Differential pH Sensor Model PH18
GS 12B6J4-01E-A The Model PH18 Differential pH Sensor is unique and offers the possibility of maintenance-free operation for the correct application. Construction of the enamel coated probe is based on a rigid steel rod. A blue base enamel is overlaid with two yellow bands of sensitive enamel. One pH sensitive enamel and the second a sodium ion enamel. They are combined with an integral temperature sensor, to form a probe that does not have any internal solutions. The differential measuring principle combines the normal potential generated by the pH enamel with the potential from the sodium membrane. In suitable applications the level of sodium ions creates a stable reference voltage. Hence the measurement can be made without a conventional reference electrode, and drawbacks associated with a liquid junction. The sensitive enamels are directly bonded to a metallic substrate, eliminates the need for conventional internal reference elements. This unique construction makes the PH18 independent of the drift typically caused by conventional reference elements as they age or become contaminated. When used in a system which is cleaned and/or sterilized with hot water or steam, the enamels produce a signal which has long term stability unrivalled by conventional systems.

Screw or weld-in adapter mounted on top of a large bore pipe.
Fig. 14. The primary adapter is used to make a connection to the process used by the transmitter as the liquid earth (solution ground). This is needed for optimum stability of the measurement and is also used in the impedance checking circuit.
Note 1: When measuring in plastic tanks or pipes, ensure that the adapter is wetted by the process. Avoid installations where an air pocket can be created (see fig 12 F). This isolates the adapter, and hence loses the liquid earth connection. Note 2: Flow rate from the side of sensor (fig. 12 (C & D) ) should not exceed 2 metres/second in low viscosity fluids. In high viscosity fluids (>5cP) use only installation as shown in fig. 12 (D).
Fig. 15. Should be used to show process variations. The changes in pH and sodium content should be plotted against time for batch processes. Changes in temperature and pressure can also be plotted if appropriate. Where CIP is used, plot the cleaning cycle, and any sterilization stages. This leads to a clearer understanding of the process.

SPARE PARTS PH18-SA Caution - Inappropriate handling can cause damage. Striking or scratching the sensor against hard surfaces such as steel, stone, glass or ceramic, may cause damage to the enamel. Such damage may not affect the sensor performance immediately, but after prolonged exposure to the process, flaking of the enamel may occur.
Note - Enable impedance checks in the PH202 or PH402 The sensor impedance checking can give early warning of damage to the enamel layers. If the transmitter signals an impedance failure of the PH18, the sensor should be removed from the process, as soon as possible (within 24 hours). The loss of significant amounts of enamel may thus be avoided.
