These probes consist of an electrode and an impedance converter inside a two-part housing held together by a threaded collar. There is extra sealing so that the connections at the top of the electrode remain dry even when the probe is completely submersed.
These probes consist of an electrode and an impedance converter inside a two-part housing held together by a threaded collar. There is extra sealing so that the connections at the top of the electrode remain dry even when the probe is completely submersed.
The impedance converter immediately over the electrode eliminates electrical noise problems and permits the use of ordinary cable to connect the probe. Either light duty or heavy duty pH or redox electrodes with flange fittings can be used.
As standard probes are manufactured from PVC (for temperatures up to 60°C), but on request they can be supplied in other materials, e.g. PP for up to 10 bar at 25 °C, 4 bar at 90 °C, or PVDF for up to 6 bar up to 100°C, 2 bar at 120°C.
There are three basic designs, one for free mounting, one with a 3/4″ tee for flow-through use, the third designed to be screwed into a pipe, flange or other suitable fixture. The probes can be ordered with a 1″ thread at the top of the top part for mounting purposes.
For Heavy Duty use in very dirty environments probes can be supplied with a probe cleaning system. This has, for example, proved effective when measuring agricultural slurry. Several types of mounting device are also available.
