RTD PT100 Industrial Temperature Sensor Probe, KNE Head, 3 Wire, +250°C Max, 4-20mA Transmitter

The PPL3-P RTD temperature sensor with KNE terminal head is a robust industrial probe and has a wide RTD temperature range of -75 to +250°C.

The TIG welded plain 6mm diameter stem of the probe is fabricated from 316 stainless steel and is pressure tight. The fitting into the terminal housing is also welded rather than a compression fitting.

This design is far more suitable for applications in the food industry where cleanliness is necessary or where vibration is present as it is a far more robust method of mounting the head.

The RTD for temperature measurement KNE terminal head is made from aluminium alloy and has a silver painted finish. It has an ingress protection rating of IP68. The lid of the terminal head screws on and is retained by a stainless steel chain.

Inside the RTD Pt100 terminal head is a 4-20mA output temperature transmitter which allows transmission of the RTD sensor signal over much greater distances without loss of accuracy. A simple 2-core cable is all that is required to connect the sensor and your instrumentation.

The RTD transmitter is loop powered and accepts a power supply of between 10 and 30 Volts d.c. The standard range is 0 to 100°C but we can configure the transmitter to any range between -75 and 250°C (the range of the sensor). Let us know if you need a wider range and we’re happy to assist.

Easily mount this resistance temperature detector sensor in ducting, pipework or tanks and vessels using a suitable mounting such as a compression fitting or thermopocket. Supplied as standard as a Class B 3 wire measurement system, the accuracy at 0°C the accuracy is +/-0.3°C.

RTD Temperature Sensor Additional Information

The PPL3-P RTD pt100 temperature sensor with KNE head is ideal for use with compression fittings or our PPL50-TW pocket making them easy to install in your process. The RTD industrial sensors are also available as a PPL3 thermocouple.

What is an RTD Sensor? Resistance Temperature Detector

RTD stands for "Resistance Temperature Detector" and is a type of temperature sensor device that uses the principle of electrical resistance to measure temperature. The resistance can be measured and converted to a temperature reading. RTD temperature sensors are known for their high accuracy and stability over a wide range of temperatures. They are often used in temperature control systems, process control, and laboratory equipment.

What is a Pt100 Probe?

A Pt100 probe is a type of RTD (Resistance Temperature Detector) that uses platinum as the sensing element. Specifically, the "Pt" in Pt100 stands for platinum (platinum wire or film), and the "100" refers to the resistance value at 0°C - 100 ohms. Platinum is the most reliable metal due to its linear resistance to temperature relationship over a large temperature range.

The Pt100 probe the most rugged form of RTD is designed to measure temperature with high accuracy and stability. The Pt100 sensor is mounted inside a metal sheath or probe, which protects it from being damaged by the surrounding environment. The resistance of the platinum wire changes in response to temperature, allowing the temperature to be measured. Pt100 probes are often used in applications that require precise temperature measurement.

How Does an RTD Sensor Work?

An RTD sensor works by measuring the change in electrical resistance of a wire, typically platinum, with temperature. Platinum is preferred due to its stability and linear resistance-temperature relationship. As the temperature increases, the resistance of the wire also increases. This change in resistance is used to calculate the temperature.

What is a 4-20ma Temperature Sensor?

A 4-20mA temperature sensor is a type of temperature sensor that provides output in the form of a current signal ranging from 4 mA to 20 mA. The current value corresponds to the temperature being measured, with 4 mA representing the lowest temperature and 20 mA representing the highest.

What is the RTD Temperature Range?

The RTD temperature range is typically in the range of -200°C to 850°C (-328°F to 1562°F). This range may vary based on the type of RTD and the specific materials used in its construction.

What is a PT100 Temperature Sensor?

A PT100 temperature sensor is a Resistance Temperature Detector (RTD) with a nominal resistance of 100 ohms at 0°C, following IEC 60751. It features a platinum resistor, offering stability and corrosion resistance. Suitable for industrial processes and gas temperature measurement, PT100 sensors provide a fast response time and withstand temperatures up to 600°C. They come with various lead wire options like copper and nickel, and standard IEC connectors for easy integration.
