MP part of the model number mean A MICROPROCESSOR BASED ELECTRONICS As opposed to analog circuitry The MP units measure temperature as well as pressure This allows the output to be kept within tolerance over a 0 50 C range The MP boards are capable of digital communication with other devices Communication options must be selected when ordering Q How do mount it A There are several options available depending on the model These are the most common Most of our sensors are installed by hanging the unit by its cable Often a strain relief is used so that the cable is not crimped at the hanging point It is not uncommon to hang a sensor 500 feet down a well with no additional support other than the cable SB Option The cable support bracket is attached to the sensor Stainless steel cable is attached to the bracket and run along side of the submersible cable This allows the sensor to be pulled up by the stainless steel cable This prevents the sensor from being separated from the cable when being removed from an installation where the sensor may be restricted SB options must be selected when ordering CD Option The conduit adapter allows the sensor cable to be run inside conduit while rigidly holding the sensor in place 77 conduit with a male threaded end or fitting is screwed into the top of the sensor The conduit can be mounted using standard electrical hardware CD options must be selected when ordering SO
