? 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 micro, positive, and compound pressure measurement needs.
Q
What is the protection grade of this pressure sensor, and is it suitable for harsh environments?
The sensor carries an IP65 protection rating, making it dust-tight and protected against water jets. It operates reliably in ambient temperatures from 0℃ to 50℃ and humidity levels of 35～85% (without water condensation), making it suitable for a wide range of industrial environments.
Q
What communication interfaces and baud rates does this sensor support?
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, offering flexible integration into various industrial control systems.
Q
What types of gas is this pressure sensor compatible with?
This sensor is designed for use with filtered air and non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable gas environments. Typical application scenarios include pipeline pressure monitoring, air leak testing, F.R.L units, gas storage cylinders, adsorption verification, and air compressors.
Q
What is the display accuracy and response time of this sensor?
The display accuracy is ±1%F.S ±1digit at a reference temperature of 25±3℃, with a display refresh rate of 5 times per second. The response time is ≤2.5ms by default, and can be configured to 25, 100, 250, 500, 1000, or 1500ms depending on the application requirement.
Q
What output types are available and what is the output voltage range?
The sensor provides an open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The output voltage ranges from 0.6V to 5V (±2.5%F.S at rated voltage). The load current is ≤200mA, and no-load current consumption is ≤40mA, ensuring energy-efficient operation.
