BPS-1000 – Barometric Pressure Sensor with Triple Precision

---

Absolute Accuracy – Triple Safeguarded

The BPS-1000 is more than a precision pressure sensor – it is a triple-redundant measurement instrument. Inside its compact housing, three fully integrated pressure sensors operate in parallel. Their data is processed, cross-checked, and averaged internally to provide stable, reliable measurements with exceptional repeatability, even under extreme environmental conditions.

Advantages of the Triple-Sensor Architecture

• Redundancy and plausibility verification: Internal cross-checking of sensor elements protects against measurement deviations.
• Averaging for long-term stability: Compensates for aging effects and environmental disturbances.
• Reliable operation under extreme conditions: Ideal for exposed locations and long-term installations.

Calibrated at the Origin of Physics

Every BPS-1000 is not merely calibrated through software or factory standards; it is calibrated against an electronic mercury barometer, one of the most fundamental physical pressure reference systems available.

During calibration, 32 individual pressure points per sensor (a total of 96 measurement points per unit) are verified and adjusted to ensure outstanding accuracy and consistency.

Outstanding Energy Efficiency

The BPS-1000 has been designed specifically for autonomous and low-power systems:

• < 20 µA in sleep mode
• 3 mA during continuous active measurement
• Dynamic power-saving functions automatically detect the operating mode (polling vs. streaming)

This makes the sensor ideal for:

• Solar-powered weather stations
• Environmental monitoring systems in the field
• Battery-powered long-term applications

Available Interfaces

RS-485

• Up to 115,200 baud
• Supports Modbus RTU, Modbus ASCII, and ASCII Stream
• Ideal for long cable runs, multi-drop bus systems, and industrial automation

USB-C (CDC / Virtual COM Port)

• Configuration and live data readout
• Supports data streaming and batch logging on a PC
• User-friendly operation without specialized hardware interfaces

Part of an Intelligent DIN-Rail System

The BPS-1000 is fully compatible with the modular DIN-rail ecosystem. Sensors and modules connect directly via the DIN rail and can share both power and communication through the system bus architecture.

This significantly reduces wiring complexity. Installations become faster, cleaner, and far more space-efficient. Additional modules can be added at any time without extensive modifications to existing wiring.

Your Benefits

• Reduced wiring effort
• Faster installation
• Space savings inside control cabinets
• Modular expandability
• Centralized bus communication
• Increased system reliability

Designed for Professional Applications

Additional protection and convenience features make the BPS-1000 the ideal solution for long-term field deployment:

• ESD protection up to 15 kV on all data interfaces
• Freely configurable output intervals from 1 second to 24 hours
• Permanent storage of all settings
• Continuous ASCII streaming mode for real-time data
• Rugged design for continuous operation and outdoor environments

More Performance for Less Cost

Despite its exceptional accuracy, extensive multi-point calibration, and triple-sensor architecture, the BPS-1000 offers an outstanding price-to-performance ratio.

It combines professional-grade measurement technology with an economically attractive platform suitable for volume production, scientific research, environmental monitoring, and industrial systems.
