The ultrasonic transducers of the new hps+ sensors are now fitted out - as standard - with a teflon film It is sealed with a FFKM O-ring against the housing made of 1.4571 stainless steel or PVDF. This ensures a high degree of resistance to aggressive media.
The hps+ sensors can be used for filling level measurement in tanks up to a 6 bar positive pressure. Pressure-tight installation in a tank is undertaken by means of a 1" threaded flange or a 2" one in the case of hps+340.
Chemical resistance and seal tightness was tested through being stored over cellulose thinner and 1,000,000 alternating pressure stresses. Cellulose thinner is extremely corrosive and has a high rate of penetration.
