Proximity Transducer system

This system has three individual parts

PROBE

This part is installed on the machine. It has a tip assembly, made of a generic version of polyphenylene sulfide (PPS), that threads into a stainless steel case. The tip assembly is 8mm in diameter and contains a coil whose ends terminate to a 75 ohm miniature triaxial cable that exits the stainless steel casing. The triaxial cable has one center conductor, as a coil connection, and two screens. The inner screen is a coil connection and the outer screen is not connected. This prevents unwanted grounding of one side of the coil if the cable is damaged.

The cable terminates to a 75 ohm miniature coaxial male connector.

EXTENSION CABLE

This is the part that connects to the probe and allows you to reach a convenient junction box. It has a length of triaxial cable identical to that used on the probe. One end of the cable terminates to a 75 ohm miniature coaxial female connector for connection to the probe. The other end terminates to a 75 ohm miniature coaxial male connector for connection to the Proximitor.

A piece of heat shrink is available on the cable to be slid over the probe to extension cable extension cable connection. This prevents unwanted grounding of one side of the coil.

PROXIMITOR

This is the part that contains the electronics and is usually mounted in a junction box. It has a die cast aluminum case with a powder gray coat that resists oils, solvents and chemicals. A 75 ohm miniature coaxial female connector is chassis mounted through the casing for connection to the extension cable. A terminal strip is also case mounted for supplying voltage to and taking signals from the Proximitor. The base has an isolation plate mounted on it that will prevent unwanted grounding of one side of the probe coil. The circuit board mounted electronics are fully encapsulated in resin within the casing. A calibration resistor mounts under the nameplate that must only be changed according to the operation manual.

The proximitor dictates which probe and extension cable lengths Matches the system
