Q
What is the maximum working pressure this pressure gauge can handle?
The gauge has a working pressure of 200 Bar, a test pressure of 400 Bar, an overpressure rating of 520 Bar, and a burst pressure of 1,000 Bar, making it suitable for demanding high-pressure applications.
Q
Is this pressure gauge suitable for outdoor or wet environments?
Yes. The gauge carries an IP65 waterproof rating, which means it is fully protected against dust ingress and low-pressure water jets, making it reliable for outdoor and washdown environments.
Q
What thread types are available for installation?
The pressure gauge supports both 1/4 BSP and M14×1.5 thread connections, providing flexibility for various installation requirements across different systems and equipment.
Q
What power supply voltage does this gauge require?
The gauge supports both 12V and 5V DC power supply. The wiring is straightforward: Red wire connects to DC power (12V or 5V), White wire carries the output signal, and Black wire is ground.
Q
Can this gauge be used in hydrogen or natural gas applications?
Yes. The gauge is specifically designed to resist sulfide attack for hydrogen fueling and H2S gas handling, and it also supports CNG/LNG applications with pressures up to 6,000 psi with optional high-pressure connections.
Q
How do the LED indicator lights indicate pressure levels?
The LED indicator system uses a red light and up to four green lights to show pressure status. At 0–3 MPa the red light is on; at 5 MPa one green light activates; at 10 MPa two green lights are on; at 15 MPa three green lights are on; and at 20 MPa or above all four green lights are illuminated with the red light off.
