What Is Differential Pressure Sensor

The sensor is invented by Starwin specialized apply to gas wall hung boiler and gas water heater for instead of pressure switches. The failure rate of pressure switches is 2-4%,while The failure rate of pressure sensors is 0.0001%.

Advantages

Why Use Our Differential Pressure Sensor To Instead Of Pressure Switch

*Cost Effective: our pressure sensor cost is lower than pressure switches.
*High precision: the measuring accuracy can reach to ±1%FS.
*Completely solve the malfunction rate of pressure switch long-time use.
*Real-time monitoring of pressure, accurate matching, efficient combustion, safe discharge.
*Against external mutation pressure.
*Keep constant temperature
*Can set up multi-point of pressure protection, safe and secure.
*No accuracy attenuation with long-term use.
*Wide temperature compensation range.
*Quick response.

Film Bongding IssueThe inner cavity of the shell is planar structure, which is easy to bond.The shell cavity is non-planar structure, and the piston side is serrated design, which makes it difficult to bond.The inner cavity of the shell is non-planar structure, the piston side is thickened, and the surface of the plate is added with tibial strip and convex point, which will not make it to bond.
leakproofnessPlane sealing effect is not good, and the upper and itslower shell expansion coefficient is inconsistent so it is easy to leak.Groove sealing effect is good, and its the upper and lower shell expansion coefficient is consistent, which is going to leak casually.The groove sealing effect is good, and Starwin adopts imported polymer material by adding special fiber, which will not leak any more.
Data Excursion IssueThe original calibration d calibration on and off data drifts with the use of time,which will resulting in abnormal working properly.The original calibration d calibration on and off data drifts with the use of time,which will resulting in abnormal working properly.Built-in temperature compensation circuit, adopting linear frequency output, but also can be arbitrarily set a number of on/off points without any data excursion.
Resistance&StabilityThe terminal is easy to oxidize, the with poor contact which will lead to false alarm and can not work normally.The terminal is easy to oxidize, the with poor contact which will lead to false alarm and can not work normally.Using electromagnetic induction technology without terminal and mechanical friction, which can completely eliminate contact oxidation and poor contact fault.

Together, we accelerate the breakthroughs that advance our world.
