PDCR/PMP 4300 Series

Druck motorsport/automotive pressure transducers
Success in motorsport depends on hundreds of components
working together under extreme conditions, and Baker Hughes
continues to develop Druck pressure transducers that give theultimate performance. Druck motorsport sensors have becomea world-leading product line used in Formula 1, World Rally
Championship and the Indy Racing League, amongst others.
The PDCR/PMP 4300 Series is the latest in the range of productsthat for many years has been “fine tuned” in design to suit allchassis and engine pressure measurement requirements.

Features• Race proven technology• High temperature capability to 350°F (175°C)• Amplified or millivolt output• Stainless steel or titanium construction• Fully EMC protected• Flexible mechanical/electrical interface options

Race proven technology

Flexible design

Since 1990 Druck products have been successfully applied
to motorsport, and the PDCR/PMP 4300 Series is a highperformance pressure sensor for this harsh environment
application.

The pressure sensing module and the electronics form acompletely flexible core. Various configurations of electricalterminations and pressure connectors are available in bothstainless steel and titanium. Baker Hughes has considerable
experience in solving specific application problems by
developing standard designs to suit customer-specificapplications.

Reliability remains at the forefront of Baker Hughes’s design
and build philosophy. The combination of high technology
sensing elements and advanced signal conditioning andpackaging techniques provides reliable and accuratepressure measurements.

High performance
Baker Hughes has a new advanced and comprehensive
silicon processing facility and is one of a few companies
turning raw silicon into finished pressure sensing products.
Each pressure module is fully temperature cycled to enhancelong-term measurement stability. All metalwork is welded
to form a rugged housing. Upon completion of the electricalconnections the units are again thermally cycled to eliminate
any possible defects in application.
This rugged construction enables the 4300 Series to operate
under extreme temperature and vibration conditions.
