EE33 Humidity / Temperature Sensor for High Humidity and Chemical Applications
1.2.4 Intended Use
The EE33 sensors are designed to meet the highest demands of stable and highly precise
measurements of relative humidity (RH) and temperature (T) under the most challenging conditions.
EE33 is suitable for a wide range of applications from -40 °C
(-112 °F)
up to 180 °C
(356 °F)
and 100 bar
(1 450 psi)
.
With different heating modes of the monolithic RH and T sensing element EE33 can be perfectly
tailored to the specific needs of each measuring task.
The device may only be powered as decried in this manual.
The use of the EE33 in any other way than described in this manual bears a safety risk for people and
the entire measurement installation and is therefore not allowed.
The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation,
and maintenance of the equipment.
In order to avoid damage to the instrument or health hazards, the measuring equipment must never be
manipulated with tools that are not specifically described in this manual.
The sensor may only be utilized in accordance with the conditions defined in the technical data.
Otherwise, measurement inaccuracies will occur and equipment failures cannot be ruled out.
The steps recommended by the manufacturer for installation, inspections and maintenance work must
be observed and carried out for the safety of the user and for the fu
nctio
nality of the equipment.
Unauthorized product modification leads to loss of all warranty claims. This may be accomplished only
with an explicit permission of E+E Elektronik!
1.2.5 Mounting, Start-up and Operation
The EE33 humidity and temperature
sensor has been produced under state of the art manufacturing
conditions, has been thoroughly tested and has left the factory after fulfilling all safety criteria. The
manufacturer has taken all precautions to ensure safe operation of the device. The user must ensure
that the device is set up and installed in a manner that does not have a negative effect on its safe
use. The user is responsible for observing all applicable safety guidelines, local and international, with
respect to safe installation and operation on the device. This user manual contains information and
warnings that must be observed by the user in order to ensure safe operation.
Mounting, start-up, operation and maintenance of the device may be performed by qualified staff
only. Such staff must be authorized by the operator of the facility to carry out the mentioned activities.
The qualified staff must have read and understood this user manual and must follow the instructions
contained within.
All process and electrical connections shall be thoroughly checked by authorized staff before putting
the device into operation.
Do not install or start-up a device supposed to be faulty. Make sure that such devices are not
accidentally used by marking them clearly as faulty.
A faulty device may only be investigated and possibly repaired by qualified, trained and authorized
staff. If the fault cannot be fixed, the device shall be removed from the process.
Service operations other than described in this user manual may only be performed by the
manufacturer.
1.3 Environmental Aspects
Products from E+E Elektronik are developed and manufactured in compliance with all relevant
environmental protection requirements. Please observe local regulations for the device disposal.
For disposal, the individual components of the device must be separated according to local recycling
regulations. The electronics shall be disposed of correctly as electronics waste.
2 ESD Protection
The sensing elements and the circuit board are ESD (electrostatic discharge) sensitive components of
the device and must be handled as such. The failure to do so may damage the device by electrostatic
discharges when touching exposed sensitive components.
