Setra Systems, Inc. released their newly enhanced model 470T digital pressure transducer for clean dry air and gases. The Model 470T now features an improved compensated temperature range of -20 to 65°C (-4 to 150 °F) and operating temperature range of -40 to 75°C (-40 to 167°F). These wider temperature ranges make the 470T particularly well suited for weather observation applications, which operate in extreme environmental conditions and experience wide swings in temperature.
The 470T is a versatile microprocessor based instrument which utilizes Setra’s Setraceram (TM) sensor, advanced digital electronic circuitry and sophisticated firmware. All combine to give a system accuracy of better than +0.02% full scale, in pressure ranges from 0 to 10, 20, 50, and 100 psia; 600 to 1100 mbar or 800 to 1100 mbar.
Equipped with a bi-directional RS232C digital communications I/O port for computer access, hi and lo alarm setpoints, zero/tare functions, and min/max value tracking, the 470T has applications in Automatic Weather Observations Systems (AWOS), Barometric Pressure Compensation for Wavelength of Laser Beams, Pressure Transfer Standard, Altimeter Calibration Recertification, Lab or Production Process Monitoring, Altitude chambers, and Weather Data Buoys.
