Charge gun temperature sensor PT1000

Pt1000 is a platinum RTD, made of platinum, positive temperature coefficient, its resistance value will change with the change of temperature. PT1000 "1000" that is to say that it is at 0 ℃ resistance value of 1000 ohms, at 300 ℃ its resistance value of about 2120.515 ohms.

Working Principle: When PT1000 is at 0 degree Celsius, it has a resistance value of 1000 ohms, and its resistance value changes linearly with temperature.

PT1000 thermal resistance value calculation

R(t) = R0 (1 + At + Bt2)

R (t) is the resistance value of platinum RTD when the temperature is t, Ω; (t) is the temperature, ℃; R0 is the resistance value of platinum RTD when the temperature is 0 ℃, Ω; A, B is the indexing constant. Indexing constant A = 0.0038623139728 ,B = -0.00000065314932626

PT1000 Thick Film Platinum Resistors Temperature Sensor The resistance value of PT1000 thick film platinum resistance temperature sensor deviates from the tolerance of the given index table by no more than ±(0.30+0.005∣t∣)*Note: ∣t∣ is the absolute value of the measured temperature (℃); PT1000 thick film platinum resistance temperature sensor is allowed to pass through the working current of ≦0.5mA.

 What is the difference between Pt1000 and Ni1000?

First, Pt1000 is a platinum RTD, made of platinum, positive temperature coefficient, its resistance value will change with the temperature.

 In the modern industrial production process is very widely used, industrial requirements for high temperature stability of the occasion, we are recommended to use the Pt1000 temperature sensor, Pt1000 resistance value is 1000 ohms said 0 degrees C. Pt1000 is made of high purity platinum resistance conductor, has a very good linearity, high temperature stability and reproducibility.

Second, Ni1000 is a nickel RTD, made of high purity nickel, also positive temperature coefficient, resistance value of 1000 ohms 0 degrees Celsius, the price is cheaper than PT1000, the stability is not as good as PT1000, the application is relatively less.
