The difference between transducer and thermocouple sensor

Now on the market can be roughly divided into traditional thermocouple temperature sensor temperature thermocouple sensor and digital temperature thermocouple sensor, the two thermocouple sensors have been widely used. The two thermocouple sensor has the characteristics and application of alone, now also can't say which good which is not good, now also can only say that each has his strong point.

digital thermocouple temperature sensor are different from traditional thermal resistor, using the integrated chip, using single bus technology, it can effectively reduce the interference of the outside world, improve the accuracy of measurement, at the same time, it can be directly measured temperature will be converted to a serial digital signals for computer processing, simple interface, data transmission and process simplification. Part of the function of the circuit integration, make the overall hardware design is more simple, can effectively reduce the cost, set up and welding circuit when faster, more convenient debugging is simple, it shortens the development cycle.

most of the traditional temperature detecting for thermistor thermocouple sensor, using thermistors, measuring range can accommodate 40 degrees Celsius to 90 degrees Celsius, but lower reliability of thermistors, temperature measurement accuracy is low, the signal is not applicable for 1 degrees Celsius, still have to specially the interface circuit is converted into digital signals to the microprocessor for processing.
