Digital precision air pressure sensor HIM800, measuring range: 400 to 1200 hPa

Absolute accuracy – triple-secured

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:

• ESD protection up to 15 kV on all data lines – ideal for field applications
• Output intervals freely selectable: 1 second to 24 hours
• All settings persist: remain even after power loss
• ASCII streaming modeSensor data is continuously transmitted – perfect for live data acquisition.
