Introduction
This chapter provides basic information about device. Before starting please read
this manual carefully.
The Web Sensor devices are designed for measurement of temperature, relative humidity,
atmospheric pressure or carbon dioxide concentration of air without aggressive substances.
Measured quantities are according device type. Devices with relative humidity measurement
can show one of computed quantities: dew point temperature, absolute humidity, specific
humidity, mixing ratio and specific enthalpy. Temperature units are °C or °F. Pressure units
are hPa, PSI, inHg, mBar, oz/in2, mmHg, inH2O and kPa. Communication interface of Web
Sensors is Ethernet. Web Sensor can be powered from external power supply adapter or by
power over Ethernet –PoE. Device types:

Models marked TxxxxZ are custom-specified devices. Description of these devices is not
included in this manual.
A multiple point CO2and temperature adjustment procedure leads to excellent CO2
measurement accuracy over the entire temperature working range; this is a must for process
control and outdoor applications. The dual wavelength NDIR CO2sensing procedure
compensates automatically for ageing effects. The CO2module is highly resistant to pollution
and offers maintenance free operation and outstanding long term stability.
Measured values can be read in „SLOW mode“ (filtered, averaged) or in „FAST mode“
(current values without averaging). „SLOW mode“ has advantages in applications like
climate control because of filtering short time peaks. As an example exhaled air from
an employee passing the sensor could affect the climate control negatively with a short
response time because the control would trigger a change of the ventilation based on this
one-time measurement. On the contrary in „FAST mode“ no software filter is used for

calculating the output value. This fact adds a noise of typ. ±30ppm which has to be
considered in terms of accuracy. Of principle measurement is the measured value of CO2
concentration depends on the value of air pressure - altitude at the installation site. For this
reason, it is suitable for accurate measurement to set the altitude of the installation site.
After power up of the device starts internal test. During this time (about 20s) LCD display
shows (----) instead of CO2concentration value. Web pages show n/a.

Device description and important notices
This chapter contains information about basic features. Also there are important
notices concerning to functional safety.
Measured values can be displayed on LCD display or can be read using an Ethernet
connection. The following formats are supported:
•Web pages
•Current values in XML and JSON format
•Modbus TCP protocol
•SNMPv1 protocol
•SOAP protocol
The device can also be used to check measured values and if the limit is exceeded, device
sends warning messages. Possible ways to sending warning messages:
•Sending e-mails up to 3 e-mail addresses
•Sending SNMP traps up to 3 configurable IP addresses
•Displaying the alarm status on web page
•Sending messages to Syslog server
The device setup can be made by the TSensor software or web interface. TSensor software
can be free downloaded from the manufacturer’s website. Latest firmware can be obtained
from the technical support. Do not upload to your device firmware which is not designed
for it. Unsupported firmware can damage your device.
If you want to use PoE, you must use PoE switch compatible with IEEE 802.3af standard.
Reliability of warning messages delivering (e-mail, trap, syslog), depends on
actual availability of necessary network services. The device should not be used
for critical applications, where malfunction could cause to injury or loss of
human life. For highly reliable systems, redundancy is essential. For more
information please see standard IEC 61508 and IEC 61511.
Never connect the device directly to the Internet. If it is necessary connect the
device to the Internet, properly configured firewall must be used. Firewall can
be partially replaced by the NAT.
