SAT210 Spectrophotometric Absorbance Transmitter

• Dye, color and concentration control in textile, water treatment and chemical industries

• Monitoring the completeness of the rinsing processes

• Leak detection of heat exchangers or condensers

• Phase separation of product/water and liquid/liquid mixtures

Overview

SAT210, measures light absorbance in the visible range for 6 different wavelengths to monitor the concentration changes based on Beer-Lambert law. For each path length, a pair of LED and photodetector is utilized. Measuring the actual temperature by integrated temperature sensors, SAT210 compensates the drift in the photodetector readings due to temperature changes. Due to additional feedback detectors, the aging of the LEDs is also compensated. Fluorinated ethylene propylene (FEP) body ensures protection against aggresive chemicals and up to 140 °C process temperature.

• Two path lengths available: 1 mm, 10 mm
• Absorbance range: 0 … 3 AU (absorption units)
• Absorbance values for 6 different wavelengths (450, 500, 550, 570, 600 and 650 nm) along with total absorbance in the visible spectrum
• Simple automatic calibration procedure • Reference feedback detectors to compensate for LED aging
• Very high chemical resistant FEP body, durable to 140 °C
• Configuration and operation via − Bluetooth and EliarSmart App − Wi-Fi and embedded web server
• Dual 4-20 mA analog current output channels, selectable for any wavelength

SAT210 is designed to be used in the following applications & industries:

• Dye, color and concentration control in textile, water treatment and chemical industries
