AMETEK pressure transmitter Model SPT
| Description The Model SPT general purpose industrial pressure transducer is designed for use in a variety of industries. Providing excellent media compatibility with all 316 stainless steel wetted parts, it is perfectly suited for applications where media compatibility is a problem. With its superb stability, low cost and proven reliability, it is ideal for OEM applications. This model provides a high level voltage output from an unregulated supply. Each unit is shipped fully compensated for pressure and temperature and is completely interchangeable without the need for further calibrations. The SPT features a solid state silicon piezoresistive sensing element, electrostatically bonded to glass to virtually eliminate the effects of induced stress and vibration. Behind every SPT series transducer is over 15 years of stainless steel/oil isolation technology. The silicon sensor is completely isolated via an oil- filled chamber. The transducer has a computer-controlled laser trimmed custom hybrid circuit which standardizes output and provides precise temperature and pressure compensation. Rugged construction and a standard Packard electrical connector make it truly cost effective. |
