Accuracy and resolution
Although accurate temperature sensors are widely available, it has been difficult to take advantage of them due to errors caused by the measuring device. Your PT-104, however, is inherently accurate due to its innovative design. Rather than relying on voltage references, which tend to be temperature-sensitive, it uses reference resistors, which are extremely stable with low temperature coefficient and drift. The exact value of each resistor is stored in an EEPROM to provide the ultimate in accuracy (yearly recalibration is recommended). A high-performance 24-bit ADC is used to achieve the 0.001 °C resolution.
Temperature
The PT-104 measures temperature using platinum resistance thermometers (PRTs). Both common industry standards (PT100 and PT1000) are supported. The unit is compatible with two, three and four-wire sensors (four-wire PT100 sensors are recommended for accurate measurements). A wide range of PT100 sensors are available for use with your PT-104.
