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.
