▋ FAQ


Q:How to wire the transmitter correctly? 

A:Follow the wiring diagram. Incorrect wiring will result in no signal output due to internal protection. Warm up for 30 minutes after powering on for stable signals.

Q:What media is it suitable for?

A:Use in media that doesn't corrode silicon or stainless steel (except special corrosion-resistant models).

QWhat are the pressure limitations?

A:Maximum pressure must not exceed rated overload. Avoid direct contact with conductive orcorrosive liquids/gases on the back pressure side. Keep air vents unblocked.

Q: Any precautions for the pressure output hole and diaphragm?

A:Avoid inserting sharp objects into the output hole. Do not touch the diaphragm.

Q:How to ensure its precision?

A:Handle with care, avoid dropping, clamping, dismantling, or poking with sharp metal objects.

Q:What to do if there's abnormal output? 

A:Stop and check. If a product defect, return with the warranty card and manual for repair or replacement.

Q:Can I disassemble or modify it?

A:No, unless you are a professional.
