High-precision atmospheric pressure transmitter for gauge micro-pressure and micro-differential pressure measurement.
■Atmospheric pressure transmitter that measures gauge pressure or gauge differential pressure in the range of 10hPa to 200hPa and converts it to an analog output of current or voltage. ■Suitable for any application involving non-corrosive air or gas. ■Enables extremely high accuracy and stability in atmospheric pressure measurement thanks to the built-in piezoresistive sensor. It exhibits low hysteresis and excellent performance in reproducibility and temperature characteristics. ■All models are factory calibrated for accuracy before shipment, allowing for immediate installation and use. ▼Two types of output: 4-20mA (HD408T) / 0-10V (HD4V8T) ▼For gauge micro-pressure/micro-differential pressure monitoring in the measurement range of 10hPa to 200hPa ▼Extremely high measurement accuracy and long-term stability with piezoresistive sensor ▼Low hysteresis with excellent measurement reproducibility and temperature characteristics ▼Compact size (66×60×35mm) allows for installation in narrow spaces
