Frequently Asked Questions

What is the power supply requirement for the DS285 TDS sensor?

The DS285 operates from a 6-12V DC power supply with a current draw of less than 50 mA. Ensure your power source is stable and within this range for proper sensor function and to avoid damage.

How do I communicate with this sensor and what protocol does it use?

The sensor communicates via an RS485 digital interface using the Modbus RTU protocol. You will need an RS485-to-USB converter or an RS485 port on your PLC/controller to read the TDS and temperature data. Refer to the manufacturer's datasheet for the specific Modbus register map.

Is this sensor suitable for continuous submersion in water?

Yes, the DS285 features an IP68 waterproof rating, meaning it is protected against continuous immersion in water under the specified pressure and temperature conditions. Its SS316 + PPEK housing provides excellent corrosion resistance for harsh aqueous environments.

Does the sensor require calibration, and how is temperature compensation handled?

The sensor is pre-calibrated, but field calibration may be recommended for critical applications using standard solutions. It has a built-in temperature sensor that automatically compensates the TDS reading in real-time, ensuring accuracy across the 0-50°C operating range.

What is the maximum cable length for reliable data transmission?

The sensor includes a 5-meter integrated cable. For RS485 communication, you can extend the network significantly (up to 1200 meters typically) by using proper shielded twisted-pair cable and termination, adhering to RS485 standards for noise immunity.
