Automotive Pressure Transducers use CANbus.
Druck announce a new series of compact and rugged
digital pressure transducers for highly accurate and
reliable pressure measurements whilst operating in the
demanding environments of modern automotive test
stands, for example engine and powertrain test facilities.
From the testing of new lubricants through to the development of
high performance racing engines and powertrains, demands
placed upon test stands constantly increase. The Druck DPS 4000
series has been developed using extensive experience of the
automotive industry.
Modular design allows configurations to ensure complete
measurement capability, ranging from oil/fuel and turbo pressures
to monitoring of gearbox oil and clutch assemblies.
The DPS 4000 series features a digital CANbus serial communications
interface. Fully temperature corrected pressure readings are output
as a digital word at up to 100 Hz in any one of 24 engineering units,
requiring no user system set-up or calibration. The integral digital
electronics also enhance performance to levels unmatched by
traditional analogue transducers: 0.2% reading for values above
50% FS and 0.1% FS for readings below 50%FS, inclusive of all
thermal effects over a compensated temperature range of 10 to
60 deg C.
Communications software is based upon the CANopen protocol.
This offers the user access to last/next calibration date, calibration
routines and serial number identification amongst others.
Capable of operation from a range of supply voltages (including
batteries) the DPS 4000 is also fully input/output isolated for
complete system protection and associated user confidence.
Pressure ranges are available from 350mbar to 70 bar including
gauge, absolute and differential versions. Together with 400%
overpressure, a choice of physical configurations and the ability
to accommodate customer specific requirements, the DPS 4000
is ideally matched for meeting the diverse challenges presented
by automotive test stand applications.
