TSW-20M Turbidity Sensor Module-Wal Front Accurate for Sewage Washing

Description

Product Overview

The TSW-20M Turbidity Sensor Module is engineered to provide precise measurement of water clarity in a variety of industrial and domestic environments. Built by Wal Front, the module utilizes an optical detection principle where a light source and photodetector are positioned opposite each other within the sensor housing. When particles are present in the liquid, they scatter the light, causing a measurable change in the received signal. This change is then converted from sensor current to a proportional output voltage, allowing easy integration with standard control systems.

Compact dimensions of 0.39 x 0.39 x 0.39 inches and a lightweight design of 0.71 ounces make the TSW-20M suitable for installation in tight spaces, such as inside washing machine cabinets or compact wastewater monitoring stations. The module operates on a low power supply and features a simple three‑wire connection—power, ground, and signal—reducing wiring complexity and installation time.

Designed for durability, the sensor housing is constructed from robust polymer material that resists corrosion and chemical exposure commonly encountered in sewage and industrial water streams. The optical components are sealed to protect against dust and moisture, ensuring long‑term stability and consistent performance over thousands of operating hours.

Performance specifications include a detection range from clear water up to highly turbid solutions, with a linear response that enables accurate calibration against standard turbidity units. The module’s output voltage decreases as turbidity increases, providing an intuitive inverse relationship that simplifies interpretation in control algorithms.

Compatibility with a wide range of microcontrollers, PLCs, and data acquisition systems makes the TSW-20M a versatile choice for engineers seeking a reliable sensor that can be seamlessly incorporated into existing monitoring infrastructure. Whether used for real‑time feedback in washing machine cycles or continuous monitoring of municipal wastewater treatment processes, the module delivers consistent data that supports informed decision‑making.

Usage

In residential washing machines, the TSW-20M sensor can be placed in the water inlet line to continuously assess water clarity before each wash cycle. By detecting high turbidity levels, the controller can adjust water usage, add extra rinse steps, or trigger maintenance alerts, thereby improving cleaning efficiency and extending appliance lifespan.

Industrial applications include monitoring of cooling tower water, where turbidity can indicate scaling or biological growth. The sensor’s rapid response enables automatic dosing of treatment chemicals, maintaining optimal water quality and preventing costly equipment downtime.

Municipal wastewater treatment facilities benefit from the module’s ability to track influent turbidity, allowing operators to fine‑tune sedimentation and filtration stages. Accurate turbidity data supports compliance with environmental regulations and helps reduce the discharge of suspended solids into natural water bodies.

Laboratory settings can also leverage the TSW-20M for experimental measurements of water samples, providing a cost‑effective alternative to larger bench‑top turbidity meters while maintaining high accuracy and repeatability.

FAQ

What is the measurement range of the TSW-20M sensor?

The sensor can accurately detect turbidity from clear water (near 0 NTU) up to highly turbid solutions exceeding 1000 NTU, making it suitable for both low‑level monitoring and high‑load industrial applications.

How is the sensor calibrated?

Calibration is performed using standard turbidity solutions with known NTU values. The module’s output voltage is recorded for each standard, and a calibration curve is generated in the host controller to translate voltage readings into turbidity units.

Can the sensor be used with a microcontroller?

Yes, the three‑wire interface (VCC, GND, SIGNAL) is compatible with most microcontrollers and development boards. Sample code and wiring examples are provided in the product documentation.

Is the sensor suitable for continuous operation?

Designed for 24/7 operation, the TSW-20M features a sealed optical chamber and low power consumption, allowing it to run continuously without degradation of accuracy.

What warranty does Wal Front offer?

Wal Front provides a one‑year limited warranty covering manufacturing defects, along with access to replacement parts and technical assistance throughout the warranty period.
