Temperature sensor refers to a device that can sense the temperature of the surrounding environment or a specific object and convert it into a standardized output signal (such as voltage, current, resistance or digital signal) that can be used for measurement, recording, display, control and other purposes. This kind of sensor is the key component in the temperature measurement system, its function is to accurately and reliably capture temperature information, in order to monitor, analyze or control the thermal state of the measured object in real time. As an important component in modern industrial automation, environmental monitoring, medical equipment, smart home and other fields, temperature sensor's accuracy, stability and intelligence directly affect the operation efficiency and data accuracy of related systems.

Introduction to the SVT100

The SVT100 is an ultra-low power wireless vibration and temperature sensor designed for machine condition monitoring. It has the advantages of easy installation, easy use, high battery power efficiency. The SVT100-A consists of a low-power wireless IC, a high-performance 3-axis accelerometer, and a high-precision temperature sensor. It can monitor machine status in real time or on schedule. Multiple SVT100-As can be grouped together and divided into different groups of wireless switches. They provide advanced monitoring and analysis capabilities simultaneously.

Material and structural design

The SVT100 sensor is made of high-quality metal or ceramic materials with high temperature resistance, oxidation resistance and corrosion resistance to ensure long-term stable operation in harsh environments. The probe is compact in design and small in size, making it easy to install in a small space. Protection grades up to IP67 or IP68, with excellent water and dust resistance, suitable for outdoor, wet or dusty environments. Some models are also equipped with seismic structures and compensation wires to effectively reduce the impact of mechanical vibration and temperature changes at the cold end of the thermocouple on the measurement results.

Intelligent function

The SVT100 temperature sensor integrates advanced digital signal processing technology and wireless communication modules (such as Bluetooth, Wi-Fi, LoRa, etc.) to support real-time data transmission, remote monitoring, alarm setting, data recording and analysis. Some models are equipped with a self-calibration algorithm, which can automatically adjust the measurement parameters according to environmental conditions, further improving the measurement accuracy. In addition, some products are also compatible with various industrial bus protocols (such as Modbus, Profibus, CAN, etc.), easy access to existing automation control systems.

• Advantages of SVT100-A
  Thanks to its unique low-power design, the SVT100-A can operate for up to five years (depending on the frequency of use and the environment) before the battery is replaced. The SVT100-A is easy to install and configure, solving the complex problem of wireless sensor setup. The SVT100-A is designed to operate in harsh environments. It has a secure boot loader for increased security. Support OTA (Over the Air) firmware upgrade. The SVT100-A has six operating modes: real-time mode, synchronous real-time mode, batch mode, synchronous batch mode, single data acquisition and synchronous single data acquisition.
  . Real-time mode: When the sensor wakes up, data acquisition and transmission begin immediately.
  . Batch mode: When the sensor wakes up, it takes a fixed amount of data at a given sampling rate and transmits the data together to the gateway, then repeats the process.
  . Single data acquisition: When the sensor wakes up, it acquires a fixed amount of data at a given sampling rate and transmits the data to the gateway once. The sample rate is guaranteed and is very suitable for frequency domain analysis.
  . Synchronous mode: Synchronous mode can be combined with real-time mode, batch mode, or a single DAQ. After awakening, the same group of sensors begin data collection and transmission at the same time. This feature is useful for advanced analysis.
