Industrial processes place stringent demands on instrumentation. Extreme ambient conditions, aggressive media, chemically intensive cleaning and the need for accurate, fail-safe data are common. Conventional sensors soon reach their limits because of condensation, corrosion, temperature extremes or labour-intensive maintenance. This is where the HTS401 excels.
With a robust and intelligent protection concept that combines the E+E sensor coating with connection encapsulation, the HTS401 remains ready for service even under severe stress. The Automatic Recovery function (ARC) protects the sensing elements against adverse chemical influences. In the event of condensation risk, the Condensation Guard (CG) intervenes before measurement performance is affected.
