HD 9408T BARO, HD 9408TR BARO and HD 9908T BARO are analog output electronic barometers. They use a piezoresistive sensor element which gives extremely accurate and stable measurement of the atmospheric pressure and assures excellent repeatability, low hysteresis and very good temperature stability.
- HD 9408T BARO requires a continuos dc power supply, its low power consumption makes it ideal for portable and remote battery or solar powered applications
- It is available in different kinds of analog output: 0-1 Vdc, 0-5 Vdc (1-5 Vdc, 1-6 Vdc on request) or 4-20 mA (two wires)
The output signal of the sensor is conditioned to provide a voltage or a current output linearly proportional to the barometric pressure.
The transmitters are ready as they have been calibrated at the factory. A zero adjustments potentiometer is available for offset to station elevation.
HD 9408T BARO, HD 9408TR BARO and HD 9908T BARO are low cost and excellent performance solutions for meteorological applications, environmental monitoring systems, metrological and environmental data logging, altitude applications, barometric pressure compensation in the performance of internal combustion engine, cleanroom barometric pressure compensation, testing of vehicle emissions.
