Frequently Asked Questions
Q
What types of pressure can this sensor measure?
A
This sensor supports three types of pressure measurement: compound pressure (-100～100kPa), positive pressure (-0.1～1MPa), and vacuum pressure (0～-101.0kPa), making it versatile for a wide range of industrial applications.
Q
What is the protection grade of this pressure sensor?
A
The sensor carries an IP40 protection grade, which provides protection against solid particles larger than 1mm. It is suitable for use in standard industrial environments where direct water exposure is not expected.
Q
What communication interfaces does this sensor support?
A
The sensor features RS485 communication with a maximum connection distance of up to 1200m. It supports multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, allowing flexible integration into various control systems.
Q
What gases is this sensor compatible with?
A
This sensor is designed for use with air and non-corrosive, non-flammable gases. It is not suitable for corrosive or combustible gas environments. Typical applications include pipeline pressure monitoring, air leak testing, air compressors, and F.R.L systems.
Q
What is the response time of the sensor, and can it be adjusted?
A
The default response time is ≤2.5ms, which is ideal for fast-changing pressure environments. Users can also configure the response time to 25ms, 100ms, 250ms, 500ms, 1000ms, or 1500ms depending on the application requirements.
Q
What is the operating temperature range and storage temperature range?
A
The sensor operates reliably within an ambient temperature range of 0℃ to 50℃. For storage, it can withstand temperatures from -10℃ to 60℃ without water condensation or freezing. The temperature characteristic is ±3%F.S referenced at 25℃.
