เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น SMX2FG
คุณลักษณะ
The SMX2 in field housing has been designed for application in rugged environments. Thanks to its stainless-steel thin-film measuring cell, this pressure transducer features excellent properties, it isextremely robust, fully welded and without any hydraulic transmission media. The measuring range can be freely positioned at a ratio of 4:1 in the upper end range. There is also thepossibility to freely select the response time. Both parameters can be managed with the help of a service box, including software. Further advantages of this model consist in the transmitter being able to be adjusted or calibrated even without having to separate it from the measuring loop. Tests can be performed within the system by means of a loop generator (pressure simulator) inside the transmitter
Zone 0 An area where an explosive atmosphere of a mix of air and combustible gases, vapours or sprays is permanently, over long periods or frequently prevails.
Zone 1 An area where an explosive atmosphere of a mix of combustible materials in the form of gas, vapour or spray with air occurs occasionally in normal operation.
Safety Note: When fitting, commissioning and operating this pressure transmitter, please observe relevant national safety regulations by all means.
