Pressure Transmitter รุ่น TPSE
คุณลักษณะ
This intelligent solution combines two transmitters which are capable of measuring pressure and temperature at the same time and independently. The TPSE has excellent characteristics for its stainless steel membrane and semiconductor thin-film technology. The stainless steel membrane is absolutely vacuumtight, 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. Installing an external temperature sensor will enable quick adjustment times, with custom-made length of the temperature sensor to be installed.
- Pressure measuring ranges 0...4 bar to 0…600 bar
- Temperature measuring range -50°C to +200°C
- Output signals for pressure 4…20 mA, 0…10 V for temperature 4…20 mA
- No internal transmission media
- Precision class 0.5 %
- Highly reliable
- Protection class IP67

| CE-conformity | The IP system of protection as specified in the data sheets generally applies, with their mating plug connectrd. Relative perssure transmitters usually require a ventilated mating plug and/or cable to allow for pressure compensation. From a pressure range of 60 bar, a ventilated mating plug and/or cable is not necessrily required. | |||||
