Frequently Asked Questions
Q
What pressure ranges does this pressure sensor support?
This pressure sensor supports three pressure types: high pressure (0.000～2.000MPa), positive pressure (-0.100～1.000MPa), and compound pressure (-100～100kPa). The withstand pressure reaches up to 3.0MPa for high pressure models, ensuring reliable performance across a wide range of industrial applications.
Q
What is the protection grade of this pressure sensor?
The sensor is rated at IP65, which means it is fully protected against dust ingress and resistant to low-pressure water jets from any direction. This makes it suitable for use in demanding industrial environments such as pipeline monitoring, air compressors, and gas storage systems.
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 ≤1200m. It supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, making it highly flexible for integration into industrial automation and monitoring systems.
Q
What types of gases or fluids is this sensor compatible with?
The sensor is compatible with non-corrosive fluids suitable for SUS316 stainless steel and FKM (fluoroelastomer) materials. It is ideal for use with clean air, nitrogen, and other non-corrosive gases commonly found in industrial pneumatic and process control applications.
Q
What output types are available and what is the response time?
The sensor features an open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The standard response time is ≤2.5ms, and it can be flexibly configured to 25, 100, 250, 500, 1000, or 1500ms depending on application requirements.
Q
What are the operating and storage temperature ranges for this sensor?
The sensor operates within an ambient temperature range of 0～50℃ and can be stored at temperatures between -10℃ and 60℃ without water condensation or freezing. The operating humidity range is 35～85% (no condensation), ensuring stable performance in a variety of environmental conditions.
