Frequently Asked Questions
Q
What pressure types does this pressure sensor support?
This pressure 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), making it versatile for a wide range of industrial applications.
Q
What is the IP protection rating of this pressure sensor?
The sensor is rated IP65, which means it is fully dust-tight and protected against low-pressure water jets from any direction. This makes it suitable for use in industrial environments where dust and moisture may be present.
Q
What types of gases are compatible with this pressure sensor?
This sensor is designed for use with filtered air and non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable gas media. Typical applications include pipeline pressure monitoring, air leak testing, F.R.L systems, gas storage cylinders, adsorption verification, and air compressors.
Q
Does this sensor support RS485 communication, and what baud rates are available?
Yes, the sensor supports RS485 communication with a maximum connection distance of up to 1200 meters. It is compatible with multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, offering flexible integration into various industrial control and monitoring systems.
Q
What is the operating temperature range and storage temperature range for this sensor?
The ambient operating temperature range is 0℃ to 50℃, with a humidity range of 35～85% (no water condensation). For storage, the temperature range is -10℃ to 60℃ without water condensation or freezing, ensuring the sensor remains reliable across varying environmental conditions.
Q
What output types and response times does this pressure sensor offer?
The sensor provides open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The response time is ≤2.5ms by default and can be configured to 25, 100, 250, 500, 1000, or 1500ms to suit different application requirements. The display refresh rate is 5 times per second for real-time monitoring.
