PRESSURE TRANSDUCERS A pressure transducer discovers the approximate location(s) of leaks in a cable section. It detects pressure changes on a cable at the point of installation, functioning like a “C” gauge permanently installed on a cable and hooked up to a telephone line. Pressure changes are reported to the maintenance center or central office for analysis, eliminating the need for a technician to make a field trip to determine cable pressure levels. Specification - For all J59 Transducers Pressure range: 0 to 9.5 PSIG or 5 to 14.5 PSIG Maximum pressure: 45 PSI Electrical range: 100,000 to 3,820,000 OHMS in 0.5 PSI steps Accuracy: +/- 0.25 PSIG Field adjustable for elevation: sea level to 10,000 feet Enclosure: Galvanized cast iron Weight: J59F 2 lbs. 4 oz.

UNDERGROUND PRESSURE TRANSDUCERS The J59 underground transducers are the products of over thirty years experience in the design and manufacturing of specialized products for the telephone communication industry. Meeting all specifications of AT-8772 & CA-8772 the J59 transducers are the equivalents of “F”, “G” and “H” transducers, thousands of which are in operation today. Specifically designed for telephone monitoring, and compatible with all existing monitoring equipment, the J59’s offer the following standard versions: J59F The J59F, commonly referred to as the “F” transducer is designed to be mounted on the J59C transducer housing (previous page). It allows pressure in cables to be read remotely over 0-9.5 PSI in 0.5 steps. A sealed external adjustment allows for calibration to local elevation from sea level to 10,000 feet. The galvanized cast iron enclosure is especially suited to underground cable use.
