เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น TPSI
คุณลักษณะ
This intelligent solution combines two transmitters which are capable of measuring pressure and temperature at the same time and independently. This multi-functional transmitter has excellent characteristics for its stainless steel membrane and semi-conductor thin-film technology. The stainless steel membrane is absolutely vacuum-tight, extremely burst-proof and applicable with all standard media used in hydraulics, pneumatics, etc. as far as they are compatible with stainless steel. Its robust design guarantees high reliability also in rugged environments. The temperature is measured by means of an internal temperature sensor
- Pressure measuring ranges 0...1 bar to 0…1.000 bar
- Temperature measuring range -50°C to +150°C
- Output signals for pressure 0…10 V, 0.5…4.5 V for temperature 0.25…4.75 V
- No internal transmission media
- Precision class 0.5 %
- Highly reliable
- Protection class IP67

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