DS85-P

Product catalog summary

Device Overview:
The DS85-P is a differential pressure sensor designed for measuring small differential pressures of non-aggressive gases, primarily air. It features a diaphragm element and offers selectable pressure ranges from 50 Pa to 6000 Pa, adjustable via a DIP-switch. The sensor provides an analogue output of 0...10 V and is housed in a solid plastic case with protection class IP65.

Specifications:

Pressure Ranges: 50 Pa to 6000 Pa, with four selectable calibrated ranges per unit.
Overpressure Capacity: 0.2 bar
Static Pressure: Maximum 0.2 bar
Pressure Connections: Hose liners with a diameter of 5 mm
Case Material: Ultramid, black, IP65 protection
Dimensions: Diameter 70 mm, Depth 50 mm
Electrical Connections: 3-wire, color-coded, with protection against incorrect connections
Supply Voltage: 15...30 Vdc or 24 Vac ± 15%
Current Consumption: Approximately 10 mA at 24 Vdc
Output: 0...10 V, three-wire connection
Characteristic: Linear
Operating Temperature: -20 to +50 °C
Weight: Approximately 90 g
Mounting Position: Vertical, with a 25 Pa alteration at 90° turning
EMC Compliance: Tested according to EN 50081-2, EN 50082-2, CE-signed

Model Variants:

DS85-P200: Ranges from 0...50 Pa to 0...200 Pa
DS85-P1000: Ranges from 0...200 Pa to 0...1000 Pa
DS85-P6000: Ranges from 0...2000 Pa to 0...6000 Pa

Error Limits:
Each model has specific error limits for zero deviation, final value deviation, linearity, resolution, and hysteresis, which vary depending on the selected range.

Temperature Drift:

Zero: ± 0.3% per 10 K
Span: ± 0.2% per 10 K

Adjustments:
Zero and final values can be adjusted externally.
