Transmit sensor data without cables

SECU DATA wireless systems transmit measurement signals up to 1.5 km via 433 MHz radio, including ATEX-certified variants for hazardous areas.

Eliminate costly cable runs and ground loop issues. SECU DATA transmits 4-20mA signals, relay contacts, Namur signals, TRbF signals, and RS232 data wirelessly between Ex and non-Ex areas.

Cable runs are expensive and create ground loop risks

Running signal cables across industrial sites requires excavation, conduit installation, and ongoing maintenance. Ground loops between distant points corrupt measurement signals and create safety hazards in Ex areas.

  • Excavation and conduit installation costs for long cable runs
  • Ground loops causing measurement errors and interference
  • Cable damage from construction, vehicles, or corrosion

Signal loss means blind spots in process monitoring

When measurement signals fail to reach the control room, operators lose visibility of critical process parameters. In hazardous areas, this can lead to undetected overfills, leaks, or equipment failures.

Reliable wireless links without galvanic connection

SECU DATA provides galvanic isolation between transmitter and receiver, eliminating ground loops. Quick installation without excavation, and proven reliability in industrial environments.

Industrial 433 MHz wireless transmission

SECU DATA uses the license-free 433 MHz band with special barriers for safe operation in Ex Zone 1.

  1. 1

    Signal input and conditioning

    SECU DATA accepts 4-20mA analog signals, relay contacts, Namur signals, TRbF signals, and RS232 data from process sensors and instruments.

  2. 2

    433 MHz radio transmission

    Data is transmitted via 433 MHz radio with ranges up to 1.5 km. Special barriers with high current yield and stable output voltage enable Ex Zone 1 applications.

  3. 3

    Receiver output to control systems

    The receiver regenerates the original signal format for connection to PLCs, SCADA systems, or local displays without ground loop interference.
