pH sensor

The FU24F is a an all-in-one digital smart pH and ORP sensor made with a chemical resistant PPS 40GF body for harsh pH applications. It is particularly useful in harsh applications with fluctuating pressure and/or temperature. These processes shorten sensor life because the process fluids move in and out of the sensor under influence of frequent pressure and/or temperature fluctuations. This results in fast desalting and dilution of the reference electrolyte which in turn changes the reference voltage causing a drifting pH measurement.

By integrating the successful Yokogawa patented Bellow design concept within the FU24F electrode, a strong pressure compensation mechanism is created. The built-in bellow ensures immediate interior pressure equalization to the outside pressure, making the sensor virtually insensitive to external pressure variations. A slight overpressure caused by the bellow tension, prevents fluid ingress and maintains a positive ion flow out of the sensor.
