Features

The E+E proprietary sensor coating is a protective layer applied to the sensing elements, their leads and soldering

points. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive

environment (salts, off-shore applications). Additionally, it improves the long term stability in dusty, dirty or oily applications

by preventing stray impedance caused by deposits on the active sensor surface or on the electrical connections.

Protective Sensor Coating

Automatic ReCovery (ARC) is available for all HTS801 types and is used to remove chemical pollution and thus eliminate

possible drift effects of the RH / T sensing element. This is achieved with an intense heating of the sensing element. The

function can be perfectly tailored to the application requirements being triggered:

▪ manually via PCS10 or display and push-buttons,

▪ by a certain cyclic time interval configurable via PCS10,

▪ using RS485 or Ethernet with Modbus commands, or

▪ using the ARC module option (AM1).

Condensation Guard (CG)

HTS801 sensors with Condensation Guard (CG) are designed for applications with variable humidity over the full range

0...100 %RH where condensation may occur for a short time. The CG protects the RH / T sensing element by targeted

heating and prevents temporary condensation and its negative effects on the measurement results. The CG heating is

triggered by a predefined RH setpoint factory set via ordering guide. The setpoint is configurable with PCS10 and display

and push buttons.

High Humidity Guard (H2G)

HTS801 sensors with High Humidity Guard (H2G) enable accurate RH measurement even in permanent high humidity and

condensing conditions. Continuous, adaptive heating of the sensing element and of the probe body (dual heating system)

prevents drift effects and condensation on the sensor element. The monolithic construction of the sensing element enables

fast RH response times under condensing conditions.

Type-specific Operating Modes

The HTS801 with PC7 option (see ordering guide) features the intelligent pluggable rapidX probe, which enables a plug-

and-play probe exchange. Any HTS801 rapidX Smart Probe automatically uploads its specific parameters upon connecting

it to the HTS801 electronics and can be replaced even during operation without any configuration, adjustment or

calibration. This is particularly useful for excluding down time and its corresponding costs in harsh industrial environment,

where the probe can get occasionally damaged.
