oem  pressure gauge manometer

The  specification of  oem  pressure gauge manometer

1, the temperature characteristics: Since the diaphragm seal pressure gauge system is filled by a fluid pressure medium is passed, because the temperature coefficient of volume expansion of the sealing liquid, with the pressure-receiving portion of the pressure meter shows the temperature rise value is also increased, and the temperature affect the amount of sealing fluid expansion coefficient, the membrane stiffness and the pressure receiving portion temperature, especially for the low range of pressure gauges, the effect is more pronounced. General provisions of the pressure receiving portion temperature error is not more than 0.1% / ℃. Therefore, the total temperature diaphragm pressure gauge is normally provided by general-purpose instrumentation and temperature affect the amount of pressure on the diaphragm device Ministry temperature affect the amount of the sum of both
