PT100 Thermistor Product Introduction
PT100 thermistor is a high-precision temperature sensor made of platinum as the core material. It is named after the standard resistance value of 100 Ω at 0 ℃ and is an ideal choice for low-temperature temperature measurement in industrial and scientific research fields.
Excellent performance, precise temperature measurement
The PT100 thermistor relies on the excellent temperature resistance characteristics of platinum metal to achieve wide range and high-precision temperature measurement. Its temperature measurement range covers -200 ℃ to 850 ℃, with an accuracy of ± 0.1 ℃ and excellent linearity. It can stably output accurate data in complex environments. Within the temperature range of 0 ℃ to 100 ℃, the resistance value increases approximately uniformly with temperature. At 100 ℃, the resistance value is about 138.5 Ω. This stable variation pattern provides a reliable basis for temperature detection.
Diversified wiring, adaptable to different scenarios
For different application scenarios, PT100 thermistor offers three wiring methods: two-wire, three wire, and four wire. The two-wire system has simple wiring and is suitable for short distances with low precision requirements; The three wire system effectively eliminates measurement errors caused by lead resistance through the principle of bridge compensation, and is the mainstream choice in industrial process control; The four wire system adopts constant current source excitation and high impedance detection technology, which can completely eliminate the influence of lead resistance and meet the high-precision temperature measurement requirements at the laboratory level.
Widely used and reliably guaranteed
With its advantages of high precision, high stability, and strong anti-interference ability, PT100 thermistor has a wide range of applications. In industrial automation, it is commonly used for temperature monitoring of chemical reaction vessels and electrical equipment; In the medical field, it can accurately monitor the temperature of equipment such as hemodialysis machines; In the new energy vehicle industry, provide data support for battery management systems and motor temperature control. In addition, it can also be adapted to temperature isolation transmitters to achieve signal isolation transmission and distortion free remote transmission, perfectly integrating with industrial control systems such as PLC and DCS, providing solid support for temperature monitoring and control in various scenarios.
