BPS-800 – Barometric Pressure Sensor

---

Absolute Accuracy – Triple Verified

The BPS-800 is more than just a barometric pressure sensor – it’s a triple-redundant electronic barometer .
Housed in a compact enclosure, three fully integrated pressure sensing elements operate in parallel. Their data is internally processed, cross-validated, and averaged to deliver stable, reliable readings with high reproducibility – even under extreme environmental conditions.

Advantages of the Triple-Sensor Architecture

• Redundancy and plausibility checks: Internal cross-verification of sensor data protects against measurement deviations.
• Averaging for long-term stability: Compensates for aging effects and environmental interference.
• Measurement reliability in extreme conditions: Ideal for exposed locations or long-term installations.

Calibrated at the Origin of Physics

Each BPS-800 is not simply software-corrected or factory-standard aligned – it is calibrated using an electronic mercury barometer, the gold standard of physical pressure reference systems.
A total of 32 individual pressure points per sensor (96 per unit) are checked and adjusted.

Where other manufacturers cut corners, we define this level of calibration as our standard.

Top-Level Energy Efficiency

The BPS-800 is designed for autonomous systems:

• <20 µA in sleep mode
• 3 mA during continuous measurement
• Dynamic power-saving modes automatically detect operation type (polling vs. streaming)

This makes the sensor ideal for:

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

Full Connectivity – Industrial Interfaces for Every Application

The BPS-800 includes four digital interfaces that support all common industrial protocols.
This ensures seamless integration into existing systems – whether in weather stations, environmental monitoring networks, or mobile research platforms.

Available Interfaces:

• RS-485
  Up to 115,200 baud
  Supports Modbus RTU, Modbus ASCII, and ASCII stream
  Ideal for long cable runs, bus systems, and industrial use
• RS-232
  Also up to 115,200 baud
  Same protocols as RS-485
  Simple point-to-point communication, e.g. with data loggers
• SDI-12
  Also supports ASCII output
  Compatible with standard environmental networks
• USB-C (CDC / Virtual COM Port)
  For configuration and live readout
  Supports data streaming and batch logging to a PC
  User-friendly – no special interface required

Additional Features

• ESD protection up to 15 kV on all data lines – perfect for field deployment
• Customizable output intervals: from 1 second to 24 hours
• Persistent settings – all configurations remain saved even after power loss
• ASCII streaming mode: continuous data output – ideal for live data capture
