Turbidity sensor TTurb

The TTurb is a digital sensor for optical turbidity measurements according to the 90° IR scattered light method. Depending on the sensor it can be used in pure water up to 100 FNU as well as in raw-, waste- and process waters up to 1000 FNU. TTurb is available with a 10 m or a 2 m fixed cable. Reliable concentration measurements by optical methods Pulsed infrared scattered light procedure No mechanically moving parts Digital reading Preprocessing in the sensor increases measurement sensitivity Light Source - LED Detector - Photo diode Measurement principle - Nephelometry Parameter - Turbidity Measurement range - 0...100, 0...400, 0...1000 FNU Detection limit - 0.5 FNU for TTurb 100 2 FNU for TTurb 1000 Measurement wavelength - 860 nm, FWHM 30 nm T100 response time - 6 s Measurement interval - 3 s Housing material - PET / POM / NBR Dimensions (L x Ø) - 170 x 36 mm - ~ 6.7˝ x 1.4˝ Weight - 0.3 kg - ~ 0.7 lbs Interface - Ethernet (TCP/IP) RS-485 (Modbus RTU) Power consumption - typically <0.9 W with network < 1.5 W Power supply - 12...24 VDC (± 10 %) Connector - 8-pin M12-plug Maintenance effort - ≤ 0,5 h/Monat (typisch) Calibration/maintenance interval - 24 Monate System compatibility - Modbus RTU Warranty - 1 Year (EU & US: 2 years) on electronics; All wearing parts are not included in the warranty Max. pressure - 3 bar - ~ 43.5 psig Protection type - IP68 - NEMA 6P Sample temperature - 0...+40 °C ~ +32 °F... +104 °F Sample temperature - 0...+40 °C - ~ +32 °F... +104 °F Ambient temperature - 0...+40 °C - ~ +32 °F... +104 °F Storage temperature - 0...+80 °C - ~ +32 °F... +176 °F
