Application industry
Overview: The HTDC series battery powered temperature display device is a new generation of advanced on-site transmission unit launched by our company. This transmitter adopts advanced low-power CPU and large screen LCD display, powered by lithium battery, no need for external power supply, long service life, and no maintenance cost. Using aluminum alloy casing, imported high-precision platinum resistance sensors orthermocoupleSensors, corrosion-resistant, overload resistant, stable, high precision, with a resolution of up to 0.1 ℃, can be applied to various corrosive and non corrosive liquid and gas measurements in petroleum, chemical, coal, defense departments, and non power supply environments.
Working principle
The instrument converts the temperature signal into an electrical signal through a temperature sensor, which is then amplified and filtered by a preamplifier before being sent to the A/D conversion module of the CPU for analog-to-digital conversion. Finally, the data is processed and displayed by the CPU.
