Working Principle:

MS13 is based rugged ceramic sensor element that is suitable for measuring over-pressure and under-pressure. The applied pressure deforms measuring membrane causing change in resistance on the attached measuring bridge. This change in resistance is mapped by electronic module and transformed into display, switch contacts or standard analog output signal.
The optional output signal can be dampened, spread, inverted and transformed via a table function even if it is non-linear. Overstepped limits can be visualised with LCD color change display.
The unit is configured with a keyboard or by means of remote configuration from PC.
