Description

This sensor measures the electrical conductivity (EC) of aqueous solutions, a key parameter for assessing water quality, salinity, and dissolved solids concentration. It operates on the principle of applying an AC excitation voltage to two electrodes within the probe, measuring the resulting current to calculate solution conductivity. The integrated PT1000 sensor provides precise temperature data essential for accurate EC compensation, as conductivity is highly temperature-dependent.

Designed for demanding environments, the probe features a robust, IP68-rated housing capable of withstanding continuous submersion and pressures up to 0.5 MPa. The onboard signal conditioning circuitry provides a clean, filtered 0-3V analog output, minimizing noise for reliable data acquisition by microcontrollers or data loggers. Its operating temperature range of 0 to 100°C makes it suitable for a wide variety of hot process or environmental monitoring applications.

Key Features

  • Industrial-grade IP68 waterproof construction for reliable long-term submersion.
  • Hardware-filtered 0-3V analog output ensures stable, low-noise signal acquisition.
  • Integrated high-precision PT1000 platinum RTD for automatic temperature compensation.
  • Wide operating range from 1 to 2200 µS/cm with a standard cell constant (K=1).
  • Robust probe design rated for pressures up to 0.5 MPa and temperatures from 0 to 100°C.
  • Plug-and-play Gravity interface simplifies wiring and connection to compatible controllers.
  • Optimized performance-to-cost ratio for professional water quality monitoring systems.

Applications

  • Continuous conductivity monitoring in hydroponic nutrient solution tanks.
  • Salinity and total dissolved solids (TDS) measurement in aquaculture and aquaponics systems.
  • Environmental water quality assessment in rivers, lakes, and wastewater treatment plants.
  • Process control and quality monitoring in industrial water treatment and boiler systems.
  • Laboratory-grade water purity testing and research applications.

Frequently Asked Questions

What is the operating voltage range for this EC sensor?

The sensor operates from a 3.3V to 5.0V DC power supply. This range makes it directly compatible with most microcontroller boards like Arduino (5V) and Raspberry Pi or ESP32 (3.3V) without requiring a level shifter. Ensure your power source is stable to maintain measurement accuracy.

How do I connect and read data from the sensor?

The sensor uses DFRobot's Gravity 3-pin connector (Signal, VCC, GND). Connect it to a microcontroller's analog input pin. The output is a 0-3V analog voltage proportional to conductivity. You will need to apply a temperature compensation algorithm using the integrated PT1000 readings, typically via a library provided by DFRobot.

What does the IP68 rating mean for the probe?

IP68 signifies the probe is dust-tight (6) and protected against continuous immersion in water under specified pressure (8). This probe is rated for submersion at depths generating up to 0.5 MPa of pressure, making it suitable for permanent installation in tanks, pipes, or natural water bodies.

Do I need to calibrate the sensor, and what is the cell constant K=1?

Yes, calibration using standard conductivity solutions is recommended for accurate measurements. The cell constant (K=1) is a geometric factor relating the probe's electrode area and spacing to the measured conductivity. A K=1 probe is a standard design suitable for the 1-2200 µS/cm range, and calibration factors are applied in software.

Can this sensor be used in high-temperature liquids?

Yes, the probe is rated for an operating temperature range of 0 to 100°C. The integrated PT1000 temperature sensor is crucial for compensating the conductivity reading, which varies with temperature. Ensure all connections and the cable gland are properly sealed before exposing the probe to high-temperature or high-pressure environments.
