DatasheetThe DPS5000 SDI-12 by Druck is a next-generation digital pressure sensor from the UNIK5000 family, combining the proven reliability of piezoresistive technology with intelligent digital output. Designed for high-accuracy pressure and temperature measurements, it communicates directly via the SDI-12 protocol (v1.4), making it ideal for environmental monitoring, level measurement, and industrial automation.
Key Features at a Glance:
- Pressure ranges: 350 mbar to 70 bar (gauge, absolute, or barometric)
- Total accuracy: up to ±0.1% full scale (FS) over the compensated temperature range
- Fully digital communication via SDI-12 protocol (v1.4)
- Long-term stability: ±0.05% FS/year typical
- Housing options: Stainless steel 316L or titanium
- Temperature range: –40 °C to +80 °C
- Configurable: filter settings, units, outputs and connections
- Ingress protection: up to IP68 depending on cable type
- Media compatibility: suitable for aggressive fluids (e.g. with Hastelloy C276)
- Low power consumption: < 10 mA operation, < 50 µA standby
Typical Applications:
- Groundwater and environmental monitoring
- Level measurement in wells, rivers, and tanks
- Barometric pressure measurement
- Industrial process monitoring
- OEM integration with SDI-12 data acquisition systems
