China's explosion-proof shearer coming soon

Recently, the reporter learned from Taiyuan Mining Machinery Group Corporation, a new type of coal shearer that can effectively prevent underground gas explosion will soon come out in the enterprise. Industry experts believe that if the technology can be successfully applied, it will be a major breakthrough in China's coal mine gas disaster from passive prevention to active suppression of explosion. At the end of April, at the 9th "Taiyuan Coal Industry Technology and Equipment Exhibition", Taiyuan Mining Group and Shanxi Orchid Hans Company reached a technical cooperation intention to co-develop a new type of coal shearer that actively suppresses gas explosion. In accordance with the agreement, the two sides have formed a professional group to step up development. It is estimated that in early September this year, China's first gas explosion-suppression shearer will be successfully off-line in Taiyuan Mining Group. It is reported that this ultra-high-speed flame retardant technology, the earliest use of military products in South Africa. Last December, Shanxi Orchid Hans Company introduced this high-tech, in our country won the "mining product safety mark certificate."

IECEx Approved Coriolis Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.


The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.


The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
