Description

The model A-10 pressure transmitter for general industrial applications is not only notable for its compact design, but it

also oers excellent quality at an extremely competitive price.

The user can choose between a non-linearity of 0.25 %

and 0.5 %. A free test protocol provides information on the

measuring points recorded during manufacture.

Pressure transmitter, model A-10

The model A-10 is set up for worldwide use through the

international cULus and EAC certication. The various

pressure units and process connections required for

particular operating conditions are available at short notice.
