The data logger PT-104 is a high-resolution four-channel temperature converter for PT100 and PT1000 platinum resistance thermometers (PRTs). It can be used to measure temperature, resistance and voltage.
In the operating modes PT100, PT1000 and resistance measurement, the device can use a two, three or four wire circuit. The highest accuracy is achieved with the four-wire measurement. By using a high-performance 24-bit ADC, a resolution of around 0.001 ° C is achieved.
In voltage mode, the input connection can be used as a differential input with earth or as two asymmetrical inputs. Two voltage ranges are available (0 to 115 mV or 2.5 V). The data logger PT-104 can be operated via USB as well as via Ethernet (Power-over-Ethernet (PoE)) and can be supplied with voltage.
