Please see GS01C25R01-01EN for more detailed information. The EJX910A uses the established DPharp pressure sensor technology that allows for simultaneous measurement of differential pressure and static pressure (absolute or gauge) from one sensor. Out of all the Yokogawa pressure transmitters, the EJX910A has the best accuracy for combined DP and SP measurement, which makes it an excellent choice for flow calculations with a YRTU.
