# What is the resistance of PT100?

## What is the resistance of PT100?

The most common type (PT100) has a resistance of 100 ohms at 0 °C and 138.4 ohms at 100 °C.

How do you calculate PT100 resistance?

R0 is the resistance of the RTD at 0°C. For a PT100 RTD, R0 is 100 Ω. For IEC 60751 standard PT100 RTDs, the coefficients are: A = 3.9083 • 10-3 • B = –5.775 • 10-7 • C = –4.183 • 10-12 The change in resistance of a PT100 RTD from –200°C to 850°C is displayed in Figure 1.

What is the output of PT100?

To do this we have used a simple potential divider, according to the voltage divider calculator when the value of Input voltage is 5V and R1 is 5.1K and the PT100 resistance is 1.8K (minimum) we will get an output voltage of 1.304V and when the value of PT100 is 39.02K (maximum) we will get an output voltage of 4.42.

### What does Pt and 100 indicates in a PT100 sensor?

Pt100 Working Principle The sensor type, Pt100, indicates two important pieces of information about the sensor. The first part, Pt, is the chemical symbol for Platinum and this shows that the sensor is Platinum-based. The second part, 100, relates to the resistance of the device at 0°C. In this case 100Ω.

How do you check PT100 with a multimeter?

Check Pt-100 sensor resistance: Connect the multimeter between two connection pins. Measure the resistance. Compare measured resistance to the values in engine manual, If the value is not zero or infinite,the sensor is working ok. Industrial grade pt100 temperature sensor.

How do you calculate temperature resistance?

The resistance R of an object also varies with temperature: R=R0(1+αΔT) R = R 0 ( 1 + α Δ T ) , where R0 is the original resistance, and R is the resistance after the temperature change.

## What is difference between RTD and Pt100?

There is no difference a PT100 is a version of a RTD (resistance temperature detector). What is an RTD? A resistance temperature detector, also known as an RTD or resistance thermometer, is a type of temperature sensor.

What is the temperature range of Pt100?

200°C to 650°C
A Pt100 features: A Platinum Resistant thermometer. -200°C to 650°C temperature range. ±0.1°C Accuracy.

What is the resistance value of PT100?

Its resistance value changes along with the change of temperature. Its name PT100 indicates that its resistance value is 100Ω at 0°C, and its resistance value is about 138.5Ω at 100°C.

### What is a PT100 signal conversion module?

Industrial applications, usually PT100 sensor signal is converted to dc current voltage signal for data acquisition and monitoring. The PT100 signal conversion module is a used to interface with PLC, DCS, temperature devices or instruments, etc.

How to test a PT100 sensor?

When user needs to check and test if a PT100 sensor works accurately or not, using a precision multimeter to measure its’ output resistance value is right or by referring the table above.

What is the PT100 simulator box?

Actually, the PT100 simulator box is a kind of precision resistance simulator box which is designed on the basis of PT100 Resistance Temperature Conversion Table below: And we have a precision 11 points PT100 simulator box designed based the PT100 resistance value, check details: RTD PT100 Sensor Signal Simulator Box
