BaseCal – a Diaphragm Seal Performance Tool

You know your project inside out – specifications, requirements and variables. What you may not be sure about is which Diaphragm Seal will best suit your needs, so that’s where we come in.

We’re excited to bring you BaseCal – a web-based performance tool that helps you understand the effect of different variables and conditions on your diaphragm seal application.


What is a diaphragm seal application?

A diaphragm seal application consists of three main components: a measuring instrument, one or two diaphragm seals and either a direct mount construction or capillary lines. This is filled with a fill fluid.


During its service life, a diaphragm seal application is exposed to different conditions and factors that can influence performance. These can include varying temperatures, location, fluctuating pressures and choice of instrument. Each of these factors can have an effect on the performance of the diaphragm seal application, and you can use BaseCal to decide what type of seal application will best suit your predicted variables.

When calculating effects of these conditions, BaseCal takes the worst-case tolerance or error into account for these factors:



  • Process temperature effect
  • Ambient temperature effect
  • Mounting effect
  • Accuracy effect
  • Static pressure effect
  • Total probability error




Why is it important to use a correctly engineered diaphragm seal application?

Diaphragm seals are often used in extreme or hazardous environments. It is therefore important to accurately engineer your seal to suit your project conditions, in order to read precise and correct measurements of your process media.
