Low Speed Weighing Controller

The low speed weighing controller, a core component of low-speed dynamic truck scales, is independently developed, designed, and manufactured by Zhengzhou Hengliang Tech Co., Ltd. It features sensor status detection, zero-point tracking, scale setting, coefficient calibration, real-time vehicle passage data, weighing display, and real-time transmission. Its main function is to perform high-speed AD conversion on the input analog signals from the weighing sensors, process the data using algorithms, and integrate vehicle separation signals to calculate vehicle weight, number of axles, speed, and other information. The equipment has advantages such as fast speed, high precision, simple operation, high stability, and ease of maintenance.

The equipment provides two analog sensor input interfaces, one digital signal output, one discrete signal input, one axle signal input, one RS232 serial port output, and one RJ45 network interface supporting TCP/UDP communication. It includes a built-in 4G LTE wireless communication module, a 7-inch high-definition resistive touchscreen with a resolution of 1024*600, and a metrological verification seal interface.

Equipmeng Installation

As shown in the figure below, the weighing controller only has a touch panel on the front. The status indicators of the equipment are displayed in real time on the display screen, and the input and output interfaces are on the left and right sides of the equipment.

Zhengzhou Hengliang Tech Co., Ltd is a professional high and new tech enterprise, who specialized in developing, production and sales of quartz sensor (truck scales) , high speed WIM system, low speed WIM system, etc.

After 10 years intensive study of piezoelectric material, piezoelectric technology and algorithms, we developed quartz sensors, wheel Identifier sensor and other piezoelectric products based on piezoelectric technology, which were all highly accepted by the customer and market.

We have professional R&D team, well-equipped with complete process equipment, strict inspection system, and with strong quantity production capacity, at the same time, compared to similar products available in the market, our products owned the advantage such as high accuracy rate, long life span, no need maintenance, and easy construction etc, has been widely used and praised by the client.

We developed the quartz sensor, control system software by our own, have the intellectual property rights, and we own the invention patent of quartz crystal sensor and other patents and software copyrights.
