Huba Pressure sensor 511

These compact OEM pressure transmitters type 511 meet 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 20 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.

 Compact, rugged construction for highest operational reliability
 No media egress when exceeding rupture pressure
 Negligible temperature influence on accuracy
 Excellent EMC capacity
 Saving time by quick cable mounting by the customer with swift connector
