SECU DATA is a wireless measurement data transmission system, which was developed for industrial purposes especially for use in potentially explosive atmospheres. The data can be transferred from the EX area to another area (EX or non-EX). Range is up to 1.5 km.

The products of the SECU-DATA series use the latest technologies for the transmission of measurement data via radio links in the 433 MHz band for a wide range of applications: Wireless data transmission of

  • 4-20 mA signals
  • Relay contact states
  • Namur signals
  • TRbF signals
  • RS232

Typical applications include process monitoring, process automation in the industry, evaluation of various sensors for temperature, humidity, level in the chemical industry, remote monitoring of all sensors with analog output and 4-20 mA interface, as they are often used in process technology or level indicator. systems.

Special "barriers" with high current efficiency and stable output voltage allow applications in hazardous areas, in zone 1.


  • Measurement data transmission from potentially explosive areas to safe areas without galvanic connection.
  • No cabling, ground loops excluded.
  • Fast installation without pruning and digging work
  • Highest reliability
  • Transmission range (up to 1.5 km)
  • certification: ATEX certificate:
  • TÜV-A 06ATEX0008X classification: II 2 G Ex i(a)b IIC T4 "

SECU DATA – Wireless Data Transfer in the Construction Industry

In this project, which Secu-Tech has realised with one of the leading Austrian Construction Companies, the measurement data readings of an inductive flow meter are transfered wireless via the SECU-DATA transmitter to the SECU-DATA receiver on a drilling device.  These measuring data are recorded and evaluated in the drilling device by means of a measurement data acquisition system.

The big advantage using SECU-DATA wireless data transfer is the weakness of cables laying on the ground of a big construction area which are prone to defect because of the rough conditiions and traffic. This cause problems and costs. Wireless is the best solution in these applicational areas.

The SECU-DATA transmitters and receivers can be transfered from construction area to construction area, from application to application or used for mobile applications. The devices are robust and built to be used outside under rough conditions. The SECU-DATA wireless data transfer devices are also availabe for ATEX areas.

SECU DATA – Wireless Data Transfer – Level Gauging in Chemical Industry

In this project with an Austrian Chemical Company the level is measured by means of a radar sensor, which has a 4-20 mA interface. These signals are taken over by SECU DATA at the level gauge measurement point and are sent 1:1 to the SECU DATA Control device, which is placed around 500 m from the measurement point. Connected is an indicator device which shows the liters in the tank. From there, high/low level alarms are sent to the operator via SMS.
