Features
The SS152 series piezoresistive pressure transducers are designed to measure low-corrosive liquids. They work well with seawater, domestic sewage, weak acids, and weak bases.
The stainless steel that comes into contact with the medium is coated with PTFE. This coating resists many corrosive substances. It can handle acids, alkalis, salts, and organic solvents.
This boosts the corrosion resistance of stainless steel 316L in tough environments. It’s ideal for high-corrosion resistance in chemical equipment. The transducers’ pressure ranges from 35 kPa to 10 MPa.
