The sensitive element of the YZB491 differential pressure transmitter is a kind of integrated all-welded (without sealing ring) differential measuring element. The spaces between the chip and the two convoluted diaphragms are injected with silicone oil. The differential pressure exerts a force on the convoluted diaphragms at the two ends, squeezing the silicone oil in between which then transmits it to the sensitive chip. And the sensitive chip is connected with signal treatment circuit by conductor wire. The piezoresistive effect of semiconductor silicon material is employed by the product to realize the conversion between differential pressure and electric signal. Due to the good linear relationship between the signal outputted by the Wheatstone bridge on the sensitive chip and the differential pressure, the differential pressure can be measured correctly. It is suitable for measuring differential pressures for various air or liquid pipes of different industries, such as oil, chemical and electrical industries, as well as hydrological sector.

Notes for Selection
1. It is recommended to install three valve groups between the measuring point and the transmitter to ensure that the measured medium is stressed into the positive and negative chambers of the transmitter slowly and evenly, so that the reliable operating of the transmitter can be ensured.
2. It is recommended to make the pressure interfaces at the two ends horizontal upon installation, so as to minimize the impact of installation on the product.
3. Upon model selection, please consider that the static pressure at the measuring point shall not be over 20MPa and the overpressure on the positive and negative chambers of the transmitter shall not be over the specified value of the product.
4. The digital display meter document is included in the document for YZB480 pressure transmitter.
5. For any special requirement, please feel free to contact us and show it in the purchase order.
