Pump for use in analytical laboratories
With the Ecodry series, Leybold
offers a clean, silent, compact
and low-maintenance pump for
use in analytical or research laboratories.
This pump class lies
exactly in the transition area between
small laboratory devices
and large machines. However,
the most significant innovation
is undoubtedly the reduction of
the noise level. The Ecodry plus
was developed exactly in line
with the requirements of systems
such as mass spectrometers
and electron microscopes. It is
therefore also suitable for use in
large accelerators, because there
is no contamination by dust or
oil. It offers users a high degree
of comfort, pumping speed performance
and flexibility.
Equipped with two flexible interfaces,
the pump can also be
remote-controlled. When used
in commercial analysis systems,
it is often integrated into the
plant control system and can be
started, stopped, varied in speed
and also monitored as required.

Multifunction four-wire transmitter
The Jumo dTrans T06 Ex multifunction
four-wire transmitter in
a mounting rail case is suitable
for use in challenging SIL and Ex
applications. Its measurement
input features 22-bit resolution
with selectable noise suppression
and is extremely precise. The SIL
option fulfills the requirements
of SIL2/SIL3 according to DIN
EN 61508 and PL c/PL d according
to DIN EN ISO 13849. The
dTrans T06 Ex also meets the
Atex and IECEx requirements up
to zone 0.
A particularly high galvanic isolation
guarantees excellent signal

stability, even when measuring
conditions are difficult. Reliable
SIL configuration is facilitated by
an easy-to-use setup programme.
The device can be used with RTD
temperature probes, thermo -
couples, resistance transmitters,
as well as voltage and current
signals. It converts the input
signal into an output signal
(0(2)...10 V or 0(4)...20 mA).
The compact mounting rail case,
which has a design width of just
22.5 mm, and the encoded plugin
terminals enable the device to
be quickly installed into control
cabinets. In addition, the device
can be reliably replaced when
performing calibration and
maintenance work. All the important
information regarding
the transmitter can be queried
and visualised via an RS485 interface.
