Humidity and Temperature Module for OEM Applications


The EE99-1 employs high-end E+E humidity sensing elements manufactured in state-of-the-art thin film technology, which are the prerequisite for outstanding measurement accuracy.

Humidity and temperature module EE99-1

With a working range from -50 °C (-94 °F) up to 180 °C (356 °F) and various probe and cable lengths the EE99-1 module is suitable for a wide range of applications.

The E+E proprietary coating protects the sensing elements against corrosive and electrically conductive pollution, which leads to excellent long-term stability even in harsh environment.

What is the difference between a 2 wire and a 3 wire current output?

Transmitter with “two-wires” technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology “three-wires” the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
