Electrical Conductivity or Resistance Liquid Level Switches Datasheets

The LL20-OW from Arjay is designed specifically to monitor for situations that may have a water or oil intrusion into a dry space.[See More]

• Measuring Range: ? to 12.00 inch
• Pole & Throw: Single Pole, Double Throw (SPDT) 

• Construction: Electro-mechanical switch 
• Maximum Current: 10.00 amps

Conductivity liquid-level controls are designed for use in electrically conductive liquids. When the liquid contacts the tip of the probes they act as a switch closure and can be used for pump or solenoid control, high and low alarm contacts or heater protection.[See More]

• Construction: Solid-state switch 
• Pole & Throw: Single Pole, Single Throw (SPST) 

• Configuration: Normally Open (NO) 
• Maximum  Pressure: 250 psi

• Measuring Range: 157 to 591 inch
• Configuration: Normally Open (NO) 

• Construction: Solid-state switch 
• Pole & Throw: Single Pole, Single Throw (SPST) 

The NEK series compact conductive level switch is an excellent choice for monitoring the level of conductive liquids in tanks. The NEK series conductive level switch senses liquid level by applying a low AC voltage to a set of stainless steel electrodes.[See More]

• Construction: Solid-state switch 
• Pole & Throw: Single Pole, Single Throw (SPST) (optional feature) 

• Configuration: Normally Open (NO) 
• Maximum Current: 1.00 amps

The BM 500 level gauge operates on the potentiometric measuring principle and is designed for use in all electrically conductive products with a minimum conductivity of 1 µS/cm (e.g. distilled water).[See More]

• Measuring Range: 7.20 to 120 inch
• Maximum  Pressure: 232 psi

• Repeatability: 0.1000 +/-inch
• Material Temperature: -4 to 284 F

Sitron's model CLF (1 up to 5) level switch is the most commonly specified conductive level switch. The CLF (1 up to 5) can accommodate up to five 316S.S. fixed rods for five (or more upon request) different levels of control. The rods are isolated with a PTFE joggle and can also be coated with PTFE...[See More]

• Measuring Range: 2.00 to 79.00 inch
• Construction: Electro-mechanical switch 

• Repeatability: 0.0394 +/-inch
• Pole & Throw: Single Pole, Double Throw (SPDT); Uses An External Controller 

The Model FSI Float Switch Indicator displays the status of up to 5 float switches. When a float switch closes, the corresponding LED lights. When a float switch opens, the corresponding LED goes out.[See More]

• Construction: Electro-mechanical switch 
• Switch Points: 1.00 to 5.00 #

• Pole & Throw: Single Pole, Single Throw (SPST)
