Digital station barometer HIM800D with LCD touchscreen, measuring range: 700 to 1100 hPa@±0.0023 hPa

General description
The BPS-800 is a high-precision, ready-to-use air pressure sensor that is specifically designed for
Designed for demanding meteorological applications, the BPS-800 is housed in a robust aluminum casing and equipped with multiple digital interfaces. It delivers precise barometric pressure readings and long-term average data. Thanks to its extremely energy-efficient operating modes and comprehensive protocol support, the BPS-800 integrates seamlessly into weather stations, climate research systems, and environmental monitoring networks.
For enhanced functionality, the BPS-800 can be equipped with an optional 7-inch display.
It can be equipped with a touchscreen display, transforming it into a fully featured station barometer. This advanced configuration offers intuitive local operation, graphical representation of pressure trends, display of historical data, and real-time meteorological information directly on the device. The integrated trend analysis allows users to monitor changes in air pressure and recognize weather developments at a glance, making the system ideal for professional use.
Suitable for weather stations and demanding environmental monitoring applications.
Functionality

Functionality & Data Processing
• Real-time print values available on demand
• Long-term averages are automatically updated every 10 minutes.
• Configuration via USB-C or digital interface (baud rate, parity, slave address, transmission interval)
• Internal FIFO buffering with oversampled accuracy
• All settings are retained after a power outage
• USB-C supports data stream transfer and batch logging to the PC
• Compensation values readable/writable by us
• Support for connecting up to 30 BPS-800 sensors to a single display and monitoring system, enabling distributed pressure measurement networks.
• Expansion options to display additional meteorological parameters such as wind speed, wind direction, temperature and relative humidity. For applications requiring the integration and visualization of multiple sensor types, a dedicated multifunction display should be used instead of the standard BPS-800 display solution.
and control platform will be selected
• The print trend indicator supports an intuitive touchscreen zoom function, with which
Users can freely zoom in and out on historical data. This allows for flexible selection of the displayed time period, from short-term pressure changes to long-term atmospheric trends, and offers detailed analysis tailored to the user's needs.

Typical areas of application
• Weather stations (national, regional, remote)
• Observation stations for environmental and climate research
• Weather measuring instruments for helicopter landing pads and runways
• Mobile measuring and air quality trailers
• Calibration reference for pressure measurements

The BPS-800 is more than a precise pressure sensor – it is a triple-secured measuring instrument. Its compact housing three fully integrated pressure sensors In parallel. Your data is processed, compared and averaged internally to deliver stable, reliable values with high reproducibility – even under extreme conditions.

Advantages of the three-sensor architecture

• Redundancy and plausibility checkInternal cross-checking of the sensor elements protects against measurement deviations.
• Averaging for long-term stability: Counteracts the effects of aging and environmental disturbances.
• Measurement reliability under extreme conditionsIdeal for exposed locations or long-term installations.

Calibrated at the origin of physics

Each BPS-800 is not simply software-based or calibrated to factory standards – but rather on an electronic Mercury barometer, the physical pressure reference system par excellence. In this process 32 individual pressure points per sensor (i.e., 96 measuring points per unit) checked and adjusted.

Other manufacturers save themselves this effort. We define it as standard.

Energy efficiency at the highest level

The BPS-800 was designed for self-sufficient systems:

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

This makes the sensor perfectly suited for:

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

Full connectivity – industrial outputs for every application

The BPS-800 has four digital interfaces, which cover all common industrial protocols. This allows it to be seamlessly integrate into existing systems, whether it's a weather station, environmental monitoring network or mobile research unit.

Available outputs:

1. RS-485
   • Up to 115,200 baud
   • Supported Modbus RTU, Modbus ASCII, ASCII-Stream
   • Ideal for long lines, bus operation, industrial integration

1. RS-232
   • Also up to 115,200 baud
   • Same protocols as RS-485
   • Simple point-to-point communication, for example with data loggers

1. SDI-12
   • Also supports ASCII output
   • Compatible with standard measurement networks

1. USB-C (CDC / Virtual COM-Port)
   • For configuration, live readout
   • Supports data streaming and batch logging on the PC
   • User-friendly, no special interface required.

Other special features:
