company news about What is the Role of PSS and ABS Materials in Chemical-Resistant Conductivity Sensors?

In chemical processing and laboratory environments, conductivity sensors are often exposed to substances that would quickly degrade metal components. PSS (Polysulfone) and ABS are high-performance plastics that offer excellent resistance to a wide variety of acids, alkalis, and salts. PSS, in particular, is known for its thermal stability, allowing it to be used in temperature ranges up to 120°C or even 135°C, which is unusual for plastic materials. This makes PSS sensors an excellent choice for chemical reactors where both heat and corrosion resistance are needed.

These plastic-housed sensors are usually paired with a single-channel analog controller capable of measuring a wide range of ionic concentrations, from 0.5 to 200μS/cm to 0 to 10mS/cm. The controller's ability to display TDS and salinity allows lab technicians to monitor chemical reactions or the concentration of cleaning solutions in real-time. Despite being made of plastic, these sensors can be engineered to handle moderate pressures, with many models rated for 0 to 4 bar or 0 to 10 bar. By choosing the right plastic housing, facilities can reduce the cost of their monitoring equipment while ensuring that their conductivity and resistivity measurements remain accurate even in the presence of aggressive chemical reagents.
