The FirstRate ST100-ZD102 turbidity sensor employs a nephelometric optical sensing principle, where a light source illuminates suspended particles in a liquid and a photodetector measures the scattered light intensity. This method provides reliable and repeatable turbidity readings critical for process control and water quality compliance. The sensor’s signal conditioning electronics deliver stable, low-noise outputs suitable for long-distance transmission in industrial settings.
Encased in corrosion-resistant 316 stainless steel and rated IP68, the sensor is built to withstand continuous immersion, high-pressure washdowns, and chemically aggressive environments. Its wide 9-30 VDC input voltage range, with 12 VDC recommended, ensures compatibility with standard industrial power supplies, making it a versatile solution for monitoring clarifiers, filter effluents, and raw water intakes.
