The LM86CIMX is a temperature sensing system temperature sensor designed with a wide range of application field and working principle.

The LM86CIMX is primarily used for sensing temperature of various media in industrial and laboratory environments such as water, coolants, gases and liquids. It is designed to operate with either DC voltage or AC current and supports temperature sensing over a range from -50 to +250°C.

The sensor features an analog output, which is typically connected to a display or other instrumentation to indicate the measured temperature. The analog output is available in two main ranges namely 0 to 5V and –5 to +5V, with ±0.3% of full scale accuracy. A digital output is also available for direct interfacing to a microprocessor-based system. The digital output is available in current loop or voltage output types.

The LM86CIMX employs a variety of operating principles including direct dialometer working in conjunction with an active bridge circuit, and thermocouple sensing with thermistor compensation. Depending upon the application, the LM86CIMX may also be configured as a ‘one-wire’ device allowing seamless data transmission without the need for any external circuitry for power or signal conditioning.

The LM86CIMX can be configured to run based on two main measurement principles. The first is direct measurement of resistance of the temperature sensing element known as the direct-dialometer principle. Here the temperature is sensed using a resistive thermistor flower bridge. The other principle employed is the thermocouple principle, in which the temperature is sensed via a thermocouple element connected to an active bridge circuit.

The thermistor flower bridge, when balanced, provides an accurate output voltage proportionate to the temperature being measured. The active bridge method employs an amplifier to amplify the thermocouple voltage and provides a direct voltage output.

The LM86CIMX has been designed with the specific objective of reducing the amount of wiring required for installation. This is particularly useful for large scale installations or where multiple probes need to be connected. The LM86CIMX is also equipped with a built-in error checking facility, which ensures accuracy and reliability of the information provided to the connected system.

The LM86CIMX is housed in a robust ABS case and is equipped with an integral mounting bracket for secure installation. The device also has a waterproof and dustproof design, making it suitable for use in harsh environments. The LM86CIMX is designed for use within the range of -50 to 200°C without any adjustment, making it ideal for embedded and outdoor systems.

The LM86CIMX temperature sensors are a highly reliable and accurate solution for industrial and laboratory temperature measurements. The device offers a highly accurate output, with a ±0.3% of full scale accuracy, along with the simplicity of direct wiring or one-wire configuration. Its robust construction and compact size make it suitable for use in harsh environments. Therefore, LM86CIMX can be a great choice for reliable and accurate temperature measurements in industrial and laboratory applications.
