Frequently Asked Questions
Q
What types of pressure can this pressure sensor measure?
This pressure sensor supports three types of pressure measurement: micro pressure (up to 20kPa withstand), positive pressure (up to 1.5MPa withstand), and compound pressure (up to 500kPa withstand). The rated pressure ranges cover micro, positive, and compound pressure scenarios to suit a wide range of industrial applications.
Q
What is the protection grade of this pressure sensor, and is it suitable for harsh environments?
The sensor carries an IP65 protection rating, meaning it is fully dust-tight and protected against low-pressure water jets. It operates reliably in ambient temperatures from 0℃ to 50℃ and humidity levels of 35～85% (non-condensing), making it suitable for a variety of industrial environments including pipeline monitoring and air compressor systems.
Q
Does this sensor support RS485 communication, and what is the maximum communication distance?
Yes, the sensor supports RS485 communication with a maximum connection distance of up to 1200 meters. It also supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, providing flexible integration with various control systems and PLCs.
Q
What types of gases 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 applications include pipeline pressure monitoring, air leak testing, F.R.L. units, gas storage cylinders, adsorption verification, and air compressors.
Q
What output types does this sensor provide, and how fast is the response time?
The sensor offers open collector output in either NPN or PNP configuration, supporting up to 2 outputs. 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.
Q
How accurate is this pressure sensor, and what is its vibration and impact resistance?
The sensor offers a display accuracy of ±1%F.S ±1digit (at 25±3℃) and a repeatability accuracy of ±0.3%F.S ±1digit. For vibration resistance, it withstands an amplitude of 1.5mm at 10Hz～55Hz～10Hz for 2 hours in each of the X, Y, and Z directions. For impact resistance, it endures 100m/s² (10G) with 3 impacts in each direction, ensuring durability in demanding industrial settings.
