เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น PSX2
คุณลักษณะ
The explosion-proof filling level or point level sensor has excellent properties, is hermetically tight and very robust in its stainless steel housing. Appropriate protective circuits guarantee inverse-polarity protection and overvoltage resistance. The probe is of long-term stability and simple to operate
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.
