Frequently Asked Questions

What is the difference between a pressure sensor and a pressure switch?

A pressure sensor provides a continuous output signal (e.g., 4-20mA) proportional to pressure, while a pressure switch provides a discrete on/off signal at a set pressure point.

Are your sensors compatible with refrigerants?

Yes, our NPT1/8 and HVAC-specific sensors are designed to be corrosion-resistant and compatible with common refrigerants used in air conditioning and heat pump systems.

Do you offer custom pressure ranges?

Yes, we can customize pressure ranges, output signals, and mechanical connections based on your application requirements.

What certifications do your products have?

Our manufacturing processes follow international quality standards. While specific product certifications may vary, all units undergo rigorous in-house testing for reliability and performance.
