High Accuracy RTD Pt100 Temperature Sensor

Product Description

RTD temperature sensor is composed of platinum from IST, stainless steel probe, cable and connectors. The PT100 /PT1000 sensor is used for precise temperature monitoring applications, where errors in measurement have to be excluded. The linear relationship of the resistor to temperature, simplifies its use in many electronic applications.

The precision of the PT1000 allows its universal use for temperature monitoring, control and switching in windings, bearings, machines, motors, transformers and many other industrial applications.

Product FAQ

Q: What is the difference between PT100 and PT1000?

A: Pt100 sensors have a nominal resistance of 100Ω at ice point (0°C). Pt1000 sensors’ nominal resistance at 0°C is 1,000Ω. Linearity of the characteristic curve, operating temperature range, and response time are the same for both. The temperature coefficient of resistance is also the same. However, due to the different nominal resistance, readings for Pt1000 sensors are higher by a factor of 10 compared to Pt100 sensors. This difference becomes evident when comparing 2-wire configurations, where lead measurement error is applicable. For instance, the measurement error in a Pt100 could be +1.0°C, and in the same design a Pt1000 could be +0.1°C.

Q: What is the difference between 2, 3 and 4 wire RTDs?

A: 2 wire RTDs are the least accurate of the three types as there is no way of eliminating or calculating the lead wire resistance. This creates uncertainty in the reading therefore 2 wire RTDs are generally used with short lead wires where accuracy is not the main priority, they are mainly used in Pt1000 to reduce sensitivity and uncertainty (struggling to get a still reading as it is literally too accurate and the reading won’t stay still) but this means it will not be providing a very precise reading compared to 3 or 4 wire.

3 wire RTDs are the most commonly used RTD sensors, assuming all three lead wires are the same the third lead wire calculates the average lead wire resistance throughout the circuit and removes it from the sensor measurement. This makes 3-wire RTDs more accurate than the 2-wire alternative, but less accurate than 4-wire, however in circuits with long lead wires where there are long distances between the detector and the reading, significant savings can be made by using a 3-wire construction.

4 wire RTDs are used in applications where high accuracy is necessary. In a 4-wire RTD sensor the actual resistance in each of the lead wires can be measured and eliminated leaving the exact resistance of the detector. The 4-wire circuit works by using the first two lead wires to power the circuit whilst the 3rd and 4th wires read the resistance in each lead wire compensating for any differences in lead wire resistance.
