Signal type and application of temperature sensor

1. What is the temperature sensor

Temperature sensor refers to the sensor that can sense temperature and convert it into usable output signal.

 

2. What are the applications of temperature sensors

The temperature sensor has a wide range of applications, such as temperature measurement and control, temperature compensation, flow rate, flow and wind speed measurement, liquid level indication, temperature measurement, ultraviolet and infrared light measurement, microwave power measurement, etc.

It is widely used in color TV, computer color display, switching power supply, water heater, refrigerator, kitchen equipment, air conditioning, automobile and other fields.

In recent years, the rapid growth of the automotive electronics and consumer electronics industries has led to the rapid growth of the demand for temperature sensors in China.

 

3. What are the types of temperature sensors

The characteristics of sensor materials and electronic components are divided into thermal resistance and thermocouple.

 

 

 

• Thermocouple

MV output can be converted to 4-20mA output. The seven standardized thermocouples S, B, E, K, R, J and T are Chinese unified design thermocouples.

Graduation Mark	Material
	Positive	Negative
S	PT 10	Pure platinum
R	PT 13	Pure platinum
B	PT 30	PT6
K	Ni-Cr	Nickel silicon
T	Cu	Copper nickel
J	Fe	Copper nickel
N	Ni-Cr-Si	Nickel silicon
E	Ni-Cr	Copper nickel

 

• Thermal resistance

Resistance output, commonly used Pt10, Pt100, Pt1000, Cu50 and Cu100.

Pt10 indicates that the resistance value is 10 Ω at 0 ℃.

Our common products are Pt100 and Pt1000.
