E+E EE310 Specifications

EE310

High-End Humidity and Temperature Sensor

for Industrial Applications

The EE310 is optimized for best reliability in industrial applications up to
180 °C (356 °F) and 20 bar (290 psi). In addition to highly accurate measurement
of the relative humidity (RH) and temperature (T), the device calculates all other
humidity related parameters.

Measurement Performance

The EE310 employs high-end E+E humidity sensing elements manufactured in

state-of-the-art thin lm technology, which are the prerequisite for outstanding

measurement accuracy.

Long-Term Stability

The E+E proprietary coating protects the sensing elements against corrosive

and electrically conductive pollution, which leads to outstanding long-term
stability even in harsh environment. With the appropriate choice of lter cap,

the EE310 tackles even challenging industrial applications.

Versatility

The EE310 is available for wall or duct mount as well as with remote probe. It
features an IP65 / NEMA 4 polycarbonate or stainless steel enclosure which

facilitates installation and maintenance. The enclosure can accommodate a
100…240 V AC supply unit or various interface modules.

Display and Outputs

The measured data is available on two analogue outputs, on the RS485

(Modbus RTU) or Ethernet-PoE (Modbus TCP) interface and on the alarm
(relay) outputs.

The TFT colour display shows simultaneously up to four measurands and

offers extensive setup and diagnosis features. The data logging function saves up to 20000 measured values for each

physical quantity. The logged data can be displayed graphically directly on the device or easily downloaded over the
USB interface.

Congurable and Adjustable

The conguration and the RH and T adjustment of the EE310 can be performed either using the display and the push
buttons or with the free EE-PCS Product Conguration Software via the USB interface.

Protective sensor coating (option C1)

The E+E proprietary sensor coating is a protective layer applied to the active surface and leads of the sensing elements.
The coating substantially extends the lifetime and the measurement performance of the E+E sensor in corrosive environment
(salts, off-shore applications). Additionally, it improves the sensor’s long term stability in dusty, dirty or oily applications by
preventing stray impedances caused by deposits on the active sensor surface.
