What is a Pt1000?
Pt1000 sensors are part of the group of temperature sensors called Resistance Temperature Detectors or RTDs for short. They use the principle of changing electrical resistance with changing temperature for the measurement of temperature.
What is Pt1000 and Pt100?
The main difference between Pt100s and Pt1000s in general is the electrical resistance at 0⁰C, which is the number in the name: a Pt100 is 100Ω at 0⁰C and a Pt1000 is 1000Ω at ⁰C. This makes Pt1000s more accurate for small temperature changes as they would result in larger changes in resistance when compared to Pt100s.
Is Pt1000 a thermistor?
The Y parameter defines the sensor type, “thermistor” or “pt1000”. The T parameter (T100000) means that the resistance at 25C is 100Kohms. The B parameter (B4725) means that the thermistor B value over the temperature range of interest is 4725.
Where can I use Pt1000?
In general, Pt100 temperature sensors are more commonly found in process applications, while Pt1000 sensors are used in refrigeration, heating, ventilation, automotive, and machine building applications.
What is the output of Pt1000?
The output signal generated by a Pt1000 thermometer can, among other things, be connected to a PLC. A Pt1000 transmitter is required for this, which then outputs a signal of 4–20 mA or, in the case of a Pt1000 transmitter, 0-10V.
What is an NTC what is it used for?
NTC stands for “Negative Temperature Coefficient”. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices.
What is the temperature range of Pt1000?
-50 to +500 °C.
Characteristics of Pt1000 Sensors The temperature range of Pt1000 temperature sensors extends from -50 to +500 °C. Outside of this range, we recommend the use of a thermocouple. The minimum diameter of Pt1000 probes is typically 3 mm. If you require a smaller diameter, we recommend to use a Pt100 or a thermocouple.
What is the difference between PTC and Pt1000?
– PT100 is an RTD (Resistance Temperature Probe) made of Platinum metal which has a resistance value of 100 ohms at zero degrees celsius. – PTC (Positive Temperature Coefficient) and NTC (Negative Temperature Coefficient) are both types of Thermistor. NTC have resistance that decreases with increasing temperature.
How accurate are Pt1000?
Sensor manufacturers offer a wide range of sensors that comply with BS1904 class B (DIN 43760): these sensors offer an accuracy of ±0.3 °C at 0 °C. For increased accuracy, BS1904 class A (±0.15 °C) or tenth-DIN sensors (±0.03 °C). Companies like Isotech can provide standards with 0.001 °C accuracy.
Is Pt1000 linear?
This relationship is linear and in general very accurate. In industry, Pt100 or Pt1000 resistance thermometers are the most popular ones. The resistance on a Pt100 thermometer is 100 ohm for 0°C, for a Pt1000 this resistance is 1000 ohm for 0°C.
How do you test a Pt1000 sensor?
A – The first step of identifying an RTD is finding out how many wires it has (2, 3 or 4), you can then connect the RTD to a multimeter, it should read between 107 – 110Ω at room temperature if it is a pt100. However, if it is a pt1000 you should get a reading of 1007 – 1100 Ω which confirms that it is a Pt1000.
What is the accuracy of PT1000?

---|---|---|
Temperature | -50–200 °C | ± (0,25 + 0,002|t|) |
What is the resistance of a PT1000?
Pt refers to that the sensor is made from Platinum (Pt). 1000 refers to that at 0°C sensor has a resistance of 1000 ohms (Ω).
Is NTC same as RTD?
RTDs are thermally sensitive resistors similar to NTC thermistors. However, unlike NTCs thermistors, RTDs exhibit a positive temperature coefficient of resistance—that is, they increase in resistance as temperature increases (Figure 2).
How is Pt1000 measured?
For a Pt100, this coefficient is about +0.4 ohm/°C at 0°C and +0.35 ohm/°C at 300°C. For a Pt1000, the behavior is exactly the same, but the coefficient has to be multiplied by 10….Temperature measurement. with a Pt100 (or Pt1000) sensor.

Why platinum is used in RTD?
Platinum film is used in the construction of RTDs because it is stable, provides repeatable and measurable results and has a broad temperature range. The way RTDs are constructed makes them more rugged and reliable in harsh conditions which is why it can be used in industrial and critical applications.
