There are two differences in the working principle of the blood glucose meter, one is photoelectric type, and the other is electrode type. Photoelectric blood glucose meters belong to the traditional blood glucose meter, and its price is rel....
More than 1 million women worldwide are diagnosed with breast cancer every year, and nearly 40% of them die as a result. However, if breast cancer patients can be detected and treated at an early stage (no lymph node involvement), the cure r....
First of all, we will learn about the thermal printing head. Thermal printing head (TPH) can be divided into thin film thermal printing head and thick film thermal printing head according to different manufacturing processes. The thin film t....
The self-recovery fuse is a new type of fuse with overcurrent and overheat protection that can be reused multiple times. 1. The structural principle of self-recovery fuse: Self-recovery fuses are PTC thermal elements with positive temperatur....
Abstract: This paper presents the hardware and software design of multi-channel PT100-III signal conversion module. Key words: three-wire system; PT100; MODBUS introduction PT100 is a widely used temperature measuring element. It has unparal....
Summary: This paper introduces a method for accurately measuring the resistance of three-wire thermal resistance by constant voltage partial pressure method. For Pt100 thermal resistance, the detection resolution can reach 0.005W. At the sam....
Three conventional applications for thermistors: surge absorption, temperature measurement, and temperature compensation. NTC Thermistor It is a negative temperature coefficient thermistor. The resistance decreases with the increase of tempe....
In the field of NTC thermistors, there are currently two insufficient NTC thermistors and single-ended glass-sealed thermistors on the market. Among them, single-ended glass-sealed NTC thermistors are mostly insulated through insulated bushi....
What is the significance of linearity? Linearity is the degree of linearity that describes the output voltage of the sensor varies with temperature . In fact, it is the maximum deviation of the sensor output voltage from the ideal fit line....
