Summary of Contents for SMAR SR301

  • Page 3 Introduction INTRODUCTION The SR301 is a Remote Seal that allows the pressure transmitter to make measures in situations where the immediate contact of the transmitter diaphragm with the process fluid it is not allowed. The remote seal is made up by one connection with the diaphragm and one capillary connection with filling fluid.
  • Page 4 Thus, in choosing the seal size these factors must be considered according to each case to guarantee excellent performance and long-life span. This manual was made to help install, operate, and maintain the SR301. It contains information about transmitter/seal assembly, organized in the following categories: •...

    Selection Calculation of Temperature Errors Remote seal temperature errors are due to the volume variation of the filling fluid in the transmitter body, extension, capillary and remote seal. Following, the necessary information for the error calculation are described. Equations To obtain a volume variation for each leg of the remote seal, the temperature variation in the seal, in the capillary and in the transmitter body must be known and then insert the value in the equations below.
