Product Details
High Precision Vehicle Overload Identification System & WIM
Scales
Product Function
The core component of the system is the quartz weighing sensor,
which is based on the piezoelectric principle. The measurement
process does not depend on deformation or elastomer. The whole
sensor is a completely rigid structure with a response time of μ
Class s (strain is MS), so there is no influence and error caused
by high and low speed in application, which can meet the needs of
high-speed weighing and measurement.

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.
