FAQ
Q: What types of media can this pressure sensor measure?
A: The 17-4PH stainless steel sensing diaphragm offers excellent compatibility with a wide range of media, including various gases (air, nitrogen, etc.) and liquids that are compatible with stainless steel, such as water, hydraulic oil, and some fuels. It is not suitable for corrosive media that attack stainless steel.
Q: My application has high electrical noise. How can I ensure a stable signal?
A: For environments with significant electromagnetic interference (EMI), we strongly recommend using a shielded cable. Proper grounding of the cable shield is crucial to minimize noise and ensure signal integrity.
Q: Do you offer custom process connections or specifications?
A: Yes, as a manufacturer, we provide OEM and customization services. Please contact our technical team to discuss your specific requirements for connection types, cables, ranges, or other parameters.
