Digital vibrating wire sensor---DSensor

 

Thanks to the remote powerless electronic tag technology, the electronic tag with only 3mm*10mm is embedded into the vibrating wire sensor, which enables the four-wire vibrating wire sensor to have intelligent functions such as ID identification, temperature reading and automatic physical quantity acquisition.

FUNDAMENTALS

First, an electronic tag installed inside the sensor can measure real-time temperature. Second, the tag stores the ID and calculation parameters of the sensor. Finally, a special readout is used to connect the sensor, and the screen automatically displays real-time frequency, temperature, sensor type, physical Value, manufacturer and other information.

Embeddable Micro Tag MT01

MT01 is a two-wire electronic temperature sensor with storage function, which can be provided to vibration sensor manufacturers embedded into the sensor interior, to achieve information pre-storage, ID identification, temperature acquisition. Through a series of energy saving and communication technologies, it can realize communication function up to 800 meters without power supply.

Miniature size that can be embedded into any vibrating wire sensor.

Provides programmable tools

DSensorTool is a computer software tool that can read the internal information of MT01 and write new information and parameters into the MT01.

This tool is freely available to sensor manufacturers to make their own smart sensors.

Intelligent detection

VH03, a special readout meter, can be used to check whether the electronic tag has been connected. If it is not detected, the screen will display normal frequency and temperature; otherwise, the screen will automatically switch to the DSensor interface. The dynamic detection of the readout and the unique algorithm of the cable resistance and parasitic capacitance have solved the long-distance communication problem of electronic tags and made the communication distance reach an astonishing 800 meters, which can meet the needs of most engineering applications.

DSensor mode saves a lot of time for data acquisition and data calculation by measurement engineers, and also avoids the occurrence of calculation errors.

Multitype signal

VH03 also adds the function of current and voltage signal acquisition and RS485 interface, which can connect and read these sensors. These types of signals represent more than 90% of current sensor types, making the VH03 a versatile and highly adaptable readout.

Storage Function

The internal storage size of VH03 can store not less than 250,000 data records. You can view all historical data on a spreadsheet page.

Data synchronization

VH03 can be connected to the external USB disk to export the internal storage data with a single key. In addition, VH03 has a standard MicroUSB interface for exporting data to Excel files when connected to a computer.

The data can also be synchronized using VH03's Bluetooth and Lora wireless network.

Wireless communication

Bluetooth 4.2 BR EDR+BLE+ 2.4Ghz) and Lora (420~450MHz) are built into VH03. Through the wireless interface, VH03 can complete data interaction with the wireless host (such as real-time data reading, historical data download, etc.).
