Sensor Termocupla J Salida Digital Max31855 Soic8 Itytarg

Modelo solo para termocupla J

General Description

The MAX31855 performs cold-junction compensation

and digitizes the signal from a K-, J-, N-, T-, S-, R-, or

E-type thermocouple. The data is output in a signed

14-bit, SPI-compatible, read-only format. This converter

resolves temperatures to 0.25°C, allows readings as

high as +1800°C and as low as -270°C, and exhibits

thermocouple accuracy of ±2°C for temperatures ranging

from -200°C to +700°C for K-type thermocouples. For full

range accuracies and other thermocouple types, see the

Thermal Characteristics specifications.
