Frequently Asked Questions (FAQ)
Q
What is the protection grade of this pressure sensor, and is it suitable for harsh environments?
A
This pressure sensor carries an IP65 protection rating, which means it is fully dust-tight and protected against low-pressure water jets. It is well-suited for demanding industrial environments such as pipeline systems, air compressors, and air leak testing applications.
Q
What pressure ranges does this sensor support?
A
The sensor supports three rated pressure ranges: high pressure (0.000～1.999MPa), positive pressure (-0.100～1.000MPa), and compound pressure (-100～100kPa). The withstand pressures are 3.0MPa, 1.5MPa, and 500kPa respectively, ensuring reliable performance across a wide range of applications.
Q
Does this sensor support RS485 communication, and what is the maximum communication distance?
A
Yes, the sensor supports RS485 communication with a maximum connection distance of ≤1200m. It also supports multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, making it flexible for various industrial network configurations.
Q
What types of gases or fluids is this sensor compatible with?
A
The sensor is designed for use with non-corrosive fluids compatible with SUS316 stainless steel and FKM (Viton) materials. It is commonly used in applications involving air, nitrogen, and other non-corrosive industrial gases.
Q
What is the response time of this pressure sensor, and can it be adjusted?
A
The default response time is ≤2.5ms, which is ideal for fast-changing pressure monitoring. It can also be configured to longer intervals: 25ms, 100ms, 250ms, 500ms, 1000ms, or 1500ms, depending on the requirements of your application.
Q
What interface diameters are available, and what output types does the sensor offer?
A
The sensor is available in multiple interface diameters: RC1/8", VCR1/4", R1/4", and 1/4". The output type is open collector (supporting both NPN and PNP), with up to 2 outputs available, providing flexible integration into various control systems and PLCs.
