Frequently Asked Questions
Q
What pressure ranges does this pressure sensor support?
This sensor supports three pressure types: micro pressure (-10～10kPa), positive pressure (-0.100～1.000MPa), and compound pressure (-100～100kPa). The withstand pressure ratings are 20kPa for micro pressure, 1.5MPa for positive pressure, and 500kPa for compound pressure.
Q
What types of gas is this sensor compatible with?
The sensor is compatible with air and non-corrosive, non-flammable gases. The general type is suitable for standard dry air, while the water-resistant type can handle air with condensed water, as long as the gas remains non-corrosive and non-flammable.
Q
What communication interfaces and baud rates does this sensor support?
The sensor supports RS485 communication with a maximum connection distance of up to 1200m. It is compatible with multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, offering flexible integration into various industrial systems.
Q
What is the operating temperature range and storage temperature range?
The ambient operating temperature range is 0～50℃, while the storage temperature range is -10℃～60℃ (without water condensation or freezing). The humidity requirement for both operation and storage is 35～85% with no water condensation.
Q
What output types are available and what is the response time?
The sensor provides an open collector output, available in either NPN or PNP configuration, supporting up to 1 channel output. The response time is ≤2.5ms by default, and can be configured to 25, 100, 250, 500, 1000, or 1500ms depending on application requirements.
Q
What industries and applications is this pressure sensor suitable for?
This sensor is widely used across multiple industrial scenarios, including pipeline pressure monitoring, air leak testing, F.R.L (Filter, Regulator, Lubricator) systems, gas storage cylinders, adsorption verification, and air compressors.
