Temperature data acquisition

For universal, fast and precise temperature measurement

Long-term stable temperature measurement

Temperature measurement is of particular importance. It is important that the measurement is precise and reliable. Various factors play a role here, such as choosing the right measuring device, calibration and positioning of the sensor. It is also important that environmental influences are minimized in order to obtain accurate measurement results. Temperatures are measured in almost all applications. Thermocouples or resistance sensors (Pt100(0)) are commonly used. The Delphin products are specially optimized for accurate temperature measurement. Decades of experience are reflected in all Delphin hardware products.

Accurate temperature measurement

The analog inputs of the temperature measurement value acquisition can be universally configured for any thermocouple or resistance sensor in a 4-wire circuit. This is made possible by the use of high-precision and galvanically isolated 24-bit AD converters and precise internal current sources for the reference current supply. There is no need for additional measuring transformers when using Delphin products.

Application highlights of temperature data acquisition

  • High-precision temperature measurement of up to +/- 0.05K
  • Universal inputs for RTDs and any thermocouple type (K, J, B, S, …)
  • Long-term measurement stability with only negligible drift
  • No additional requirement for measurement converters, includes galvanic isolation
  • Stand alone temperature measurement as well as PC-supported operation via LAN or USB

Practical example of temperature data acquisition

Multi-channel temperature measurement at a gas-turbine test stand

On a large turbine test stand, around 3000 temperatures are measured. A range of thermocouple types are being used as well as resistance thermometers for precision measurements. The temperatures are recorded with 64-channel measurement devices from Delphin. The signals are connected using sub-miniature thermo connectors. Measurement data is stored independently within the Delphin devices and simultaneously transmitted via LAN for centralised data recording on a server using ProfiSignal. A total of 12,000 measurement values are recorded at the test stand. Scalable Message devices are used to directly receive temperatures at the point where the sensors are mounted. The devices are calibrated every two years to guarantee measurement precision.

Typical areas of application
of the temperature measurement

  • Acquisition of temperatures in motors, generators, turbines

  • Temperature measurement in chemical and pharmaceutical laboratories
  • Monitoring of room temperatures and climatic data
  • Mobile temperature measurement for start-up procedures
  • Temperature measurements in steelworks
  • High-precision measurements with calibrated Pt100(0) sensors
  • Multi-channel temperature measurement using thermocouples
  • Temperature measurement at test stands
  • Long-term temperature measurement for service-life testing
