Quick Disconnect RTD Sensor Pt100 with 3 Pin Connector

A. Product Overview

Quick Disconnect RTD Sensor is an industrial temperature sensor used for accurate and reliable temperature measurement where easy removal and quick replacement are required.

Unlike a normal RTD sensor with fixed wiring, this sensor comes with a quick disconnect connector. This allows the user to plug and unplug the sensor easily without disturbing the complete wiring system. It is especially useful in applications where sensors need regular maintenance, calibration, cleaning or replacement.

This sensor generally uses a Pt100 simplex RTD element inside a stainless steel probe. The probe is inserted into the process or equipment, while the connector provides a secure and removable electrical connection.

Typical specifications include:

Element: Pt100 Simplex
Temperature Range: Minus 50°C to 500°C
Tip Diameter: 6 mm or 8 mm
Probe Length: 50 mm to 200 mm
Connection: 1/2 NPT optional
Wire Length: 0.5 meter to 10 meter
Termination: 3 pin flat connector

This RTD sensor is suitable for industrial machines, process equipment, HVAC systems, food processing equipment, pharmaceutical machinery and general temperature monitoring applications.

B. Working Principle

Quick Disconnect RTD Sensor works on the resistance temperature detection principle.

The sensing element inside the RTD sensor is usually made of platinum. In a Pt100 RTD sensor, the resistance value is 100 ohms at 0°C. When the temperature increases, the resistance of the platinum element also increases in a predictable way. This resistance change is measured by a temperature controller, indicator, transmitter, PLC or data logger and converted into a temperature reading.

The quick disconnect feature does not change the temperature measurement principle. It only makes the electrical connection easier and faster. The sensor probe measures the temperature, and the connector transfers the signal to the control system through the mating cable.

The main parts of a quick disconnect RTD sensor are:

Sensor probe with Pt100 element.

Protective stainless steel sheath.

Connector mounted on the sensor side.

Mating connector or cable assembly.

Temperature controller, transmitter, PLC or display unit.

Because the connector can be removed easily, the sensor can be replaced or calibrated without rewiring the complete system.

C. Why It Is Used

Quick Disconnect RTD Sensor is used where accurate temperature measurement is required along with easy maintenance and fast replacement.

In many industrial applications, sensor failure, calibration requirement or cleaning work can stop the machine or process. A quick disconnect RTD sensor reduces this downtime because the sensor can be removed and replaced quickly.

It is mainly used for:

• Fast sensor installation and removal.
• Easy calibration without major wiring changes.
• Quick replacement during maintenance.
• Accurate temperature measurement in industrial machines.
• Reducing downtime in process applications.
• Easy cleaning in food and pharmaceutical equipment.
• Temperature monitoring in HVAC and machinery systems.
• Reliable connection between sensor and control panel.

This sensor is useful when frequent maintenance is expected or when the sensor location needs to be accessed regularly.
