Frequently Asked Questions
Q
What pressure ranges does this pressure sensor support?
The sensor supports three pressure types: micro pressure (rated range -10～10kPa, withstand up to 20kPa), positive pressure (rated range -0.100～1.000MPa, withstand up to 1.5MPa), and compound pressure (rated range -100～100kPa, withstand up to 500kPa). This makes it suitable for a wide variety of industrial applications.
Q
What is the protection grade of this sensor, and can it be used in dusty or wet environments?
The sensor carries an IP65 protection rating, meaning it is fully dust-tight and protected against low-pressure water jets. It is well-suited for industrial environments where dust and moisture may be present, though it should not be submerged in water.
Q
What types of gases is this pressure sensor compatible with?
The sensor is designed for use with filtered air and non-corrosive, non-flammable gases. It is not suitable for corrosive chemicals, flammable gases, or liquids. Always ensure the medium is properly filtered before use to maintain measurement accuracy and sensor longevity.
Q
Does this sensor support RS485 communication, and what is the maximum cable distance?
Yes, the 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, providing flexible integration into various industrial control and monitoring systems.
Q
What is the display refresh rate and response time of the sensor?
The display refreshes at 5 times per second, ensuring real-time pressure readings. The response time is ≤2.5ms by default, and can be configured to 25, 100, 250, 500, 1000, or 1500ms depending on the application requirements, offering flexibility between speed and stability.
Q
What are the typical application scenarios for this pressure sensor?
This sensor is widely used across multiple industrial fields, including pipeline pressure monitoring, air leak testing, F.R.L (Filter, Regulator, Lubricator) systems, gas storage cylinders, adsorption verification processes, and air compressor systems. Its compact design and high accuracy make it ideal for both OEM integration and field installation.
