FAQs
What communication protocol and output does the ADP2400 pH sensor support?
The ADP2400 features a standard RS485 digital interface supporting the Modbus RTU protocol. It enables reliable, long-distance data transmission and can directly integrate with PLCs, DCS, SCADA systems, and IoT environmental monitoring platforms without requiring a secondary transmitter.
What applications is this digital pH electrode designed for?
It is specially engineered for data center liquid cooling circuits, HVAC circulating cooling water, and industrial water treatment systems. It provides continuous in-line monitoring to prevent acid/alkaline corrosion and scaling in pipelines and heat exchangers.
How is the sensor calibrated and does it support temperature compensation?
Yes. The electrode supports fast 2-point or 3-point calibration and features automatic/manual temperature compensation across a wide range of -10°C to 130°C, ensuring high measurement precision of ±0.02 pH throughout its operational lifecycle.
What process connections and pressure ratings does the sensor have?
The sensor adopts an in-line insertion design with either G3/4" thread or 50.5mm tri-clamp connections. Constructed with a robust 304 stainless steel body, it withstands operating pressures up to 1.0 MPa and carries an IP65 protection rating.
What is the operating voltage and cable wiring configuration?
The sensor operates on a wide DC supply of 6-30V (standard 12V DC). The direct-lead cable wiring is: Red (Power VCC), Black (GND), Green (RS485 A), and White (RS485 B).
