Industrial Humidity and Temperature Sensor for Permanent High-Humidity and Polluted Environment

EE33

Important information:

Please note that the EE33 has been discontinued. Do not use/ specify EE33 for new projects, it is replaced by HTS801 humidity and temperature sensor.

 

EE33 is optimised for reliable humidity and temperature measurement in applications with temporary condensation, permanent high humidity or chemical exposure. Condensation on the monolithic humidity sensor and the filter cap is prevented by controlled heating of the sensor.

The measuring principle of EE33-T17 with separate humidity and temperature probes and dual heating enables precise continuous measurement even at permanent high humidity.

The remote probe can be employed up to 180°C (356°F) and the pressure tight version up to 100 bar. The three-part design of rugged enclosure in polycarbonate or aluminium allows easy mounting and replacement. The measurands are available on two analogue outputs and a serial interface.

An optional relay output can be used for alarms and process control. The proprietary coating protects the sensors and their leads against corrosive and electrically conductive pollution.

Typical applications

  • Pharmaceutical and food industry
  • Driers for ceramics, wood, concrete, polyester etc.
  • Greenhouses, mushroom farms
  • High-humidity storage rooms
  • Climate, test and curing chambers
  • Meteorology
  • Fuel cell test benches

Humidity Monitoring for Efficient Fuel Cells

Fuel cell technology is an environmentally friendly, emission-free alternative to conventional methods of generating electricity. Balancing the humidity and temperature inside the cell is crucial to the performance and lifetime of polymer electrolyte membrane (PEM) fuel cells

The EE33-T17 is ideal for test benches designed to measure the moisture content of the injected reaction gases (H2, O2) directly downstream of the humidifier. Due to its excellent measuring performance in the high humidity range (>85% RH), the sensor provides exact measured values, enabling optimum management of the moisture content.
