Digital Smart SENCOM® pH/ORP Sensor FU24F

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.

• Solid Platinum ORP/LE electrode for accurate simultaneous pH and ORP measurements

• Integral Pt1000 element for enhanced pH accuracy

• Extended life time by saturated Ag/AgCl reference system with double junction combined with ion-trap, and porous PTFE reference diaphragm

• Easy setup by sensor specific characteristics stored in the sensor itself

• Simple maintenance by comprehensive design

• Available in two versions, a robust dome shape model for applications with a limited amount of solids, and a flat surface model for applications in which solids are a considerable component

• IP67 M9 Cable Connection

• CE, ATEX, CSA and FM Approval. However *Can only be used General Purpose at this time, because FLXA21 SENCOM® module and SPS24 Interface box are pending ICECx, ATEX, FM and CSA approval*

WU11 Connection Cable

The WU11 interconnection cable is specified for reliable transfer of digital signals between the SENCOM® sensors and Yokogawa FLXA analyzer. It is espically designed to be installed in a heavy industrial environment. The cable is water proof, IP67, allowing it to be submerged as a whole. The cable has a wide temperature operation range which is sufficient for most of the applications. The materials used for the cable are flame retardant to resist the spread of fire.

• Double shielding to protect connected devices for interference from high voltages and currents

• Available in four different lengths. Long cable runs up to 100 m (328 ft) are possible

• Easy connection to a SENCOM pH Sensor by one 5- pins molded connector, and to the analyzer by 5 wired pins

• Flame retardant recognized by UL (fileno. E124763) and CSA (fileno. LL105324)

• IP67

• Operating temperature from - 40ºC up to + 85°C (-40ºF up to +185°F)
