We offer several different models of thermocouple data acquisition systems that are suitable for the measurement of temperature. A key feature of these systems is the flexibility to monitor other parameters in addition to temperature which makes them suitable for applications such as equipment test stands, component test, QA and reliability testing and R&D testing. An important factor to consider in selecting a data acquisition system for temperature monitoring using thermocouples is the ability of the system to provide accurate measurements. Because thermocouples provide a very small, non-linear voltage output and this output is a relative measurement it imposes some additional requirements on the system:
- Low voltage measurements capability with microvolt accuracy
- Accurate cold junction compensation at the point where the thermocouples are terminated at the system
- Conversion tables using ITS polynomials
- Measurement filters to reduce the effect of EMI and RFI noise in the environment
These systems also provide basic voltage/current inputs, digital I/O, counters/frequency inputs and more.
