❓ Frequently Asked Questions
Q
What pressure types does this pressure sensor support?
This pressure sensor supports three pressure types: micro pressure (rated range -10~10kPa), positive pressure (rated range -0.100~1.000MPa), and compound pressure (rated range -100~100kPa). Each type has its own withstand pressure rating to ensure safe and reliable operation across different application scenarios.
Q
What is the protection grade of this pressure sensor?
The sensor carries an IP40 protection rating, which provides protection against solid objects greater than 1mm in diameter. It is suitable for general industrial environments. For applications involving condensed water, the water-resistant type is recommended, which supports air with condensed water that is non-corrosive and non-flammable.
Q
What communication interfaces and baud rates are supported?
The sensor supports RS485 communication with a maximum connection distance of up to 1200m. It is compatible with multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, making it flexible for integration into various industrial automation and monitoring systems.
