Frequently Asked Questions
Q
What industries is this pressure sensor suitable for?
This pressure sensor is widely applicable across multiple industries, including pipeline pressure monitoring, air leak testing, F.R.L systems (Filter, Regulator, Lubricator), gas storage cylinders, adsorption verification, and air compressors. Its versatile pressure range and compact design make it ideal for both industrial automation and pneumatic control applications.
Q
What are the available pressure types and their rated ranges?
The sensor supports three pressure types: Micro pressure with a rated range of -10～10kPa, Positive pressure with a rated range of -0.100～1.000MPa, and Compound pressure with a rated range of -100～100kPa. Each type also has a corresponding withstand pressure rating to ensure safe operation under peak conditions.
Q
Does this sensor support RS485 communication, and what is the maximum connection 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, making it suitable for long-distance industrial data transmission and integration with PLCs or SCADA systems.
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 requirements.
Q
What type of gases can this sensor be used with?
The general type is compatible with air, non-corrosive, and non-flammable gases. A water-resistant type is also available, which is suitable for air with condensed water, non-corrosive, and non-flammable gases. It is not recommended for use with corrosive or flammable gas media.
Q
What are the operating and storage temperature and humidity conditions?
The sensor operates within an ambient temperature range of 0～50℃ and a humidity range of 35～85% (no water condensation). For storage, the temperature range extends to -10℃～60℃ without water condensation or freezing. These specifications ensure reliable performance across a wide range of environmental conditions.
