    ? Frequently Asked Questions
    QWhat pressure ranges does this pressure sensor support?
    The sensor supports three pressure types: micro pressure (-10~10kPa), positive pressure (-0.100~1.000MPa), and compound pressure (-100~100kPa). The withstand pressure varies accordingly — up to 20kPa for micro, 1.5MPa for positive, and 500kPa for compound pressure types.
    QWhat gases is this sensor compatible with?
    The sensor is suitable for air, non-corrosive, and non-flammable gases (general type). A water-resistant type is also available for use with air containing condensed water, provided the gas is still non-corrosive and non-flammable.
    QWhat communication interfaces and baud rates are supported?
    The sensor supports RS485 communication with a maximum connection distance of ≤1200m. It is compatible with baud rates of 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, offering flexible integration into various industrial systems.
    QWhat are the operating and storage temperature ranges?
    The ambient operating temperature range is 0~50℃. For storage, the sensor can withstand temperatures from -10℃ to 60℃, provided there is no water condensation or freezing during storage.
    QWhat output types are available for this sensor?
    The sensor provides an open collector output supporting either NPN or PNP configuration, with up to 1 channel output. The output voltage range is 0.6V~5V (±2.5%F.S at rated voltage), and load current is ≤200mA.
    QWhich industries and applications is this pressure sensor designed for?
    This sensor is designed for a wide range of industrial applications including pipeline pressure monitoring, air leak testing, F.R.L (Filter, Regulator, Lubricator) units, gas storage cylinders, adsorption verification systems, and air compressors.
