Development History
2005
Zhuzhou Zhonghang Technology Development Co., Ltd. was established in February, 2005.
2006
Our engineers were the first ones in our industry to developed ZA21 two-wire eddy current displacement sensor/transducer and ZA series super-high-temp. eddy current sensor and ZA-H2 series two-wire integrated vibration velocity sensor in March,2006.
2006
Our engineers were the first ones in our industry to solve the interchangeability of probes and proximitors in July, 2006.
2006
Our engineers successfully developed ZA-TJ series eddy current pipe diameter measuring sensor in September, 2006.
2006
In July, 2006, our engineers were the first ones in our industry to make a breakthrough in the philosophy of eddy current and raise the measuring range of sensor to almost the diameter of probe head.
2007
The ISO9001 international quality system certificate was awarded in Dec. ,2007.
2007
our engineers were the first in our industry to overcome the difficulties in eddy current technology to raise nonlinearity of common displacement sensor to less than 0.2%（Chinese national standard is 1%）
2007
Our engineers were the first ones in our industry to successfully developed ZA-YD series piezoelectric vibration velocity / displacement sensor in April, 2007.
2008
The company's product ZA21 series two-wire eddy current sensor has passed the certification of high-tech products in Hunan Province. At the same time, Zhuzhou Zhonghang Technology Development Co., Ltd. was recognized as a high-tech enterprise.
