Yes, the sensor supports RS485 communication with a maximum connection distance of ≤1200m. It also supports multiple baud rates: 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, providing flexible integration into various industrial control 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 not recommended for use with highly corrosive gases or liquids that could damage these materials.
Q
What output types are available, and how many outputs does the sensor support?
The sensor features an open collector output supporting both NPN and PNP configurations, with up to 2 outputs available. The output voltage ranges from 0.6V to 5V (±2.5%F.S), and the load current is ≤200mA, making it compatible with a wide range of PLCs and control devices.
Q
What is the response time of this pressure sensor, and can it be adjusted?
The default response time is ≤2.5ms, which is ideal for fast-reacting systems. Additionally, the response time can be manually configured to 25ms, 100ms, 250ms, 500ms, 1000ms, or 1500ms, offering flexibility for different application requirements such as adsorption verification or air leak testing.
