What type of temperature sensor is the WZPT-03?

The WZPT-03 is a PT100 RTD (Resistance Temperature Detector) temperature sensor that uses a platinum resistance element for accurate and stable temperature measurement.

What is the temperature measurement range?

The sensor can measure temperatures from -100°C to 300°C, making it suitable for both low-temperature and high-temperature industrial applications.

Is the probe waterproof?

Yes. The WZPT-03 features a stainless steel probe structure designed for temperature measurement in water, oil, and other non-corrosive liquid environments.

What material is used for the probe?

The probe is made of stainless steel, providing excellent corrosion resistance, durability, and long service life in industrial environments.

What is the installation method?

The sensor is equipped with an M12×1 fixed threaded connection, allowing secure and reliable installation in tanks, pipelines, and process equipment.

What is the response time of the sensor?

The thermal response time is ≤20 seconds, enabling the sensor to quickly detect temperature changes and provide stable measurement results.

What media can this sensor measure?

The WZPT-03 is suitable for measuring the temperature of: Water Oil Air Steam Other non-corrosive liquids and gases

What industries commonly use this sensor?

Typical applications include: Industrial automation systems Water treatment equipment HVAC systems Boilers and heating equipment Food processing machinery Chemical process control Laboratory and testing equipment

What are the dimensions of the probe?

The standard probe size is: Length: 251 mm Diameter: 7 mm Custom specifications may be available upon request.

What is the difference between a PT100 sensor and a thermocouple?

A PT100 sensor measures temperature based on the resistance change of platinum and generally provides higher accuracy and better stability than thermocouples, especially for industrial process monitoring applications.

Does the sensor require a temperature transmitter?

The WZPT-03 outputs a PT100 resistance signal. If your control system requires a standard output such as 4–20mA, 0–10V, or RS485, an external temperature transmitter is required.

Can the cable length and probe size be customized?

Yes. Customized probe lengths, cable lengths, connection types, and installation threads can be provided according to specific application requirements.

How should the sensor be maintained?

Regularly inspect the probe for contamination, scale buildup, or mechanical damage. Keeping the sensing area clean helps maintain measurement accuracy and prolong service life.

Is the sensor suitable for continuous industrial operation?

Yes. The stainless steel construction and PT100 sensing element are designed for long-term, continuous operation in industrial temperature monitoring and control systems.
