PT100溫度感測器 防腐防水型高溫鉑熱電阻電偶 高精度 2B級（0.5米線）精度0.5  耐高溫 防水 防油 防腐 防酸 不鏽鋼 316封裝 4x30mm

對於精確的溫度感測，鉑金RTD溫度傳感器PT100無與倫比。電阻溫度檢測器（RTD）是一種溫度傳感器，包含一個隨溫度變化而改變電阻值的電阻，基本上是一種熱敏電阻。在此傳感器中，電阻器實際上是一小條鉑金帶，在0°C時的電阻為100歐姆，因此命名為PT100。與大多數NTC / PTC熱敏電阻相比，PT類型的RTD最穩定，最精確（但價格也更高）PT100已在實驗室和工業過程中用於測量溫度多年，並在精度方面享有盛譽（更好）比熱電偶），重複性和穩定性高。

這款高溫PT100傳感器配備了不銹鋼屏蔽罩，適用於最高550°C的溫度。

PT100溫度感測器：

• 基於電阻測量原理
• 電阻器材料為鉑，在0°C溫度下的電阻值為100 ohm
• 鉑具有正電阻溫度係數；電阻隨溫度升高而增加
• 電阻變化是溫度的函數：標稱值為0.385Ω/°C
• 與熱電偶，基於矽的溫度傳感器或熱敏電阻相比，具有更高的精度和穩定性

每個傳感器帶有三根電線。如您所願，兩條線連接到鉑電阻的任一側。所述第三導線也連接到PT100的一端。如果您的RTD放大器支持3線製傳感器，它將使用前兩根線驅動電阻器，並測量電壓差，以便可以從線中減去任何電壓降。如果您的RTD放大器僅支持2線製，則只需斷開第三條線的連接即可。

Platinum RTD Temperature Sensor PT100 – 3 Wire 1 Meter

Platinum RTD Temperature Sensor PT100 – 3 Wire 1 Meter

For precision temperature sensing, nothing beats a Platinum RTD Temperature Sensor PT100. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive) PT100’s have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.

This high-temperature PT100 sensor is equipped with an stainless steel shield is good for up to 550°C.

PT100 features:

• Based on resistance measurement principles
• Resistor material is Platinum with a value of 100 ohm at temperature 0°C
• Platinum has a positive resistance temperature factor; resistance increases with rising temperature
• Resistance variation is a function of temperature: 0.385Ω/°C nominal
• High accuracy and stability compared to thermocouples, silicon-based temperature sensors, or thermistors

Each sensor comes with three wires. Two of the wires connect to either side of the platinum resistor like you’d expect. The third wire is also connected to one end of the PT100. If your RTD amplifier supports 3-wire sensors, it will drive the resistor with the first two wires, and measure the voltage differences so that it can subtract any voltage drop from the wires. If your RTD amplifier only has 2-wire support simply leave the third wire disconnected.
