Frequently Asked Questions
Q
What types of pressure can this sensor measure?
This pressure sensor supports three types of pressure measurement: micro pressure (up to 20kPa), positive pressure (up to 1.5MPa), and compound pressure (up to 500kPa). The rated pressure ranges cover micro pressure (-10～10kPa), positive pressure (-0.100～1.000MPa), and compound pressure (-100～100kPa).
Q
What is the protection grade of this pressure sensor?
The sensor carries an IP65 protection rating, making it dust-tight and protected against low-pressure water jets. This makes it suitable for use in industrial environments where exposure to dust and moisture is a concern.
Q
Does this sensor support RS485 communication, and what is the maximum connection distance?
Yes, this sensor supports RS485 communication with a maximum connection distance of up to 1200 meters. It supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, offering flexible integration into various industrial communication networks.
Q
What gases are compatible with this pressure sensor?
The sensor is designed for use with filtered air and non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable gases. Typical applications include pipeline pressure monitoring, air leak testing, F.R.L systems, gas storage cylinders, adsorption verification, and air compressors.
Q
What is the operating temperature range and humidity tolerance?
The sensor operates within an ambient temperature range of 0～50℃ and can be stored at -10℃～60℃ (without water condensation or freezing). The humidity tolerance for both operation and storage is 35～85% with no water condensation allowed.
Q
What output types and response times does this sensor offer?
The sensor provides open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The response time is ≤2.5ms by default, and can be configured to 25, 100, 250, 500, 1000, or 1500ms depending on application requirements. The display refreshes 5 times per second for real-time monitoring.
