Temperature Sensor

A high temp pressure transducer refers to a sensor that can sense temperature
and convert it into a usable output signal. The temperature sensor is the core
part of the temperature measuring instrument, and there are many varieties.
According to the measurement method, it can be divided into two types: contact
type and non-contact type. According to the characteristics of sensor materials
and electronic components, it is divided into two types: thermal resistance and
thermocouple.

Comparison of Temperature Sensor
Thermocouple Temperature Sensor
According to the characteristics of sensor materials and electronic components,
it is divided into two types: thermal resistance and thermocouple.
Thermocouple is the most commonly used temperature sensor in temperature
measurement. The main advantage is that it has a wide temperature range and
adapts to various atmospheric environments, and it is sturdy, low-cost, and
does not require power supply. The thermocouple is composed of two different
metal wires (metal A and metal B) connected at one end. When the thermocouple
is heated at one end, there is a potential difference in the thermocouple
circuit. The measured potential difference can be used to calculate the
temperature.
In short, the thermocouple is the simplest and most versatile temperature
sensor, but the thermocouple is not suitable for high-precision measurement and
application.

Thermal resistance Temperature Sensor
Thermistors are made of semiconductor materials, most of which have a negative
temperature coefficient, that is, the resistance decreases with increasing
temperature. Temperature changes will cause large resistance changes, so it is
the most sensitive temperature sensor.
Thermistors also have their own measurement techniques. The thermistor's small
size is an advantage, it can be quickly stabilized without causing thermal
load. However, it is also not very strong, and large currents will cause self-
heating. Because the thermistor is a resistive device, any current source will
cause heat on it due to power. The power is equal to the product of the current
squared and the resistance. Therefore, use a small current source. If the
thermistor is exposed to high heat, it will cause permanent damage.
