What is the difference between WRNT-01 and WZPT-01?

The WRNT-01 is a spring-loaded thermocouple available in K, E, and J calibration types, while the WZPT-01 is a spring-loaded RTD temperature sensor that uses a PT100 platinum resistance element. Thermocouples are generally suitable for wider temperature ranges, while PT100 sensors provide higher accuracy and stability.

What sensor types are available in this series?

This series supports multiple sensing elements, including: K Thermocouple (WRNT-01) E Thermocouple (WRET-01) J Thermocouple (WRJT-01) PT100 RTD (WZPT-01) Cu50 RTD (WZCT-01) Users can select the appropriate model according to their application requirements.

Why does the sensor use a spring-loaded design?

The spring-loaded structure maintains continuous contact between the probe tip and the measured surface, improving heat transfer efficiency, measurement accuracy, and response speed.

What is the temperature measurement range of the WZPT-01?

The WZPT-01 PT100 model has a measurement range of -50°C to 200°C, making it suitable for most industrial temperature monitoring applications.

What is the response time of the sensor?

The thermal response time is ≤20 seconds, allowing the sensor to quickly detect temperature changes and provide reliable readings.

What material is used for the probe?

The probe is made of stainless steel, offering excellent corrosion resistance, mechanical strength, and long service life in industrial environments.

What are the dimensions of the WZPT-01?

The standard dimensions are: Probe Length: 64 mm Probe Diameter: 5 mm The compact design allows installation in limited spaces.

What is the thread specification?

The sensor adopts a fixed threaded connection of M12 × 1.5, ensuring secure and stable installation on equipment and machinery.

What applications are suitable for this sensor?

Typical applications include: Injection molding machines Heating equipment Mold temperature control Industrial automation systems Packaging machinery HVAC systems Process temperature monitoring Laboratory equipment

Can the sensor be used in vibrating environments?

Yes. The spring-loaded structure helps maintain stable contact under vibration conditions, making it suitable for industrial machinery and equipment with mechanical movement.

What is the difference between PT100 and Cu50 sensors?

PT100 sensors provide higher accuracy, better stability, and wider industrial acceptance. Cu50 sensors are more economical and are commonly used in basic temperature measurement applications.

Can the sensor be connected directly to a PLC?

The WZPT-01 outputs a resistance signal (PT100 or Cu50), while the WRNT-01 outputs a thermocouple signal. If the PLC does not support these inputs directly, a temperature transmitter may be required to convert the signal to 4–20mA, 0–10V, or RS485.

Is customization available?

Yes. Customized probe lengths, cable lengths, thread types, sensing elements, and connection methods can be provided according to specific application requirements.

How should the sensor be maintained?

Regularly inspect the probe and connection threads for contamination, looseness, or mechanical damage. Keeping the sensing surface clean helps maintain measurement accuracy and prolong service life.

Is this sensor suitable for long-term industrial operation?

Yes. The stainless steel construction, spring-loaded design, and industrial-grade sensing elements are designed for reliable long-term operation in industrial temperature measurement and control systems.
