E+E EE33 Humidity/Temperature Transmitter User Manual
This manual provides detailed instructions for installing, configuring, and maintaining the E+E EE33 humidity/temperature transmitter. It covers various models (C, D, E, I, J, K) with different sensing probe capabilities, electrical connections, and optional modules. The transmitter features a heated measurement cell for reliable operation in humid or chemically polluted environments. It includes sections on calibration, automatic recovery (ARC) for chemical pollution or condensation, and safety guidelines for handling.
The manual also explains operating modes such as automatic recovery, warming, and heating time settings, and how to use optional modules like alarm or Ethernet modules. It includes technical data, maintenance procedures, and environmental considerations for proper disposal.

Questions answered in these manuals
How does the sensor prevent condensation?
The sensor uses a Condensation Prevention heating mode that heats the sensing element when a configurable RH setpoint is reached.
What enclosure materials are available for the EE33?
The EE33 is offered in a polycarbonate housing (IP65/NEMA 4) or a metal (AlSi9Cu3) housing with the same protection rating.
What is the Automatic ReCover (ARC) function?
It heats the measurement cell to evaporate chemical residue or temporary condensation, helping to minimize distorted readings during calibration.
What are the different models available?
Models C, D, E, I, J, and K, each with different sensing probe capabilities and pressure ratings up to 100bar (1450psi) for model I.
