Advanced Matrix Film TwinSite™ For Industrial Applications General Information & Features This 2-wire TwinSite™ sender employs a laser trimmed, advanced matrix resistance element. The TwinSite™ is capable of generating accurate and reliable signals to remote receivers in most common resistance ranges with infinite resolution (see the back side for the technical specifications). The standard model of this TwinSite™ comes with the premium harsh environment construction at the price of the previous standard unit. The dedicated ground path terminal wire eliminates the major reliability fault found in most variable resistance sender designs. Redundant wiper and collector contacts are used to improve reliability and reduce contact noise. In testing, this unit has geatly surpassed the competitive units in reliability and durability. The Twinsite™ also provides the easiest to read local indication of any Twinsite™ sender Rochester has produced. The bright, user friendly dial face is divided into fractional units. The case is hermetically sealed by ultrasonic heating to melt and fuse the case into one solid piece. This keeps weather out, ensuring ‘’no-fog’’ readability while greatly extending mechanical life. The seal is a high reliability, no-gasket design. The plastic case is capable of withstanding vibration and shock that would render comparable metal designs useless. The plastic case is far more resistant to corrosion than any metal-cased version and is capable of withstanding broad variations in temperature. The plastic lens (and the rest of the case) is a special, UV stabilized material. Electrical connections are sealed with multiple epoxy chambers. The connecting wires are also sealed behind this epoxy barrier. This sealing process prevents sparks or other damage due to both galvanic and electrolytic corrosion, as well as, providing an impervious barrier to road salt. The sender is mounted onto the Rochester Junior™ gauge with #0040-00416 stainless steel dial screws (6-32 X 5/16”). An additional item available to ensure weatherproof connections from the Twinsite™ to the receiver is heat shrink solder sleeves part number 0025-00495.
