JENNIE | 2025-10-22
In the fields of industrial automation, petrochemicals, energy and power, temperature measurement is a critical link in ensuring safe equipment operation and process stability. However, when facing complex working conditions such as high temperature, high pressure, strong corrosion, humidity, and intense vibration, traditional temperature sensors often suffer from slow response, accuracy drift, sealing failure, and short service life, causing numerous problems for on-site engineers.
So, is there a sensor that can handle multiple complex working conditions simultaneously? The answer is yes. This article will systematically explain a multifunctional temperature sensor that integrates Waterproof RTD Temperature Sensor for Industrial Automation, High-Accuracy Thermocouple Probe for Petrochemical Plants, and Industrial flange temperature – helping you solve temperature measurement problems in complex working conditions with one solution.

Applicable Scenarios
-
Food and beverage production lines (requiring frequent washing)
-
Pharmaceutical workshop clean areas and fermentation tanks
-
Outdoor control cabinets and pipeline monitoring
-
Cold storage and high-humidity environments
II. High-Accuracy Thermocouple Probe for Petrochemical Plants: How to Handle High-Temperature Corrosive Environments?

VI.Frequently Asked Questions
Q1: Does this sensor use RTD or thermocouple?
Both. This sensor can be configured as either a platinum RTD or a thermocouple based on your specific working conditions. RTD is suitable for medium-to-low temperature high-accuracy measurement (-200°C to 500°C), while thermocouples are suitable for high-temperature environments (0°C to 1200°C). The same sensor structure supports flexible selection of both sensing elements.
Q2: What does IP68 waterproof rating mean? Can it be submerged in water?
Yes. IP68 means the sensor can be immersed in water for long periods without damage. Our Waterproof RTD Temperature Sensor for Industrial Automation technology uses a fully sealed laser welding process, ensuring stable signals even when working continuously underwater.
Q3: Does flange installation require on-site welding?
No. This Industrial flange temperature uses standard flange connections. The sensor's own flange is bolted to the matching flange on the pipe or container – no hot work or welding required. Installation is convenient, fast, and safe.
Q4: What is the accuracy of the thermocouple in high-temperature environments?
High accuracy. Our High-Accuracy Thermocouple Probe for Petrochemical Plants uses precision-grade thermocouple wire with measurement error ≤ ±0.4%t (e.g., ≤ ±4°C at 1000°C). It offers excellent long-term stability and is suitable for harsh scenarios such as petrochemical plants.
Q5: Can the probe length and flange specifications be customized?
Yes. Probe insertion depth, flange standards (DN25/DN40/ANSI 1"/custom), and protection tube materials (304/316L/Inconel 600) all support on-demand customization to ensure perfect matching with your on-site equipment.
Q6: What signals does this sensor output?
It supports multiple output methods: 4-20mA analog, RS485 (Modbus RTU), PT100 direct resistance output, and more. You can choose flexibly based on your control system.
Q7: How do I determine which configuration is suitable for my working conditions?
It is recommended that you provide the following parameters: measurement temperature range, medium type (corrosive or not), installation interface type (flange/thread), and environmental conditions (humid/vibrating or not). Our technical team will recommend the optimal configuration based on your specific working conditions.
