ASCO RD20A11 Transducer Air Oil Gas Sensor Module

The ASCO RD20A11 Transducer is a compact pressure transducer unit designed for air, oil, or gas service and intended for use with ASCO’s TRIPOINT pressure-switch configurations. It features a 1/4" NPT process connection, an aluminum housing, and Buna-N sealing for robust operation in industrial pneumatic and fluid-handling environments. Inside is a built-in pressure sensor and a self-contained subassembly that integrates with control circuits to convert sensed pressure into an electrical signal, compatible with 125–250 VAC systems and weighing about 0.47 lb. This RD20A11 component is used to monitor and signal pressure in compact installations across air, oil, or gas lines, providing real-time sensing for automatic control and safety interlocks in HVAC, pneumatic, and process systems.
