Frequently Asked Questions (FAQ)
Q
What pressure types does this pressure sensor support?
This pressure sensor supports three pressure types: compound pressure (±100kPa / ±500kPa), positive pressure (up to 1.5MPa withstand), and vacuum pressure (0～-101.0kPa rated range). It is versatile for a wide range of industrial pneumatic applications.
Q
What is the communication interface and maximum communication distance?
The sensor features RS485 communication with a maximum connection distance of ≤1200m. It supports multiple baud rates including 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, making it suitable for long-distance industrial network integration.
Q
What gases is this sensor compatible with?
This sensor is designed for use with air and other non-corrosive, non-flammable gases. It is not suitable for corrosive or flammable gas media. Typical applications include pipeline pressure monitoring, air leak testing, air compressors, and F.R.L 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℃. 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 output type does this sensor provide, and what are the electrical specifications?
The sensor provides an open collector output supporting both NPN and PNP configurations, with up to 1 channel output. The load current is ≤200mA, no-load current consumption is ≤40mA, and the output voltage range is 0.6V～5V ±2.5%F.S. The wire uses an oil-resistant PVC cable (0.15mm²).
Q
What are the operating and storage temperature/humidity conditions?
The ambient operating temperature range is 0～50℃, with a humidity range of 35～85% (no water condensation). For storage, the temperature range is -10℃～60℃ without water condensation or freezing. The temperature characteristic is ±3%F.S referenced at 25℃ across the full operating range.
