Description
Electronics123.COM Inc has released a new version of their KTA-259 Thermocouple Multiplexer Shield, called the KTA-259v4. This shield allows for multiple high temperature readings with an Arduino control board and has several advantages over the previous version, including a wider temperature range, higher accuracy and resolution, and the ability to use more types of thermocouples. The shield features screw terminals for thermocouple connections and can be used in a variety of applications such as automotive, ovens, freezers, and chemical processes. It can also be used for multi-zone temperature monitoring and data acquisition. The shield supports up to 8 thermocouples and has a 14-bit 0.25C resolution with a nominal 2C accuracy. It is based on the MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter and ADG608 Multiplexer IC and also includes a 13 x 8 prototyping area with analog and power pins. The previous versions, KTA-259 and KTB-259, have been discontinued.
The KTA-259v4 Thermocouple Multiplexer Shield is designed to easily allow multiple high temperature readings with an Arduino control board. ith the new version there are multiple advantages over the old KTA-259, namely, wider temperature range including below 0C, higher accuracy, higher resolution and ability to use more thermocouple types (dependent on model). Screw terminals are provided for thermocouple connections as thermocouple wires can not be soldered. Uses: Automotive - Engine, Exhaust and Brake temperatures are higher than most temperature sensors can handle, but within the range of Thermocouples. Ovens, Furnaces and Kilns - At temperatures where other temperature sensors will not operate. Freezer or Cryogenic monitoring - Where temperatures are well below 0C. Chemical Processes - Where corrosive chemicals may damage probes or reach high temperatures thermocouples are more readily available for such processes. Multi-Zone Temperature Monitoring, Data Acquisition or Logging Systems- With cheap readily available thermocouples. [1] This is the range of temperatures that a thermocouple of this type can measure, the Measured Temperature Range is the actual range the KTA-259 can digitize. [2] KTA-259 and KTB-259 are discontinued and are included for reference only. Features: Add up to 8 Thermocouples to an Arduino Cold Junction Compensated Output K, J, N, S, T, E or R Type thermocouples supported dependent on model 0.1" (2.54mm) Pitch Screw Terminals for Thermocouple connection 14-bit 0.25C Resolution Nominal 2C accuracy[1] Based on MAX31855 Cold-Junction Compensated Thermocouple-to-Digital Converter and ADG608 Multiplexer IC 13 x 8 Prototyping Area with Analog and Power pins
