Description

The DSN260 Ammonia Nitrogen Sensor utilizes an ion-selective electrode (ISE) principle to detect ammonium ions (NH₄⁺) in aqueous solutions. Its integrated signal conditioning circuitry provides a stable analog signal that is converted to a digital output via its onboard RS485 Modbus RTU interface, ensuring noise-resistant data transmission over long distances in industrial settings.

Engineered for harsh environmental conditions, the sensor’s robust POM body offers excellent chemical and corrosion resistance. The built-in compensation algorithms for temperature and pH variations minimize measurement drift, delivering accurate and reliable NH₄-N concentration data critical for process control and regulatory compliance in dynamic water systems.

Frequently Asked Questions

What is the communication protocol of the DSN260 Ammonia Sensor?

The DSN260 sensor uses an RS485 serial interface with the Modbus RTU protocol. This standard industrial communication allows for easy daisy-chaining of multiple sensors and direct integration with Programmable Logic Controllers (PLCs), SCADA systems, and data acquisition units that support Modbus.

Does this sensor require calibration or maintenance?

As an ion-selective electrode (ISE) sensor, periodic calibration using standard solutions is recommended to maintain optimal accuracy. The robust POM housing and low-maintenance electrode design minimize upkeep, but the sensing membrane may require cleaning and eventual replacement depending on the fouling conditions of the application.

What power supply voltage does the DSN260 sensor require?

The product description specifies it is 'Electrode-based,' indicating the sensor module includes its own signal conditioning circuitry. Typically, such RS485 Modbus sensors operate on a standard industrial DC voltage range, such as 9-24V DC, which powers both the sensing electronics and the communication interface. Please consult the specific datasheet for exact requirements.

Can this sensor compensate for changes in water temperature and pH?

Yes, the DSN260 features built-in temperature and pH compensation. This integrated functionality automatically adjusts the ammonia nitrogen reading to account for variations in these parameters, which are known to affect ion-selective electrode measurements, ensuring stable and accurate results across different water conditions.
