The sensor is made of PEEK, fits into the same space, and has similar specs. The electrodeless sensor measures accurately over a wide dynamic range and can be used in applications from 50m S to 1,000 msec. The sensor design resists fouling, providing longer unattended service. It also uses noncontacting toroidal technology that eliminates contamination and calibration issues. The sensor is immune to thin coatings that impair direct contacting sensors.
