The LM26LVEB is an evaluation board, which, combined with LM26LV series sensors, provides designers with evaluation tools that can help evaluate thermoelectric coolers (TECs) to optimize their performance when applied in different applications. This board is designed for use with the LM26LV series of sensing elements or thermistors. It can be used for measuring temperature from -10~85°C and temperature gradients on a surface or within a medium. The sensor and board package has low power consumption, high accuracy, and output linearity around 0.5%.

The major components of the board includes the LM26LVEB TEC module, LM26LV module, temperature measurement unit, controller unit, ULN2003A integrated device and STM32F10x evaluation board. The LM26LVEB TEC module is designed around the LM26LV series sensors and uses a temperature measurement unit to measure the output from the LM26LV01 TEC module. It is then transmitted to the controller unit, which is connected to the ULN2003A integrated device. This device is then connected to the STM32F10x evaluation board for fine-tuning, setting parameters and reading the results.

The working principle behind this board is the use of the LM26LV02 thermal temperature sensing element and LM26LV03 heat intensity sensing element. When energy is applied to the thermoelectric cooler (TEC), the temperature gradient across the element will become larger, which in turn will drive the temperature inside the TEC and increase the output voltage. The LM26LV02 temperature sensing element measures the output voltage from the TEC and converts it into temperature ranges. The LM26LV03 temperature sensing element converts the temperature range into a thermal energy range, which can then be used to understand the power consumption and heat dissipation of the TEC. The board also utilizes a closed-loop control algorithm, which enables it to adjust the output of the TEC according to the user’s requirements.

The LM26LVEB is a great tool for those who are looking to evaluate and optimize thermoelectric cooler performance in various applications. It has a low power consumption, high accuracy and output linearity rating of 0.5%. Its closed-loop control algorithm allows users to adjust the TEC’s output according to user requirements. With its comprehensive integrated components and complete measurement range, the LM26LVEB offers a full evaluation platform for designers who are looking to evaluate and optimize their thermoelectric coolers.
