• • • Overview of Product • • •
MS350 anti - corrosive pressure transducer adopts German HELM made high – performance anti – corrosive tantalum membrane force – sensitive chip, supported with high – accuracy electronic element, and assembling with strict process flow. This series of product features strong corrosive resistance, wear resistance etc, which has very well solved the problems for pressure measurement of strong – and weak – corrosive gas or liquid under special domestic application.
• • • Features of Product • • •
1. Designed with tantalum membrane pressure resistant type chip, with very strong corrosive resistance
2. Impact – and vibration – proof, wear resistance
3. High accuracy: 0.25% FS 0.4% FS
4. Good stability: ≤0.2% FS / year, ≤0.2% FS / °C
5. Without production process pollution; without force transmission filling liquid
6. The enclosure may be made of PVC, titanium alloy or PTFE, depending on the customer’s corrosion of medium.
• • • Application of Product • • •
This series of pressure transducer may widely be used for such fields as petroleum, chemical, metallurgical, electric power, protection of environment etc to automatically measure and control the gauge pressure, absolute pressure, and negative pressure of corrosive gas, liquid, and vapor.
