Basingstoke, UK: A drop-in replacement for older type electromechanical synchro transducers (transmitters) is available from Kulite Sensors. The APTE-4-2250 series is a synchro type IS® pressure transducer featuring the company’s patented Silicon on Insulator (SOI) piezoresistive sensors and custom electronics, offering significant improvements over electromechanical devices but retaining equivalent fit, form and function. Benefiting from no moving parts, no friction or position errors and better accuracy and stability than its mechanical counterparts, the APTE-4-2250 series transducer is also more cost-effective. Being able to withstand high vibration and shock levels, the device offers high reliability and high MTBF. It is acceleration and vibration insensitive, hermetically sealed and EMI protected. Flight certified and already used on DC-9 and MD-80 series aircrafts, the synchro type transducer is designed for a pressure range from 2 up to 10000 PSI and an operating temperature range from -55 up to +95 °C. It can be used at any altitude and up to 100 % humidity. Proof pressure is twice full scale pressure and burst pressure is three times full scale pressure. Kulite Sensors Ltd, Basingstoke, UK.
