Shanghai Xuan Ye pressure sensor quality, and their pressure transmitter stability is good?

Shanghai Xuan Ye pressure sensor quality, and their pressure transmitter stability is good?

Answer:

Xuan Ye measurement and control of the company's main agent GE-druck, Hitt (Setra), Bode (BD) and other imported brand pressure transmitters, and now also do the production, the flagship of exquisite pressure transmitter. Before the use of their home products, prices a little higher than the domestic similar products, the accuracy of 0.5%FS in general, but the quality is very good, especially the stability than imported brands but also a little better (think). If you measure the vacuum, can choose -100kpa-0 or 0-100kpa absolute pressure range, measurement methods and reference starting point is different, but the effect is no difference, this mainly depends on the specific needs of the scene and measurement conditions, these views for reference, I hope to help you.
-100kpa-0 negative pressure sensor and 0-100kpa absolute pressure sensor measure vacuum only reference starting point is not the same, if the same accuracy, the same type of sensor, the same effect. This sensor has not been used before, but the situation
Select -100kpa-0 negative pressure sensor or 0-100kpa absolute pressure type, all OK; I have used.
