Frequently Asked Questions
What is the maximum withstand pressure of this sensor?
The sensor supports a maximum withstand pressure of up to 3.0 MPa for high-pressure setups, 2.0 MPa for positive pressure systems, and 500 kPa for compound pressure applications.
What protection rating does this pressure sensor offer?
This unit features an IP65 protection grade, ensuring robust resistance to dust ingress and low-pressure water jets from any direction.
How long is the maximum RS485 communication distance?
The RS485 communication link can operate reliably over a maximum connection distance of up to 1200 meters.
What display colors are available on the screen?
The display supports 3 distinct, highly visible colors: white, red, and orange, which can be configured to represent different pressure statuses.
What type of fluid or gas is compatible with this sensor?
It is designed for non-corrosive fluids and gases that do not degrade or react with SUS316 stainless steel and FKM (Fluorocarbon rubber) materials.
Can the response time of the sensor be adjusted?
Yes, while the standard response time is ≤2.5ms, it can be adjusted to 25, 100, 250, 500, 1000, or 1500ms depending on your system's filtration requirements.
