Assembled, tested, and ready-to-install measuring equipment, with the exact configuration your process requires.

Types of Instruments

Materials and coatings

Mounting and configuration options

We offer all the industry-standard technical variants to suit every application and environment.

Direct mount

The diaphragm seal attaches directly to the instrument (transmitter, pressure gauge, pressure switch, etc.), minimizing space and ensuring maximum mechanical rigidity.

Capillary assembly

Remote installation using a flexible capillary, allowing the instrument to be separated from the process point (due to temperature, accessibility, vibration, etc.). Various lengths, diameters, and protections are available.

In-line assembly

Special configuration for direct integration into pipes, useful in high flow applications or to prevent product accumulation.

Sanitary connections
