This circuit uses the ADuCM360 precision analog microcontroller in an accurate thermocouple temperature monitoring application and controls the 4 mA to 20 mA output current accordingly. The ADuCM360 integrates dual 24-bit sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), dual programmable current sources, a 12-bit digital-to-analog converter (DAC), and a 1.2 V internal reference, as well as …

The MCP9600 Evaluation Board is used to digitize the Thermocouple EMF voltage to degree Celsius with +/-1C accuracy. Users can easily evaluate the all device features using a Type K thermocouple. The device also supports Types J, T, N, E, B, S and R. Each of these types are evaluated by replacing the Type K Thermocouple connector with the corresponding connectors (not included).

The SHT31 Smart Gadget is a reference design circuit board which demonstrates the outstanding performance and ease of use of Sensirion's humidity and temperature sensors.

The circuit on EVAL-CN0337-PMDZ is a completely isolated 12-bit, 300 kSPS RTD temperature measuring system that uses only three active devices.

The MAXREFDES42# is a high-accuracy IO-Link® resistance temperature detector (RTD) temperature sensor reference design for use with a 2-wire, 3-wire, or 4-wire PT100 RTD over a wide temperature range. Built in an industrial form factor, the design makes use of Maxim Integrated’s highly integrated MAX31865 RTD-to-digital converter.

The MAX31865 evaluation kit (EV kit) provides the hardware and software (graphical user interface) necessary to evaluate the MAX31865 RTD-to-digital Converter. The EV kit includes a MAX31865ATP+ installed as well as a USB-to-SPI interface. The USB-to-SPI master section of the EV kit can be used to interact with the MAX31865 EV kit software and exercise the device’s functionality.

In general, for portable 2-wire 4 to 20mA current loop applications, the system power consumption needs to be considered carefully. The conventional approach of using a high bridge excitation voltage and an operational amplifier to achieve a full-scale ADC input voltage increases chip count and overall power consumption. An additional external voltage regulator is also needed to excite the bridge…

The PT100 RTD Evaluation Board demonstrates how to bias a Resistive Temperature Detector (RTD) and accurately measure temperature. Up to two RTDs can be connected. The RTDs are biased using constant current source and the output voltage is scaled using a difference amplifier. In addition to the difference amplifier, a multiple input channel Programmable Gain Amplifier (PGA) MCP6S26 is used to dig…
