Level Float Switch - LEN Series The electromagnetic level indicator activates an electric signal when the fluid inside the tank reaches a stated level.

2 Level Float Switch - LEN Series The electromagnetic level indicator activates an electric signal when the fluid inside the tank reaches a stated level. LEN series is available with three hole flanges or with a 1" BSP threaded connection, with 1 or floats, in a standard range of lengths. 5-1 The float traveling up and down the tube contains a magnet: when the float reaches the reed switch enclosed in the tube, the magnet causes the contact to close (or open). Technical Data Materials: Connector: Plastic Flange: luminum Tube: Brass Float: Plastic Electrical Data: N.C. to N.O. Conversion: Working Pressure: Working Temperature: Warning: Power communicable to DC: 60W Power communicable to C: 80V DC current intensity: 1.3 C current intensity: Communicable voltage: 50V Frequency: 50 Hz/60 Hz Capacitance of open contacts: 4pF Insulation resistance 10 ohms Connector protection: IP 65 To convert an "LEN" from N.C. to N.O. or vice versa, remove the bottom "C" clip on the rod, turn the float upside down and replace both the float and "C" clip. 40 PSI For higher pressure, please consult Technical Dept. From -0ºC to +100ºC These indicators are designed for vertical installation. The float must be at least 35 mm away from any ferrous surface.

5 Level Float Switch - RL Series Rapid Level Float Switch. Revolutionary new series of electro-magnetic level gauges. Packed in "Kit" form. Only a few seconds are required to obtain the desired length: just cut the control rod to length. There are no electrical components submersed in the fluid. Can be used in heavily contaminated fluids and refrigerating oils. Tolerates the presence of metallic particles. Multiple switching options are available to customize your system. Models suitable for high temperatures and corrosive liquids are available. 5-4 Technical Data Wiring Schematics: (absence of fluid) S1 1 S 3 S3 ELECTRICL CONNECTOR LOCTION SEL PCKING OR GSKET POSITION SWITCH (S) S3=S1+S1 Switch Specifications: Exchange Contact Switch: Open or closed contacts switch Standard: 3. 60W. 60 V.. 50V On request: V. 50V 1 30W. 60 V.. 0V 1 POSITION SWITCH (S1) MGNET Mounting Pattern F3: COMPRESSION JOINT CONTROL ROD (WITH FLOT ND MGNET SSEMBLED) Ø34.6 LR - F3 QUICK MOUNTING ROD/FLOT CONNECTOR FLOT (IN PLSTIC) Each level is supplied outfitted with screws and oiltight gasket

7 RL/G1 Series - Single Float Packed in a kit form which includes the head/ connector assembly, control rod and float. CONNECTOR REED- CRRYING HED (NYLON GLSS) 8mm 15mm Switches are in the head assembly thus there are no wires to position inside the control rod. The control rod is stainless steel and can be cut to length easily. The float is fixed to the control rod and does not contain any magnets. This eliminates the collection of ferrous material present in some fluids. The control rod and float move as one piece into the head assembly to actuate the switches. Standard model is supplied with control rod closing the switch with falling oil level. If you need open contacts add "" to the standard code. ie: RLG1-F3-S3 "" L Level CONTROL ROD (STINLESS STEEL) FLOT (PLSTIC) 1-1/4" NPT 55mm For lengths over 500 mm or in systems with turbulence in the tank, specify type "R" reinforced rods. Mounting connection: T3: 1-1/4" NPT thread F3: Flange 3 mounting holes 5-6 RL/G Series - Double Float 8mm 15mm The RL/G's head accepts two control rods. Each control rod activates a separate switch. Each switch can be wired with S1, S, S3, configuration. This option allows a wide variety of signal options. For lengths over 500mm or in systems with turbulence in the tank, specify the "R" reinforced rod. L L1 The standard model is supplied with control rod 1 closing the switch contacts with falling oil level and control rod closing the switch contacts with rising oil level. For open switch contacts add "" to the standard code. Mounting Connection: T3 = 1-1/4" NPT thread F3 = Flange, 3 mounting holes.

RL/L Series - Side Mount Rapid Level lateral electro-magnetic levels packed in "Kit" form. 5-7 This model mounted on the side of the tank, has the same basic design as the tank top version.

8 RL/L Series - Side Mount Rapid Level lateral electro-magnetic levels packed in "Kit" form. 5-7 This model mounted on the side of the tank, has the same basic design as the tank top version. Unlike the tank top models, the distance between the first and second signal is not fixed. s the length of the control rod increases the distance between the two signals increases (see graph). Example using graph: The hydraulic pump is allowed to operate through the cross hatched range. When the oil level reaches line 1 a low oil level warning signal is generated. When the oil level drops to line 3 the system is automatically shut down.
