Frequently Asked Questions
Q
What is the protection grade of this pressure sensor, and is it suitable for harsh environments?
This pressure sensor carries an IP65 protection grade, which means it is fully dust-tight and protected against low-pressure water jets from any direction. It is well-suited for use in industrial environments involving dust, moisture, and general splash exposure.
Q
What types of gases can this sensor be used with?
The sensor is compatible with filtered air and non-corrosive, non-flammable gases. It is not recommended for use with corrosive chemicals, flammable gases, or liquids, as these may damage the internal components or cause safety hazards.
Q
What is the maximum RS485 communication distance supported by this sensor?
The sensor supports RS485 communication with a maximum connection distance of up to 1200 meters. It also supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, providing flexible integration into various industrial communication systems.
Q
What pressure ranges are available, and how do I choose the right one?
Three pressure types are available: Micro pressure (-10～10kPa), Positive pressure (-0.100～1.000MPa), and Compound pressure (-100～100kPa). Choose based on your application — micro pressure suits low-pressure gas detection, positive pressure is ideal for pipeline and cylinder monitoring, and compound pressure covers both positive and negative ranges for versatile use.
Q
What is the response time of this sensor, and can it be adjusted?
The default response time is ≤2.5ms, making it highly responsive for real-time monitoring. Additionally, the response time can be manually configured to 25ms, 100ms, 250ms, 500ms, 1000ms, or 1500ms, allowing users to balance speed and stability based on their specific application requirements.
Q
What output types does this sensor support, and how many outputs are available?
The sensor features an open collector output supporting both NPN and PNP configurations, with up to 2 output channels available. The load current is rated at ≤200mA, and the output voltage range is 0.6V～5V (±2.5%F.S), making it compatible with a wide range of PLCs and control systems.
