Profile: Shanghai HaoYing Measurement & Control Technology Co., Ltd specializes in sensors and controlling systems. We are an ISO 9001:2000 and CE certified company. Our products include melt pressure transducers, pressure gauges, load cells, melt pressure transmitters, digital pressure indicator, level transducers, temperature transmitter, wheel & axle dynamic weighing system, PID intelligent pressure controller and intelligent melt pressure transmitter. The melt pressure transducers are constructed with steel stem, flex tube and diaphragm. These are suitable for pressure measuring & controlling in high temperature liquid medium of chemical filature, polyester, and equipment rubber plastic machine. The pressure transducers are made up of stainless steel with corrosion resistance & in various configurations. These are suitable for measuring and controlling in hydraulic pressure, die-casting, center air-condition system, constant pressure water supply & air compressor. Our HY series of portable wheel & axle dynamic weighing system is suitable for different types of vehicle weighing both dynamically and statically. It has the advantages of high precision, small size, light weight and ease of operation comparing to fixed vehicle weighing systems. The HY series of weighing system consists of two main parts such as weigh-pad and weighing instruments. The weigh-pad is made of aluminum alloy or mixed aluminum alloy and stainless steel, which can load from 1 ton up to 40 tons. Our products are used in various applications including plastic-rubber machine, fiber machine, petrochemical industry, sewage disposal, power plant, aerospace equipment, compressor, air-conditioner, automobile, packing machine, medical apparatus and food processor. We also export our products to various countries worldwide.
