Choosing PVC, PUR, FEP and TPE cable types

When specifying the electrical connection for submersible types of the LMP, LMK and DCL series of liquid level sensors, you will need to choose from a selection of cable types.

The choice of cable will depend on your budget, application environment, and liquid compatibility.

Below is a summary of the properties of each cable to help make a better decision on the most appropriate cable for your application.

FEP vs TPE for Diesel

Is a FEP or TPE outer cable material preferred for immersing in diesel? TPE seems to be a common choice for marine approved applications, but what’s the reason?

TPE is more robust, resistant to seawater and rated higher for hot environments.

FEP is better with diesel in non-marine applications, but TPE is also acceptable.
