Frequently Asked Questions
Q
What types of pressure can this pressure sensor monitor?
This pressure sensor supports three pressure types: micro pressure (up to 20kPa), positive pressure (up to 1.5MPa), and compound pressure (up to 500kPa). The rated pressure ranges vary accordingly, covering a wide range of industrial applications including pipeline pressure monitoring, air leak testing, and gas storage cylinders.
Q
What is the protection grade of this pressure sensor?
The sensor carries an IP65 protection rating, making it dust-tight and protected against water jets. This ensures reliable performance in demanding industrial environments where exposure to dust and moisture is common.
Q
What communication interfaces and baud rates does this sensor support?
The sensor supports RS485 communication with a maximum connection distance of up to 1200 meters. It is compatible with multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, offering flexible integration into various industrial control systems.
Q
What gases are compatible with this pressure sensor?
This sensor is designed for use with filtered air and non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable media. Typical applications include compressed air systems, F.R.L. units, and adsorption verification setups.
Q
What is the operating and storage temperature range?
The sensor operates within an ambient temperature range of 0℃ to 50℃. For storage, it can withstand temperatures from -10℃ to 60℃ without water condensation or freezing. Humidity during both operation and storage should be maintained between 35% and 85% (non-condensing).
Q
What output types and response times does this sensor offer?
The sensor features open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The minimum response time is ≤2.5ms, and it can be configured to 25, 100, 250, 500, 1000, or 1500ms depending on application requirements. The display refresh rate is 5 times per second for real-time monitoring.
