Weighing plays a very important role in the production, circulation, sales, quality control, grading and other links of production in various industries. The usual practice is to directly connect the load cell to the weighing instrument or control system.

Since the sensor signal is relatively weak and the environmental conditions are usually harsh, the instrument must be installed nearby to avoid attenuation and interference caused by long-term transmission; and the range and characteristics of the sensors used under different weighing conditions are different, so most sensors and weighing instruments are used. Supporting use. The modular design in the weighing system digitizes the sensor signal, which can solve the above two problems to a certain extent. Aiming at the interference problem in the long-line transmission process of the weighing sensor signal and the generality of the weighing instrument, a A weighing transmitter digitizes sensor signals.

The weighing transmitter is an industrial-grade general-purpose multi-channel weight acquisition and transmission module, which can realize stable, reliable and high-precision industrial weighing, and output the weighing results through Ethernet, serial bus, Bluetooth, etc. Provide technical solutions for industrial control sites by weighing methods.

The weighing transmitter module can support up to 10 channels of independent work, each channel has an independent precision bridge source, with high accuracy and fast speed.

The weighing transmitter supports serial bus, supports 2 channels of RS-232 and 1 channel of RS-485 communication. All interfaces support standard Modbus RTU protocol, which can set interface parameters, sampling and filtering parameters, weighing platform setting parameters, measurement Value calibration parameters, tare and zero parameters, state detection parameters, etc.

weighing transmitterSupports all functions of WTM310-RS series modules, and also supports 2 Ethernet interfaces, which can cascade multiple modules through daisy chain. Ethernet supports standard MODBUS TCP\/IP protocol, standard MODBUS RTU Over TCP\/IP protocol , also supports HTTP protocol to read setting parameters.

The fast weighing transmitter module supports all the functions of the WTM310-RS series modules, and also supports the Bluetooth wireless communication interface, and the parameters of the module can be easily set through the mobile phone APP software.

WTM310 transmitter can be used for weight limit control and data acquisition, widely used in food, medicine, feed, metallurgy, chemical industry and other industries. The resistance strain sensor uses resistance strain gauge as the sensing element and Huygens bridge as the measurement circuit Its advantages are high measurement accuracy, wide measurement range, stable and reliable performance; simple structure, easy integration; good frequency response characteristics, strong adaptability to environmental factors, etc.
