Smart Sensors

 
ODO8000, Lumin-S Optical Dissolved Oxygen Sensor with Digital Communication
  • The Lumin-S optical dissolved oxygen sensor delivers reliable DO measurements over a long operating life. There are no membranes to replace, no electrolyte solutions to replenish, and no anodes to clean. Maintaining the sensor is as easy as replacing the optical sensing cap once every 1-2 years, and since all calibration data is stored on the cap, there’s no need to calibrate. This dissolved oxygen sensor outputs a Modbus/RS-485 digital signal for easy PLC integration.

  • Reliable measurements: Optical sensor technology delivers accurate DO monitoring with no drift and no minimum flow

  • Long operating life with minimal maintenance: No membranes, electrolyte solutions, or anodes – just replace the cap once every 1-2 years

  • No calibration: All calibration data is stored on the cap for quick and easy startup

  • Simple system integration: Use Modbus/RS-485 to integrate with a PLC or other control system

  • One year limited warranty: We stand behind all our products with the Sensorex Guarantee

S272CD-ORP Online Process ORP Sensor with Digital Communication
  • Moderately contaminated water, such as industrial source water or natural water resources, may contain chemicals and debris that damage ORP probe components. Continuous monitoring in these types of applications requires a durable and low maintenance ORP probe. Our S272 series of ORP probes feature a double junction design to protect the reference cell from contamination by sample components that interact with silver. The flat measurement surface is self-cleaning and resists breakage, for minimal maintenance.

  • Reliable performance in demanding applications

  • Extended sensor lifetime

  • Versatile design for submersion or in-line mounting

  • One year limited warranty

FCL Amperometric Free Chlorine Sensor
  • Chlorine exists in different chemical forms in solution, including free chlorine (hypochlorite ion and hypochlorous acid) and combined chlorine. Free chlorine is the only form that can perform disinfection, so knowing free chlorine concentration is critical for applications like water and wastewater treatment. FCL free chlorine sensors from Sensorex provide a direct measurement of free chlorine in parts per million (ppm). Using field tested amperometric technology, our FCL sensors perform continuous monitoring without any additional reagents. With a direct 4-20mA output, the FCL sensors can be used with any instrument accepting a 4-20mA input or connected directly to a PLC or SCADA.

  • Direct free chlorine measurement in parts per million (ppm)

  • No reagents requried

  • Direct 4-20mA output
