range of 0 to 60 MegOhms-cm. This permits the sensing of liquids or solids with very low conductivity such as antibiotics, refrigerants, or sand with a moisture content as low as 5%. In addition to high sensitivity, the control has a fast response time and can be wired for electronic control latching on certain applications, allowing the use of both sets of relay contacts for external loads. A solid state output signal can be obtained from the control simultaneously with a relay output. This signal can be used for electronic counting, data logging, or feeding information to a computer. The control has protection against false operation due to line voltage transients, line voltage dropouts of / second or less, or during initial power up. These features allow the Control to be used in solving the more difficult industrial level applications. Resistance Sensing Control Photoswitch Bulletin 3DJ3 is also designed to be used as a resistance sensing control. In this application the control operates as an electronic switch which converts the minute current flow through delicate mechanisms or extremely light contacts into a switching output capable of handling relatively heavy electrical loads. The maximum sensitivity of the control when used for resistance sensing is 5 megohms.

The probe assembly consists of a probe fitting threaded for convenient installation into a tank, vat, or other container; a stainless steel probe rod or insulated suspension wire which may be cut to the desired length for the particular installation; and a probe tip designed to provide the required surface area at a point of contact with the liquid. Figure shows typical probe assemblies. Series 6 probe fittings are ceramic insulated with stainless steel trim which may be used either alone or in one of a variety of metal enclosures. Single and double probe fittings are available. Series 63 sanitary probe fittings are available for dairy and other food processing installations. Sanitary probes do not require probe tips for satisfactory operation. Series 6 probe tip assemblies are combinations of a probe rod or suspension wire of the desired length with a suitable probe tip and are used with all Series 6 probe fittings.

Rods may be ordered to size, or may be supplied longer than required and cut to the desired length. One end of the rod is threaded for connection to the probe fitting. The unthreaded (cut) end should be inserted in the probe tip and held by means of a set screw. For deep well and other long probe applications over 0 (3m), suspension wires and tips should be installed. Standard probe tip 6-388, is used with all probe rods. Special probe tip 6-38 with insulating sleeve, is used with suspension wire. The probe rod or suspension wire adaptor 6-385 is connected to the probe fitting as follows: 6 Series fittings have a / -0 female thread to receive the / -0 male thread of the probe rod or suspension wire adaptor. When the long probe of any multiple probe assembly is over 30 (.76m), a Teflon insulating spacer 3 -, is fitted over the short probe rod immediately above the probe tip to prevent the rods from touching. For suspension wire assemblies, an insulating sleeve fits over the probe tip to prevent it from touching other surfaces. Series 63 sanitary probes for dairy and food industry applications are made for special sanitary fittings. The probe insulator is made to fit a #5 union ferrule and to be secured with a #3H union nut. The ferrule and nut are supplied by the customer and are soldered, brazed, or otherwise secured before insertion of the probe assembly. Probes 63GH and 63GH fit -/ ferrule, while probes 63GJ and 63GJ fit a ferrule. All Series 63 probe rods are 3 (.9m) long and are to be cut to length on the job. Mounting 3DJ3 controls may be mounted in any position on a sturdy wall, partition, panel board, bracket, or similar support. While the NEMA enclosure is being mounted, the control base should be stored in a safe place to avoid moisture and mechanical damage. The enclosure mounting hole dimensions are shown on page and sheet metal, wood or machine screws, bolts, or similar fasteners may be used. When the housing has been securely fastened, connect the cables or conduits to the housing in the knock out holes provided and replace the control base. 9
The wiring between the control and the probes should not exceed the lengths listed below. Table 8: Maximum Recommended Cable Length CABLE LENGTH 000 (609.6m) 000 (30.8m) 3 500 (5.m) 000 (609.6m) 5 000 (609.6m) 6 50 (5.7m) Resistor Selection Wiring When the resistivity of the liquid is known, convert to ohms cm and select the range resistor that corresponds to the resistivity range in Table 5. When the resistivity of the liquid is not known, immerse the high level probe tip /6 (.5mm) into the liquid. For operation with the relay energized with the probe immersed, connect the Range resistor (330 ohms) to Terminals and. The relay should energize. If it does not, use successively higher range resistors until the relay energizes. If relay action is sluggish, use the next higher range resistor. For operation with the relay de-energized with the probe immersed, connect the Range resistor (330 ohms) to Terminals and 3. The relay should de-energize. If it does not, use successively higher range resistors until the relay de-energizes. If relay action is sluggish, use the next higher range resistor. Note: For resistance sensing applications, use the values of resistance sensing sensitivity listed in Table 6 in place of probe circuit resistivity for selection of the proper range resistor. Note: Wiring for Ranges --3 differs from Ranges -5-6. Follow wiring instructions in Wiring Diagrams in Figures 6-. All external wiring should conform to the National Electric Code and applicable local codes. See wiring diagrams for external connections. Wire no smaller than 6 AWG is recommended. WARNING: Do NOT run probe or reset leads in same conduit with power lines or high current carrying conductors. Since the 3DJ3 control operates with liquids having high electrical resistance, the insulation resistance of the wiring connecting the control to the probe must be extremely high. It is important, therefore, to use plastic insulated wire to insure that the insulation will not absorb moisture or crack and permit leakage paths to develop. Wires insulated with paper, cotton, asbestos, etc. must not be used. Series 63 sanitary probes are furnished with a molded separable connector and 0 (3m) cable assembly. 0
