The CTX optical consistency sensors are capable of continuously measuring fibres and particles greater than 0.88 microns such as stock from 0.001% (10ppm) to 3%, condensate contamination, DAF influent and effluent solids, WWTP effluent or fibre losses in sewers among others. The measuring principle is based on the ability of suspended particles to absorb and reflect NIR-light (near infrared) pulsed at 880 nm.
Featuring a 316 stainless steel construction, the robust CTX 20/25 sensors come with sapphire lenses and are also supplied with 1” NPT couplings for mounting. A 20mm gap between the lenses produces a self-cleaning effect due to the increased velocity.
Pre-calibrated for quick and easy start-up, CTX optical consistency sensors have a one-point adjustment performed after installation against a laboratory test.
The BB2 control box has four selectable calibration curves for applications with varying furnishes. Two CTX sensors (or other sensors in the X-series) may be connected to a single BB2 control box, which provides two 4-20mA outputs. The BB2 box is built with the ability to add an interface board that allows connection to a fieldbus.
