Product Description
A defining attribute of the Rosemount 1066 is its HART 7.0 communication protocol integration, the latest version of the globally adopted industrial communication standard. This enables bidirectional data exchange between the analyzer and control systems (DCS/PLC), supporting remote configuration, parameter adjustment, and diagnostic monitoring-eliminating the need for on-site manual intervention in hard-to-reach or hazardous locations. Complemented by automatic temperature compensation (ATC), the analyzer adjusts measurements in real time to account for temperature fluctuations, a critical factor that impacts the accuracy of water quality parameters. This ensures consistent performance even in environments where temperature varies widely, from cold municipal water supplies to high-temperature industrial process streams.
- Principle: The analyzer uses a glass electrode (for pH) or noble metal electrode (for ORP) to detect hydrogen ion activity in water. For pH, the glass electrode generates a voltage proportional to the pH value (per the Nernst equation), while the reference electrode provides a stable reference potential. For ORP, the noble metal electrode (typically platinum or gold) measures the electron transfer potential between the electrode and the water sample, indicating the oxidizing or reducing nature of the solution.
- Temperature Compensation: Integrated automatic temperature compensation adjusts the electrode signal based on real-time temperature data (collected via a built-in RTD sensor). This compensates for the temperature dependence of electrode response-critical for maintaining accuracy, as pH measurements can shift by ~0.03 pH units per °C without compensation.
- Advantage: The electrodes feature a double-junction reference design that minimizes contamination and drift, extending service life and reducing calibration frequency. The analyzer also supports automatic calibration with two or three standard buffers, ensuring traceability to NIST standards.
Features
- Principle: Conductivity is measured using a four-electrode cell design, which eliminates polarization effects common in two-electrode systems. An alternating current (AC) is applied across the outer electrodes, while the inner electrodes measure the voltage drop-proportional to the water's conductivity (ability to conduct electric current, determined by dissolved ions).
- Range Adaptability: The analyzer automatically adjusts its measurement range (from 0.01 µS/cm to 2 S/cm) to match the sample's conductivity, ensuring accuracy across both ultra-pure water (e.g., boiler feedwater) and high-salinity water (e.g., wastewater, seawater).
- Temperature Compensation: Conductivity is highly temperature-dependent (typically increasing by 2-3% per °C for most electrolytes). The Rosemount 1066 uses a temperature coefficient (adjustable from 0.0 to 5.0%/°C) to compensate for this effect, referencing measurements to a standard temperature (25 °C) for consistency.
Industrial Process Control
- Principle: The analyzer employs a polarographic or optical DO sensor. Polarographic sensors use a cathode and anode in an electrolyte solution, with oxygen diffusing through a membrane and undergoing reduction at the cathode-generating a current proportional to DO concentration. Optical sensors (optional) use luminescence quenching: a light-emitting diode (LED) excites a luminescent layer on the sensor tip, and oxygen molecules quench the luminescence in proportion to their concentration, with the sensor measuring the decay time.
- Temperature and Pressure Compensation: DO solubility decreases with increasing temperature and pressure. The Rosemount 1066 automatically compensates for both, using built-in temperature and pressure sensors (or external pressure inputs) to adjust measurements to standard conditions (1 atm, 25 °C), ensuring accuracy in applications like boiler water or deep-water monitoring.
- Advantage: Optical DO sensors offer longer service life (no electrolyte replacement) and faster response times, while polarographic sensors provide cost-effective reliability for standard applications. Both options are resistant to fouling and interference from chemicals like hydrogen sulfide.
- Principle: Turbidity (cloudiness caused by suspended particles) is measured using the nephelometric method, which detects light scattered by particles at a 90° angle to the incident light source. A tungsten-halogen or LED light source illuminates the sample, and a photodetector measures the scattered light-with the signal proportional to turbidity (in NTU, Nephelometric Turbidity Units).
- Calibration and Stability: The analyzer supports calibration with standard turbidity solutions (e.g., Formazin) and features a self-cleaning option (ultrasonic or wiper) to prevent particle buildup on the sensor window, maintaining measurement accuracy in high-turbidity environments like wastewater treatment.
