How to Protect Food Quality: Applications of Nexisense Compact Infrared Temperature Sensor

In today's fast-paced food processing industry, temperature control has become a key factor determining product quality, safety, and market competitiveness. From raw material handling to finished product dispatch, any temperature control mistake in every环节 may cause food safety hazards or economic losses. The Nexisense compact infrared temperature sensor, as an advanced technical solution, is quietly changing the industry's temperature management approach with its non-contact and real-time monitoring characteristics. This article will deeply explore the core advantages of this sensor, its practical applications in the food field, and how it helps enterprises achieve more efficient production processes.

Core Advantages of Non-Contact Measurement

Traditional temperature measurement methods, such as thermocouples or contact probes, often require direct contact with the food surface, which not only increases the risk of cross-contamination but may also affect measurement accuracy, especially in high-temperature or humid environments. In contrast, the Nexisense compact infrared temperature sensor adopts the infrared radiation principle, calculating temperature by capturing the infrared energy emitted by the object, achieving true non-contact measurement. This method avoids physical contact, ensures food hygiene and safety, and greatly reduces equipment maintenance requirements.

The response time of this sensor is only millisecond level, with accuracy up to ±1%, which is particularly valuable in dynamic production environments. For example, on high-speed production lines, it can instantly capture temperature fluctuations and avoid product defects caused by delay. More importantly, its anti-interference design enables stable operation in factory environments with strong electromagnetic noise. The housing is made of sandblasted aluminum alloy material, featuring excellent corrosion resistance and anti-fouling performance. Even in high-temperature steaming or frying workshops, it can work reliably for a long time, thereby extending equipment life and reducing downtime.

Key Applications in Food Processing

Food processing involves multiple complex stages, and temperature management at each stage directly affects the final product's taste, nutritional value, and shelf life. With its compact design and flexible installation method, the Nexisense compact infrared temperature sensor has been widely integrated into various equipment, helping enterprises optimize processes.

Precise Control in Baking and Frying Processes

In the baking process, the uniformity of oven temperature is crucial. Too high a temperature may cause bread to burn, while too low will affect fermentation. Using Nexisense sensors, enterprises can monitor the temperature distribution at multiple points inside the oven in real time to ensure even heat transfer. This not only improves product consistency but also reduces energy waste. According to industry data, precise temperature control can reduce the reject rate by more than 15%.

Similarly, in the production of fried foods such as potato chips or chicken nuggets, maintaining stable oil temperature is key to avoiding oil oxidation and the generation of harmful substances. The sensor can monitor the surface temperature of the frying pan in a non-contact manner and adjust the heating power in combination with an automated system to achieve closed-loop control. This helps maintain the oil temperature within the ideal range (such as 180-190°C), thereby extending oil service life and improving food safety standards.

Temperature Assurance in Steaming and Storage Stages

Steaming is a core step in many cooked food processes, such as canned food or quick-frozen vegetables. Nexisense sensors can be installed outside steaming equipment to monitor steam temperature and food surface heat, ensuring the sterilization process is thorough without destroying nutritional components. In the storage stage, especially for perishable dairy products or meat, it can detect warehouse ambient temperature and promptly alert abnormal fluctuations to prevent bacterial growth.

In addition, this sensor performs excellently in temperature detection before packaging. It can quickly scan the food surface to ensure that the product is cooled to a safe temperature (such as below 4°C) before entering the packaging line, avoiding condensation or microbial contamination. This efficient monitoring method allows enterprises to shift from passive response to active prevention.

Cold Chain Transportation and Logistics Monitoring

The cold chain is the most vulnerable link in the food supply chain, and temperature fluctuations may lead to the scrapping of entire batches of products. The Nexisense compact infrared temperature sensor is suitable for cold storage, transport vehicles, and containers. Through wireless communication protocols (such as Modbus or RS-485), it connects with the central system to achieve remote real-time monitoring. For example, during long-distance transportation, the sensor can monitor the cargo hold temperature and send alerts when the threshold is exceeded, helping logistics teams intervene quickly.

Actual cases show that after introducing such sensors, the cold chain interruption rate can be reduced by 20%, significantly lowering economic losses. At the same time, its low-power design ensures long-term operation in battery-powered environments, suitable for food distribution in remote areas. This not only protects food quality but also complies with international food safety standards such as HACCP requirements.

Technical Specifications and Integration Convenience

The core of the Nexisense compact infrared temperature sensor lies in its high-performance module: the measurement range covers -20°C to 1000°C, suitable for various scenarios from freezing to high-temperature processing. The resolution is up to 0.1°C, ensuring that even small changes can be captured. The device supports multiple output interfaces, including analog 4-20mA signals and digital I2C protocol, facilitating seamless integration with PLC systems or IoT platforms.

In terms of design, its compact size (usually less than 50mm×50mm) allows installation in tight spaces, such as beside conveyor belts or inside equipment. The protection rating reaches IP65, which can resist water vapor and dust erosion, meeting the cleaning requirements of food factories. Compared with traditional sensors, it requires no frequent calibration, resulting in lower maintenance costs and helping enterprises achieve digital transformation.

To further enhance practicality, Nexisense provides customization services, such as adjusting the field of view (FOV) to match specific application scenarios. This makes the sensor not just a measurement tool, but part of an intelligent production system.

Industry Cases and Actual Benefits

Many food companies have successfully applied Nexisense sensors. For example, a large bakery optimized oven temperature control by deploying these sensors, reducing energy consumption by 10% while increasing product qualification rate to 98%. Another dairy company used it in the cold chain link, reducing temperature anomaly events during transportation and extending product shelf life.

These cases prove that precise temperature management can not only improve efficiency but also enhance brand reputation. In a highly competitive market, enterprises that adopt advanced technologies such as Nexisense sensors can better meet consumers' demand for high-quality food and comply with strict regulatory requirements.
