Differences Between Temperature and Humidity Sensors with Built-In and External Probes
With the fast-paced progress of modern society, temperature and humidity sensors have become widely used across various fields. Temperature and humidity play an essential role in everyday life, influencing comfort, safety, and efficiency in multiple industries. Manufacturers typically equip these sensors with built – in or external probes to meet different application needs. But what distinguishes these two types in terms of function and usage?
Built-In Probe
Temperature and humidity sensors with built – in probes have internal sensing elements, hiding the sensor from view. This design results in a sleek, aesthetically pleasing appearance.
Built – in probes use little power and are less impacted by external factors like aging, vibration or volatile chemicals. This ensures greater long – term stability. Installed as a single unit, they are ideal for monitoring overall environmental conditions in open spaces. Common use cases include:
– Data centers
– Smart buildings
– Warehouses
– Laboratories
– Clean rooms
External Probe
Sensors with external probes feature a sensing unit that is separate from the main device. This separation enables the user to achieve a broader measurement range since it doesn’t confine the sensor within the same housing as its display and electronic circuitry. External probes are particularly well-suited for measuring small or confined spaces like:
– Drying ovens
– Constant temperature chambers
– Refrigerators
Specialized external probes can measure in unique environments like sealed spaces, pipelines, control boxes, or grain storage piles. You can insert them directly into the monitored medium. We construct many external probes from materials like metal to enhance their durability, waterproofing, and resistance to condensation.
There are also multiple types of external probes tailored to specific needs:
– **Hardcover Probes**: Versatile and suitable for most uses; sensitive, waterproof, and dustproof.
– **Waterproof Probes**: Ideal for high-dust environments; less sensitive than hardcover probes in detecting minute changes.
– **Metal Waterproof Probes**: Designed for high-dust conditions with higher sensitivity than regular waterproof probes.
– **Quarter-Pipe Threaded Probes**: Useful for containers with threaded installations, enabling accurate temperature and humidity readings inside enclosed devices.
– **High-Temperature Probes**: Specifically engineered to operate at temperatures above 80°C.
Calibration: A Crucial Component
Temperature and humidity sensors rely on a combination of advanced electronic technology and physical/chemical principles to provide accurate readings. However, hardware itself contributes only about 50% to the sensor’s performance; calibration is equally critical. To keep measured values accurate over time, sensors need frequent calibration to maintain consistency within set ranges. This is a difficult task in many applications.Precision and stability remain paramount benchmarks for temperature and humidity sensors.
Understanding Their Core Functions
Beyond using integrated or external probes, temperature and humidity sensors can be distinguished by their specific focus:
1. **Temperature Sensors**: These devices detect the temperature of an object or the environment and then convert it into a measurable signal through a transmitter.
2. **Humidity Sensors**: This device is primarily used to measure the moisture levels in the air or objects. It sends the data to a connected system for further processing.
Key Advantages of Temperature and Humidity Sensors
The temperature and humidity sensor initially developed features a compact design with an elegant and aesthetically pleasing appearance. Besides its main function, it doesn’t just measure and record temperature and humidity. It also acts as a decorative item for indoor areas.
When it comes to performance, the sensor is highly reliable, providing accurate and consistent measurements. It can detect temperatures ranging from -40℃ to 60℃, with an accuracy of ±0.5℃. Humidity measurements range from 0 – 100% RH with a precision of ±3% RH, ensuring reliable readings in different conditions.
Developers have also equipped this sensor with advanced software capabilities, enabling seamless data uploads to a cloud platform. The software offers a comprehensive set of features, making it highly convenient for users to view and manage data. Users can access real-time readings from the sensor anytime and from anywhere. For further processing, you have the option to save data in formats like EXCEL or TXT, facilitating seamless integration into different workflows.
A standout feature of the sensor is its high-definition LCD screen, which makes real-time data easy to read. It also includes an automatic alarm system that activates when temperature or humidity readings exceed pre-set thresholds.
In such cases, the device sounds a buzzer alarm and sends notifications via SMS, phone call, and email. Customers can adjust key settings via intuitive button controls. These tasks consist of setting the upper and lower limits of temperature and humidity alarms, changing the baud rate, and setting the address.
In terms of usability, the sensor incorporates a user-friendly design concept. Its versatile back panel includes options for mounting on a wall or placing on a countertop with the included bracket. Moreover, a quick – action key switch simplifies operations and boosts convenience during installation or normal use.
In today’s evolving market, environmental monitoring systems have reached new heights in functionality and efficiency. These systems are becoming popular because they’re adaptable and have various designs for different needs.
