Introduction:
Smart differential pressure transmitter is a new-type intelligent instrument researched and developed by
our company along with some internal companies under international advanced technology.
The meter has temperature and non linearity compensation under micro processing technology,
improved meter measurement accuracy and temperature feature,expnded range ration,added the function
of intelligent configuration,further meet the reliable and stable requirement for industrial field.Keycomponent
and parts areimported and strict test is done before delivery.The meter has advanced design principle,reliable
product quality, variety,Simple installation and usage etc features.
