Overview

The Pt100 3-wire RTD sensor is a high-performance temperature sensor designed for precise and reliable temperature measurement across a wide range of industrial applications. With a measuring range of -200°C to 420°C, it offers exceptional accuracy and fast thermal response, making it ideal for environments that demand high precision. Available in various lengths, this SUCH sensor also features a smaller diameter than traditional assembly-type thermocouples. The sensor utilizes imported thermoresistance elements and stainless steel protective sheath, ensuring high sensitivity, accuracy and resistance to contamination.

Feature

3 wire RTD sensor detail

The RTD sensor has a smaller diameter compared to assembly-type thermocouples, is more flexible, and has better vibration resistance. It can be installed in places where assembly-type thermocouples cannot be used.
It uses imported thermoresistance temperature sensing elements, which are more precise, sensitive, and have a fast thermal response time.
This SUCH sensor offers greater stability and a longer service life.
The protective sheath of the thermistor is made of stainless steel, filled with a high-density oxide insulating material, which gives the thermistor excellent resistance to contamination.
The temperature measurement range is wide, from -200°C to 420°C, with good electrical output characteristics.

Accuracy

Division No.	Allowable Deviation
Pt100	Class B (-200℃-800℃) Tolerance ±(0.30+0.005\|t\|)
	Class B (-200℃-650℃) Tolerance ±(0.15+0.002\|t\|)
Note: "t" in the formula represents the absolute measured temperature of the temperature sensing element.
Thermoresistance temperature sensor element (RTD) resistance ratio at 100°C (R100) to resistance at 0°C (R0): For Pt100: Class A: R0=100 ± 0.06Ω Class B: R0=100 ± 0.12Ω R100/R0 ratio=1.3850
Thermal response time: The time required for the resistance temperature detector (RTD) to reach 50% of the output change corresponding to a step change in temperature is called the thermal response time, denoted as T0.5.
Nominal pressure of the resistance temperature detector (RTD): Generally refers to the static external pressure that the protective tube can withstand without rupture at room temperature. In reality, the allowable operating pressure is not only related to the material, diameter, and wall thickness of the protective tube but also to its structural form, installation method, insertion depth, and factors such as the flow velocity and type of the measured medium.
Insulation resistance: The test voltage for insulation resistance at room temperature can range from DC 10V to 100V at any value. The ambient temperature should be within the range of 15-35°C, and the relative humidity should be greater than 80%. The insulation resistance value at room temperature should not be less than 100MΩ.
Allowable current through the resistance temperature detector (RTD): The maximum measuring current through the RTD should not exceed 5mA.

FAQ

Q1: What is a Pt100 3 wire RTD sensor? ❯

A Pt100 3 wire RTD sensor is a temperature sensor that uses a platinum resistance element (Pt) to measure temperature. The "100" refers to the resistance value of the platinum element at 0°C, which is 100 ohms. The "3 Wire" design helps reduce the impact of wire resistance on the measurement, making it more accurate, especially for long cable runs.

Q2: What is the working principle of a Pt100 3 wire RTD sensor? ❯

The Pt100 3 wire RTD sensor operates by measuring the change in resistance of the platinum element as temperature changes. Platinum's resistance increases with temperature in a well-known linear relationship. The 3-wire configuration helps eliminate errors caused by the resistance of the wires by compensating for the resistance of the lead wires, ensuring accurate measurements even over longer distances.

Q3: Why choose a Pt100 3 wire RTD sensor? ❯

A Pt100 3 wire RTD sensor offers high accuracy and reliability, making it ideal for precise temperature measurements in industrial and laboratory applications. The 3-wire configuration improves measurement precision by compensating for lead wire resistance. It is widely used in industries like chemical processing, food production, and environmental monitoring due to its stability, long service life, and high resistance to contaminants.
