Hello, i'm ts118-3 infrared temperator department, zhang ji。
Ts118-3 infrared temperature sensors are used for temperature measurements in medical and industrial markets. These data are essential for applications ranging from vital signs monitoring of patients to monitoring the state of critical industrial machinery. The ts118-3 sensor detects infrared energy from objects a few inches to a few feet away, thus providing a convenient and reliable measure. Infrared heat reactors can measure the temperature from -40°c to 300°c wide. Using rtd or ntc-based high-precision reference sensors, ts118-3 is more easily compensated and provides temperature output。
Non-contact temperature sensors:
As non-exposure temperature sensors do not have direct contact with the detected medium, some physical properties of the exposure medium need not be considered. In addition, non-contact temperature sensors are subject to space limitations. Remote temperature measurements can be performed for a number of detected objects that are remote and difficult to reach。
Thermal electromechanism:
When two different conductors form circuits with semiconductors a, b, and the two ends are interconnected, the temperature at one end is t, i. E. The working end or the heat end, and the temperature at the other end is to, i. E. The free end or the cold end, and there is a current in the circuit, i. E. The electrical dynamic that exists in the circuit, which is called the heat-electric dynamics. This phenomenon of electric motion due to temperature differences is known as the sebek effect. (b) second, when the current passes through a conductor with a temperature gradient, the conductor absorbs or releases the heat (depending on the direction of the current relative to the temperature gradient), known as the tomson effect. The combination of two different conductors or semiconductors is called thermoelectric dolls。
Temperature method: the conductor of two different components (known as thermal voltage or thermal electrodes) is connected to a circuit. When the heat is at different times, there's electricity in the circuit. This phenomenon is called thermal power effect. And it's called thermal. The thermoelectric dolls use this principle to measure temperature. The working end (also referred to as the measurement end) and the cold end (also referred to as the compensatory end) are used directly to measure the temperature of the medium; the cold end is connected to the monitor the meters that show thermal dynamics generated by the thermoelectric dolls, and the temperature of the detected medium can be obtained by searching for the thermoelectric counter. When the thermoelectric dolls are heated at one end, there is a bit difference in the thermoelectric doll circuit. Temperatures can be calculated from measured level differences。
Thermally sensitive electrical resistance sensors:
The electrical resistance values of the vector vary with the temperature, and the temperature of the object measured by measuring the resistance values. The sensor formed in this way is the resistance temperature sensor, which is used primarily for temperatures within the temperature range -200-500°c. Measurement. Pure metals are the main building materials for heat and electrical resistance. Thermal resistance material shall have the following characteristics: the resistance temperature coefficient shall be large and stable, and the resistance value shall have a good linear relationship with the temperature; the resistance rate shall be high and the heat capacity small。
Temperature method: thermal resistance measures the temperature based on the heat effect of the resistance, i. E. The resistance value of the resistance varies with the temperature. Therefore, temperature can be measured as long as the temperature resistance changes are measured。
