The 'Optima' series employs the established measurement principle of pressure sensitive diaphragm / LVDT. PSM’s unparalleled experience in the use of this technology in many thousands of applications results in a transmitter designed to perform accurately and reliably in the most demanding and arduous duties.
Diaphragms are produced in corrosion resistant alloys and are offered in a number of “nominal” ranges, each engineered for optimum performance at it’s measurement span. Diaphragm travel is limited by mechanical design, providing unmatched tolerance to high overload and shock conditions.
  
Construction

TIG fusion technology and Mass Spectrometry analysis ensures complete integrity of all welded joints. Thermal stress relief techniques ensure long-term service stability.
 

Through tank construction is standard.

All hygienic sensors are supplied with improved temperature compensation (co-effecient to +/- 0.02% per deg C) as standard to cope with the significant temperature fluctuations during ‘Cleaning In Place’ processes (CIP)

In addition, the Hygienic 319ST (through tank mounting) is profiled to directly replace the obsolete pneumatic sensors on force balance type systems to enable easy replacement with electronic systems.
