1. Product overview
AR3411The pressure transmitter adopts the diffused silicon pressure sensitive element as the measuring component. The measuring signal is amplified by the special signal conditioning circuit and converted into various standard signals. The pressure and electrical signal are in linear correspondence. It can realize the accurate measurement of the field pressure.
The explosion-proof type meets the requirements of gb3836.1-2010 and gb3836.4-2010, and the explosion-proof sign is ExiaIICT6 GA.
The explosion-proof type meets the requirements of gb3836.1-2010 and gb3836.2-2010, and the explosion-proof mark is exdiict6 GB.
The product adopts all stainless steel packaging structure, with stable and reliable performance, and is suitable for pressure measurement of process control in petroleum, chemical, metallurgy, electric power, hydrogeology and other industries.
