QuantaDat / nSens
Measuring Humidity Transmitter
with multi-sensor technology
For remote digital sensors in process applications
QuantaDat transmitter
Modular transmitter used as display and signal output unit with 4 sensor channels. The
sensors are recognised automatically and the measuring channels can be assigned and set
up within the configuration menu . The integral processor allows the display and output of
calculated climatic parameters. An RS-485 interface is built-in as standard and BUS modules
can be assembled optionally. The QuantaDat transmitter is also available in a version with
two additional integrated relay switches.
• Graphical display with LED backlight
• Menu navigation using front keypad with 3 buttons
• Modular configurable (e.g. with BUS modules)
• Several sensor channels active at once
• 4 scalable and adjustable analogue outputs
• Simulation of fixed measurement values (override)
• Integrated climatic parameter processor
• Password protection for all settings
Art. no. 2601087
• Permanent device function control

Electrical installation
Recommended wiring installation:
Power supply
Cable specification
Single-cable of 0.5...0.75 mm2 (22 ... 18 AWG) with PVC isolation
or equivalent 2-fold cord cable.
Signal outputs
Single cable of 0.25...0.5 mm2 (24 ... 20 AWG) twisted with screen
& PVC isolation or equivalent 2/4/6/8 multi-core cable.
RS-485 interface
Relay contacts
1 twisted pair + C(GND) connection recommended, screened
Cable dimensions dependent on the switching power needed

acc. to EIA-485
only for version
with relay
Note: cable specifications depend on the installation and have to be defined by the designer
or installer.
EMC: if environmental conditions vary from the standards (see page 2) it is recommended to
take the following measures:
•
•
•
•
Wires emitting interference must be separated from measurement and analysis units
Parallel guidance of measurement- and electrical power-cables should be avoided
Measurement cables must be screened to ground earth
Cables not screened should be in twisted pairs and should be kept as short as possible
