Measuring membrane

The measuring membrane is connected to the pressure transmitter via oil-filled capillary tube.

Used for measuring relative pressure where membrane attachment is required.

Membrane offsets are used where the process medium is not wanted into the pressure transmitter.

Either due to media resistance or high temperature application.

It could also be by measuring on media containing particles that can damage the measuring membranes, or by a medium being kept heated, where an unintended process stop (cooling) can solidify the medium, thereby destroying the pressure transmitter.

For assignments with inserts, Insatech also has the supplier Badotherm, which allows for a larger selection of inserts.

Also used for pressure measurement of liquids, gas and steam, can measure fluid level and perform density calculation.

Insatech can offer a wide range of manifolds as well as stakes.
