Frequently Asked Questions
What types of gases are compatible with this sensor?
The sensor is suitable for air, non-corrosive, and non-flammable gases. A specialized water-resistant type is available for air containing condensed water.
What is the response time of the pressure switch?
The default response time is very fast at ≤2.5ms. However, it can be adjusted to 25, 100, 250, 500, 1000, or 1500ms depending on your application needs.
Does it support remote communication?
Yes, it supports RS485 communication with a maximum connection distance of up to 1200 meters, supporting baud rates from 9600bps to 115200bps.
What is the protection grade and durability of the device?
The device features an IP40 protection grade. It is designed to withstand impacts of up to 10G and vibrations with an amplitude of 1.5mm across X, Y, and Z directions.
Can the display color be customized?
The display features 3 distinct colors (white, red, and orange) which can be used to indicate different status conditions or pressure levels.
