Product Overview

The TurBiScat Ex PM 40 is an advanced turbidity measuring device designed for high-precision in-line measurement in explosive atmospheres. It features a compact, seal-less design with robust components like Hastelloy and Sapphire, allowing for minimal maintenance and a wide range of process applications. The sensor uses two-angle scattered light measurement and an integrated two-beam measurement system to compensate for colour and window contamination, ensuring reliable data. The device includes integrated measurement display and communication modules, with easy operation possible via WLAN-capable devices.

Key Benefits

• Certified for hazardous areas: Zone 1, Ex db IIC T3/T4/T5/T6 Ga/Gb (temperature class dependent on medium).
• Two-Angle Measurement (90 degrees/25 degrees) for comprehensive turbidity detection with a single sensor head.
• Two-Beam Measurement for automatic compensation of colour and window contamination.
• Seal-less Design and robust materials ensure minimal maintenance and long-term durability.
• Wide Measuring Range of 0 to 4,000 NTU (0 to 1,000 EBC) with high resolution.
• Optional Colour Measurement at 430 nm in the same sensor.

Applications

• Filtration monitoring and control.
• Turbidity measurement in beverages, particularly spirits like Whisky (cold filtration) and Cognac.
