NOSHOK Series 640 Transducers have been designed for industrial and laboratory applications requiring high accuracy and repeatability with excellent compensation for the effects of temperature. The temperature compensation system practically eliminates temperature induced errors from 50 °F to 104 °F. Series 640 Transducers utilize thin film and diffused semiconductor technology dependent on pressure range. These sensors are highly accurate, shock resistant and extremely stable over long periods of time. Standard output is a digital output with an RS232-C serial interface. Other outputs and electrical connections are available to meet the demands of almost any precision application. A final electrical output and calibration inspection is performed on all NOSHOK Series 640 Transducers prior to shipment to ensure 100% \"out of the box\" reliability.
