Process Specifications required for seal selection

To select an appropriate assembly, the process conditions, installation requirements, and overall system performance must be taken into account. Here are some factors that will need to be considered for proper selection.

• What are the minimum and maximum pressures that are to be measured?
• What are the minimum and maximum pressures in the process?
• What are the minimum and maximum ambient temperatures?
• What are the minimum and maximum process temperatures?
• How fast will the measured variable change?
• Where will the transmitter be installed?
• Is the process under vacuum?
• Is the process connection cleaned? With what type of solution?
