Description
Product Overview
The iDili RS485 Turbidity Sensor Probe is engineered for high‑precision measurement of suspended solids in a wide range of liquid media. Constructed with an anodized aluminum oxide (Al₂O₃) shell, the probe offers exceptional corrosion resistance, chemical inertness, and a smooth surface that prevents bio‑film buildup, thereby maintaining consistent optical performance over extended service periods. The integrated infrared optical detection system utilizes a modulated light source and detector pair to minimize the impact of ambient lighting, while the built‑in temperature compensation algorithm automatically adjusts the signal to account for temperature fluctuations, delivering stable readings from 0 °C to 80 °C.
Designed for RS485 serial communication, the sensor provides robust, noise‑immune data transmission over long cable runs, making it suitable for distributed monitoring networks in industrial plants, wastewater treatment facilities, and remote field stations. The probe supports a wide measurement range of 0–4000 NTU, with a resolution of 0.1 NTU, enabling detection of both low‑turbidity drinking‑water standards and high‑turbidity process streams. Power consumption is low, and the device operates without the need for external batteries, simplifying installation and reducing maintenance costs.
Key specifications include a 4‑20 mA output compatible with standard PLCs, a configurable alarm threshold, and a compact form factor (diameter 30 mm, length 150 mm) that fits easily into existing piping or sampling ports. The probe’s fully sealed design meets IP68 standards, guaranteeing protection against dust ingress and continuous submersion in water up to 5 m depth. All components are RoHS compliant, and the unit carries CE certification for safety and electromagnetic compatibility.
Usage
The iDili RS485 Turbidity Sensor Probe is versatile enough to serve in diverse environments where water quality monitoring is critical. In municipal water treatment plants, the probe can be installed at intake, filtration, and discharge points to continuously verify that turbidity levels meet regulatory standards, helping operators adjust coagulant dosing in real time. In wastewater and sewage applications, the sensor’s robust housing and anti‑interference optics allow accurate detection of suspended solids despite the presence of color, foam, and chemical contaminants, supporting process optimization and compliance reporting.
Laboratory technicians benefit from the probe’s rapid response time (under 2 seconds) and easy integration with data‑logging software via the RS485 interface, enabling high‑throughput sample analysis for research, quality control, and product development. Aquaculture facilities can deploy the sensor in fish ponds and recirculating aquaculture systems to monitor water clarity, which directly influences fish health and growth rates. The probe is also suitable for food‑processing lines, where monitoring of wash water turbidity ensures compliance with hygiene standards and helps detect equipment fouling.
Installation is straightforward: the probe can be mounted using a standard 1/2‑inch NPT thread, and the RS485 cable can be connected to a PLC, SCADA system, or dedicated handheld reader. The device’s self‑diagnostic features alert users to sensor fouling or communication errors, reducing downtime and supporting preventive maintenance schedules. Whether deployed in a fixed plant environment or a mobile field kit, the iDili probe delivers reliable, repeatable data that empowers engineers, operators, and scientists to make informed decisions.

FAQ
What is the measurement range of the sensor?
The iDili probe measures turbidity from 0 to 4000 NTU, covering both low‑turbidity drinking‑water applications and high‑turbidity industrial processes.
Can the sensor be used in chemically aggressive environments?
Yes. The anodized alumina housing is chemically inert and rated to withstand exposure to acids, bases, and salts commonly found in wastewater and industrial streams.
How does the temperature compensation work?
The built‑in algorithm continuously monitors the probe’s internal temperature and adjusts the turbidity signal in real time, eliminating temperature‑induced drift without user intervention.
Is the RS485 interface compatible with my existing PLC?
The sensor outputs a standard 4‑20 mA current loop over RS485, which can be easily configured to match the input requirements of most PLCs, SCADA systems, and data loggers.
What maintenance is required to keep the sensor accurate?
Periodic cleaning with a mild detergent and de‑ionized water is recommended to remove any surface deposits. The sensor’s self‑diagnostic alerts will notify you when cleaning is needed, ensuring consistent performance.
