Abstract
A conductivity probe having a modular design. A probe body has a distal end and a proximal end. The distal end includes a recessed portion for providing a seat for an O-ring that seals an electrode tip assembly. The probe body also includes a set of internal threads for engaging with cooperating threads disposed on the electrode tip assembly. The distal end of the body terminates in a bottom wall having an opening leading to a connection pipe attached to a junction box. The exterior of the probe body includes a stepped down profile of varying constant diameters with a side port formed in the probe body for receiving a temperature compensation probe. The probe body includes a set of external threads and wrench flats for installing the probe into a boiler conduit. The design is completely modular with minimal assembly required. The probe body is machined easily and features hard stops for trouble-free assembly. Also, there is no potting of the electrical components required.
