　　What temperature sensors are commonly used for lab water chiller?

　　Generally speaking, the temperature sensors used in laboratory chillers mainly include the following types:

　　1. Thermocouple

　　Thermocouples are sensors that convert temperature into electrical signals. It consists of two metal wires of different materials, connected to each other at both ends to form a loop. When their connection is affected by temperature, the thermocouple can generate a voltage signal to measure temperature. In chillers, thermocouples are typically used for measurements in high temperature ranges.

　　2. Thermistor

　　Thermistors are also sensors that convert temperature into electrical signals. It is composed of a resistive material, and when it is affected by temperature, its resistance value will change, generating a voltage signal to measure temperature. In laboratory chillers, thermistors are typically used for measurements in the medium to low temperature range.

　　3. Infrared thermometer

　　The Infrared thermometer can measure the surface temperature of objects through infrared ray. This type of sensor does not require contact with objects, thus avoiding pollution and pollution issues. In laboratory water chillers, Infrared thermometer are usually used to measure the temperature of hard to contact surfaces (such as pipes, water tanks, cooling towers, etc.).

　　4. Thermoelectric Bao

　　Thermoelectric Bao is a sensor that can convert temperature into electrical signals. It is composed of a conductive material, and when it is affected by temperature, its resistance value will change, generating a voltage signal to measure temperature. In chillers, thermoelectric Baotong is commonly used for measurement in the medium to high temperature range.

　　To sum up, the temperature sensors used in the laboratory water chillers include thermocouples, thermistors, Infrared thermometer and Thermo Power. Each type of sensor has its advantages and limitations, and the appropriate sensor should be selected based on the specific situation. By correctly using and maintaining temperature sensors, it can be ensured that the laboratory chiller is always in a safe, reliable, and efficient state.
