เซนเซอร์แปลงความดัน Pressure Transmitter
รุ่น SKE
คุณลักษณะ
The SKE is a high-temperature pressure transducer with remote electronics. This makes the sensor fit for use in temperatures of up to 200°C. The electronics are remotely connected to the pressure cell by Teflon cable, allowing it to be placed in lowertemperature environments. This pressure transducer features excellent properties thanks to its stainless-steel membrane and semi-conductor thin-film technology. It may also come as a titanium version. The stainless-steel membrane is entirely vacuum-tight, extremely burstproof and can be used with all standard media, as far as they are compatible with stainless steel. Furthermore, its modular design offers a multitude of signaling, threading and connecting options. And on top of that, special customized calibration in a desired measuring range is available on request.
