2015 New Arrival WZP PT100 Platinum Resistance RTD Temperature Sensor
RTD Temperature Sensor Probe Dimensions:
Diameter:0.35cm Length:2.9cm Lead Length: About 50cm RTD Temperature Sensor Descriptions: Platinum RTD is an accurate, sensitive, stable temperature sensor. Platinum thermal resistance element is tiny ceramic tubes, holes built around a good system bodiless coil wire platinum RTD temperature sensing element is made, due to the temperature sensing element can be done quite small (the smallest diameter can be ø1.6~ø0.3mm) so it can be made into a variety of micro temperature sensor probe. Can be used within a temperature range of -200 ~ + 420 ℃. WZP series of platinum thermal resistance according to the new standard JB / T8622-1997 production. As the series has a small structure, using a wide range, good reliability, thermal response time is short, etc., can form a multi-species, multi-standard products for the petroleum, chemical, power, metallurgy, light industry, food, textile, medical health, scientific research, agriculture, and machinery industries to provide a new generation of high-quality products. RTD Temperature Sensor Working Principle: Platinum thermal resistance element as a temperature sensor, which works out at a temperature effect, the resistance value of the platinum resistance wire as the temperature changes. The relationship between temperature and resistance is close to a linear relationship, the deviation is extremely small and increase over time, the deviation can be ignored, and stable electrical properties. Note: 1. A grade NA tolerance range for t>650℃ temperature range, and not suitable for two-wire system. 2. Since the heat affected The maximum allowed by platinum resistance measuring current of 5mA, the resulting temperature of not more than 0.3 ℃ 3. Thermal resistance temperature sensing element resistance (R0) at 0 ℃ and its resistance (R100) at 100 ℃, the ratio (R100 / R0) Indexing number Pt100: A grade R0 = 100 ± 0.06 Ω Class B R0 = 100 ± 0.12 Ω W100 = R (100 ℃) / R (0 ℃) = 1.3851
