Solid-State Condition Sensors: 839E and 840E

839E and 840E Solid-State Allen-Bradley SensorsCondition Sensing controls are vital components in today's control systems. Hight-accuracy, new technology, and rigid standards are combined to manufacture these reliable world-class products. 

Rockwell Automation offers and impressive line of Allen-Bradley conditioning sensing products to meet your application needs. With models capable of detecting pressure, temperatures, flow, and level, Allen-Bradley solid-state and electromechanical condition sensing switched offer exceptional control for automatic operation of machines and processes. 

Solid-State 839E Flow Sensor

Allen-Bradley 839E flow sensors monitor and display liquid media flow rate in the range from 0.03 to 3 m/s(0.1 to 9.84 ft/s). Available with two deferent probe insertion length, this sensor is capable of measuring both flow and temperature. 

  • Rugged, corrosion-resistant 316L stainless steel housing with IP66 enclosure rating
  • Flow rates of liquid media (calorimetric measuring principle) in the range from 0.03 to 3 m/s (0.1 to 9.84 ft/s)
  • Four-digit 14-segment digital display
  • Dual N.O./N.C. programmable PNP outputs or 4 to 20 mA analog output with single PNP output 
  • 316K stainless steel probe
  • Selectable units of measurement: °C, °F, or %

Solid-State 840E Level Sensor

Allen-Bradley 840E level switches are microprocessor based and designed to withstand harsh industrial conditions and wash-down applications such as liquid level monitoring in tanks, containers, and pipelines. Available in both AC and DC versions, these switches are not affected by foam and are immune to vibration and build-up. 

  • Rugged, corrosion-resistant 316L stainless steel housing with IP66/67 rating for DC type and IP65 for AC type enclosure 
  • DC PNP version with M12 connector 
  • AC version with NPT 1/2" valve connector 
  • 316L stainless steel sensing environment 
  • On-site control via high-visibility status LED 
  • Discrete NO/NC level switch is based on ultrasonic vibrating fork technology 
  • Easy to install
