About This Product
■Summary
・Excellent accuracy and stability with temperature-compensated piezo pressure sensor
- Abundant output options: scalable analog current/voltage, output, RS232C, RS422, RS485, SDI-12 digital output
・Wide operating temperature range from -40 to +85℃, accuracy ±0.1hPa
・Modbus-RTU, NMEA0183, SDI-12 standard protocols
The HD9408.3B is a barometric pressure transmitter using a high-precision, temperature-compensated piezo pressure sensor. With extremely high accuracy, stability over time, low hysteresis, and excellent reproducible temperature characteristics, it measures air pressure in the range of 500 to 1200 hPa with analog output and 0 to 1350 hPa with digital output.
The outstanding performance of the HD9408.3B is due to the adoption of a silicon-type piezo pressure sensor that integrates both pressure-sensitive and temperature-sensitive elements. The pressure and temperature measured by the sensors are processed by a microcontroller into output signals that are compensated over an extremely wide operating temperature range of -40 to +85°C.
The sensor is factory calibrated at multiple temperature points throughout its operating temperature range. With its low power consumption design, the HD9408.3B is also a suitable transmitter for remote data acquisition such as solar powered automatic weather stations. Additionally, the waterproof housing with IP67 protection rating allows the transmitter to be used even in harsh environmental conditions.
■Main applications
・Weather Station (AWOS - Automatic Weather Observation System)
・Environmental monitoring, weather/environmental data logging
・Measurement lab/research institute
・Automobile exhaust gas test site
・Clean room monitoring ・Atmospheric pressure correction/control
・Performance evaluation and testing of internal combustion engines and combustion engines
