PRYDE Measurement has introduced the new Setra Model 278 barometric pressure transducer that is ideal for Automated Weather Systems (Aws) applications.
It features low power consumption, while its instant warm-up feature makes it suitable for environmental applications where pressure readings must be taken quickly.
In addition, the transducer's compact size (92mm x 61mm x 25mm), 1/8" barbed fitting for push on tubing and a 5 pin terminal strip for connection makes it easy to install and convenient to use.
Using Setra's long proven Setraceram variable-capacitance sensor, which is a symmetrical ceramic capsule that deforms proportionally to applied pressure and patented electronic circuitry, the Model 278 barometric pressure transducer provides excellent thermal expansion co-efficient and low mechanical hysteresis, which contributes significantly to its long-term stability.
Designed to be environmentally rugged, it has full temperature compensation over the range of -40°C to +60°C and ±0.5hPa/mb accuracy.
Offered in absolute pressure ranges from 500 to 1100hPa/mb, 600 to 1100 hPa/mb and 800 to 1100hPa/mb, the transducer provides long term stability of 0.1hPa/mb full scale per year.
Outputs of either a 2.5Vdc or 5Vdc are available with 9.5Vdc to 28Vdc excitation.
