Intrinsically Safe Pressure Transmitter for Industrial Use

Its widely ranging industrial applications are guaranteed by its high precision and robust and compact design. These Intrinsically Safe Pressure Transmitters are available in combination of various mechanical and electrical connections.

The Intrinsically Safe Pressure Transmitter in field housing has been designed for application in rugged environments. Due to its stainless-steel thin-film measuring cell, this pressure transducer features excellent properties. It is extremely 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 an option to 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

 

SKU: SMX2 Category:

Due to its stainless steel diaphragm and semiconductor thin-film technology, the explosion-proof pressure transmitter has excellent properties and can be applied in hydraulics, pneumatics, environmental engineering and more with all standard media compatible with stainless steel.
