A spring at the sensor’s tip is fastened to a rod, which extends up to the gauge needle. In the stems’ sensing ends, the spring is located.
The temperature is displayed when heat is introduced to the detecting coil, which causes movement in the coil to move the gauge’s needle.
The Global analog temperature sensors market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Texas Instruments LMT70 is a CMOS analogue temperature sensor that is incredibly compact, highly accurate, and low power with an output enable pin.
The LMT70 has a wide range of temperature sensing applications, including Internet of Things (IoT) sensor nodes, high-precision instrumentation, battery-powered devices, and nearly any sort of temperature sensing where cost-effectiveness, high precision, and low power are required.
RTD and precise NTC/PTC thermistors are both excellent candidates for replacement by the LMT70. Multiple LMT70s can share a single ADC channel thanks to its output enable pin, simplifying ADC calibration and lowering the total system cost for precise temperature detection.
Additionally, the LMT70 provides a linear and low impedance output that enables a seamless link to a commercially available MCUIADC.
The LMT70 has extremely low self-heating, supporting its high precision over a wide temperature range, and dissipates less than 36 W.
For two adjacent LMT70As selected from the same tape and reel, the LMT70A offers unmatched temperature matching performance of 0.1°C (max). The LMT70A is a perfect option for energy metering applications that need to calculate heat transfer.
