High Temperature Pressure Transmitters – Thin-Film Solution
EST380 is sputter thin film type pressure transmitter, that features heat-resistance (-40~150℃ or even 200℃), wide range and high accuracy (0.1%-0.25%/FS). It includes protective circuits that feature pressure peak damping and load-dump protection, and it is resistant to EMV stability reverse voltage. It is calibrated electronically, ensuring its readings have minimal total error and are reliable over time.
For EST380, the hermetically sealed thin film measuring cell contributes to its long-term resistance to leakage and stability (no oil fluid filled). Its stainless-steel membrane, which is vacuum-sealed and highly burst-resistant, suits all standard media in various fields (hydraulics, pneumatics, environmental and process technologies, semi-conductor technologies, and automotive engineering), given their compatibility with stainless steel.
It chiefly serves standard applications in hydraulics and other sectors. Given its high accuracy (0.1% | 0.25% | 0.5%) and robust structure (no O-Ring), compact design (short size), it is versatile for many industrial uses. You can select from a different pressure range of pressure transmitters (0-4bar; 0-10bar, 0-500bar, 0-1000bar, 0-2000bar or more) thanks to the combination of different mechanical and electronic connections.
