Technical overview

These compact OEM pressure trans­mitters type series 511meet the high­est specification for mechanical
stress, EMC compatibility, and ope­rational reliability, which means that
this range is particulary suitable for
all demanding industrial applica­tions.

This sensor utilises a ceramic tech­nology, developed by Huba Control
and for the last 10 years, in millions
of applications, used in combina­tion with unique integrated elec­tronic design, means that the type
511 series has a high degree of accu­racy for all temperature ranges.
These units are available in small or
production quantities, with an ex­cellent price to performance ratio.

The distinct advantages

• Compact, rugged construction for
highest operational reliability

• Protection IP 67 standard

• No media egress when exceeding
rupture pressure (patented)

• Negligible temperature influence on
accuracy

• Excellent EMC-capacity

• Saving time by quick cable mounting
by the customer with Quickon­System
