Detailed Description

1.Product overview:

Suspended solids refer to the degree of obstruction caused by suspended particles in water when light passes through. The presence of soil, silt, fine organic matter, microorganisms, and colloidal particles in water can result in turbidity. The light waves emitted by the transmitter on the sensor are absorbed, reflected, and scattered by the measured substances during transmission. A portion of the transmitted light reaches the detector at the 180° direction. The intensity of the light received by the detector is related to the suspended solids value of the wastewater being measured. Therefore, by measuring the intensity of the transmitted light, the suspended solids value of the wastewater can be calculated.

Widely used in the monitoring of suspended solids in solutions in industries such as chemicals, electroplating, papermaking, environmental water treatment, pharmaceuticals, food, and tap water. Especially suitable for use in the field and on-site.

2.Main features:

• The sensor housing is made of 316L stainless steel, offering excellent corrosion resistance.
• The turbidity sensor is unaffected by sample flow rate and pressure.
• The infrared light waves emitted by the transmitter on the sensor use a stable, invisible near-monochromatic infrared light source, avoiding interference from liquid colour and external visible light on sensor measurements.
• The sensor’s optical path uses quartz glass lenses with extremely high light transmittance, ensuring more stable infrared light emission and reception.
• The instrument features a new waterproof, dustproof, and moisture-resistant high-quality housing (IP65) with a painted surface finish, offering a sleek and premium appearance.
• Wide measurement range, stable measurement, high accuracy, good repeatability, and strong anti-interference capability.
• Communication functions: Equipped with an RS-485 communication interface (partially compatible with MODBUS protocol) (optional); optically isolated 4–20 mA current output, with corresponding values that can be arbitrarily set.
• Arbitrary hysteresis setting function to prevent frequent switching of relays, with configurable switch on and off functions.
• Uses a two-point calibration method, allowing the instrument’s measurement range to be modified.
• Watchdog function: Ensures the instrument does not freeze.
• Power failure protection > 10 years.
