The Anville Series 825 TVI (Thermal Validation Interface) is designed for use with EaziVal SE software. Anville's thermal validation systems can be used wherever it is necessary to maintain a formal record to prove that the correct temperatures and pressures have been achieved during a critical process.

The Anville Series 825 TVI differs from the majority of data loggers by the design of the thermocouple input connection, associated thermocouple cold junction compensation and in the use of analogue input parallel processing enabling the unit to have an acquisition rate of better than once per second for all inputs. The Series 825 TVU uses individual high-speed amplification and analogue to digital conversion on each input channel with conversion to engineering units (°C/°F) carried out by the internal microcontroller. Data is communicated to the computer in the correct engineering units enabling the system to have a traceable calibration certificate. The Series 825 TVI has an internal power supply to provide a 20VDC excitation voltage for the 4-20mA inputs and no separate power supply is required for a loop powered transducer.

In the Anville Series 825 TVI all cold junction compensation errors are minimised by using correctly compensated miniature type T thermocouple connectors with matching class 1 thermocouple wiring to the internal cold junction sensor. A 1/3 DIN PT100 sensor measures the cold junction temperature to an accuracy of ±0.1°C at 0°C. Design of the physical layout of the cold junction reduces any thermal scatter to a typical deviation of ±0.05°C.

The Anville Series 825 measurement range for type T thermocouples is -200°C to 300°C with a resolution of 0.01°C. Over a measurement range from -50°C to 300°C the overall system accuracy is ±0.25°C. This accuracy is maintained over an ambient operating temperature range from 0°C to 50°C and includes all errors due to thermocouple cold junction compensation, DC amplification, A/D conversion and thermocouple linearisation.

The Series 825 TVI accuracy of ±0.25°C is the worst case "out of the box" value including all system errors but excluding thermocouple sensor error.
