What is the resistance of a PT1000?

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).

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 better than 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?


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.

Is Pt1000 linear?

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.

Where is Pt1000 used?

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 Pt1000 temperature sensor?

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.

Are all PT1000 sensors the same?

There are just a couple of differences between the two types of RTD sensors, the main one being the resistance value at 0°C; 100Ω for a Pt100 and 1000Ω for a Pt1000 but there are others. As well as the base resistance for a Pt1000 being ten times that of a Pt100, so is the fundamental interval.
