Rochester Gauge 5632S02539P Jr. Size TwinSite 240-30 Ohm Dial Face - Industrial Pressure Measurement for HVAC, Automotive & Hydraulic Systems

The 5632S02539P TwinSite is a magnetically-driven, variable-resistance sender with potted lead wires. Senders are utilized on mobile applications where direct reading plus an electrical signal to a remote receiver are required. Models are available to fit all Rochester Junior or Senior, liquid-level gauges equipped with our large Alnico drive magnet. This 2-wire TwinSite sender employs a laser trimmed, heavy duty resistance element. The TwinSite is capable of generating accurate and reliable signals to remote receivers in most common resistance ranges The standard model of this Twin¬Site comes with the premium harsh environment construction at the price of the previous standard unit. 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.
