The temperature converter in DIN/B head size converts the signal obtained from temperature probes of Pt100, Ni100, Pt1000 type, thermocouples K, S, R, J, T, N, B, E, voltage -10...70mV and resistance 0...400? / 0...4k? into a normalized current signal 4...20mA. The characteristics of these transmitters ensure high accuracy of temperature reading due to 16-bit precision A/D converter. At the same time, this solution allows you to change the scale for the output signal, adjust the linearization or perhaps adjust the filter strength of the input value.
Programming is done via RFid wireless technology (NFC) using an NFC-enabled mobile phone or the separately supplied programmer , which allows the operator to quickly perform all necessary calibrations and adjustments with the benefits of galvanic isolation thanks to wireless transmission technology. An app is available for Android mobile devices with NFC capability that allows you to program, adjust and view data in the field.
Non-volatile memory allows data logging with adjustable sampling frequency. Programming software (downloadable from the manufacturer's website) allows this data to be processed and the temperature curve to be displayed.
