เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น SMO
คุณลักษณะ
Thanks to its stainless steel membrane and to its semiconductor thin-film technology, the transducer has excellent properties regarding its long-term stability, medium compatibility and pressure peaks that suggest its advantageous use in most industrial applications. Also its robustness even in very rugged ambient conditions in the field of mobile hydraulics is guaranteed by its welded stainless steel housing. The EMC properties of the SMO series permit its application also in sophisticated environments. Its ratiometric model has been successfully tested up to 300V/m. ADZ NAGANO GmbH has been certified acc. to ISO/TS 16949, among others
- Measuring ranges 0...4 bar and to 0...4000 bar
- Output signals 4-20 mA; 1-5 V; 0-10 V; 0.5-4.5 V ratiometric
- Temperature range of media up to 150°C
- Shock and vibration resistance > 1000 g shock, > 30 g vibration
- Protection class IP67 (special version up to IP69K)
- Compact and rugged model in stainless steel
- High flexibility for options thanks to modular design
- Highly reliable

| IP system of protection | The IP system of protection as specified in the data sheets generally applies, with their mating plug connected. Relation pressure transmitters require a ventilated mating plug and/or cable to allow for pressure compensation. From a pressure range of 60bar, ventilated mating plug and/or cable is not necessarily required. | |||||||||
