Humidity transmitter with Ethernet – Your benefits at a glance
Ethernet finally also for humidity transmitters
Testo, as the first supplier worldwide of humidity measurement
technology, offers an Ethernet interface for humidity transmitters.
Now, parallel to the use of analog outputs for regulation purposes,
integrated measurement data monitoring from the the field to
management level (e.g. data from production available in the office) is
made possible easily, efficiently and at a competitive price.
Ethernet is prevalent in almost all office networks so that installation
work is kept to a minimum when the humidity transmitter is
connected to the network structures already in existence.
The new testo 6651 and testo 6681 humidity transmitter generation is
designed for process monitoring in HVAC, process and compressed
air technology. With solutions for highest accuracy as well as for
special applications (high humidity, H 2
O 2
sterilisation processes, trace
humidity applications, etc.) unrivalled cutting edge technology is
available for measuring humidity.
Developed for practical use
The Ethernet module is an “intermediate layer” (sandwich design)
which is already built into the testo 6651 and 6681 transmitters in the
factory. It can also be subsequently easily and quickly retrofitted on
site.
Two LEDs signal the status of the power and LAN connection to the
system operator responsible.
By using an Ethernet plug suitable for industry, IP65 housing
protection can be guaranteed so that the transmitter withstands the
sometimes tough and demanding conditions of industrial processes.

Process reliability and time saved by measurement data monitoring
Networking transmitters using Ethernet provides considerable benefits in a number of applications such as for monitoring laboratories,
warehouses, production rooms, cleanrooms or drying systems. In addition to transmitting the readings signals by analog outputs to a control
system, measurement data can also be simultaneously recorded, documented and visualised using Ethernet. If necessary, it is also possible to
alert the person responsible for the process.
Easy to install
High transmission speed
Consistency of data
=> High accuracy level since
no signal conversion is
needed
