DPS 4000 – Digital Pressure Transducer

DPS 4000 Series: Digital Pressure Transducers


The DPS 4000 Series is a state of the art range of digital output pressure transducers featuring a CANbus serial communications interface.


Fully temperature corrected pressure readings are output as a digital word in any one of 24 engineering units, requiring no user system set-up or calibration. The integral digital electronics enhance performance to levels unmatched by traditional analog transducers.

Pressure Measurement

Operating Pressure Ranges

Zero based ranges: 5 psi*, 10, 15, 30, 50, 100, 150, 300, 500 and 1000 psig (350 mbar, 700mbar, 1, 2, 3.5, 7, 10, 20, 35, 70 bar), absolute or differential.

Bi-directional gauge and differential ranges available on request.

*5 psi gage, or differential only

Overpressure The pressure range can be exceeded by the following with negligible effect on calibration:
Positive side: 4 x full scale (FS) (2000 psi maximum) (140 bar maximum)
Negative side: 2 x FS (150 psi maximum) (10 bar maximum).
Line Pressure 500 psi (35 bar) maximum (differential model only).
Positive Pressure Media Fluids compatible with Stainless Steel 316 L and Hastelloy C276.
Excitation Voltage 7.5 to 30 VDC.
Output Configuration CANopen digital data via CANbus interface. User configurable pressure reading
Software Protocol In accordance with:
  • DS301 V 4.01 (CANopen)
  • DS404 V 1.0 (Analog input device profile)
  • DSP 305 V 1.0 (Layer setting service)


Accuracy 0.2% reading down to 50% FS, then 0.1% FS to zero. Includes all errors over 50°F to 140°F (10°C to 60°C).
Long Term Stability Typically less than 0.08% FS per annum.
Operating Temperature Range -40°F to 175°F (-40°C to 80°C). Insulation Resistance Greater than 100 MΩ at 500 VDC
Mechanical Shock 1000 g, 1 mS half sine pulse in three mutually perpendicular axes will not affect performance.
Vibration Response <0.05% FS/g at 30 g peak 10 Hz to 2 kHz, limited by 0.5 in (12 mm) double amplitude.
