One-channel, two-channel
and four-channel thermometer
for external probes
These devices measure one, two or up to four
temperatures from external probes of the Pt1000 series.
The response to a temperature change depends on the
connected probe design. As a rule, this model is few
times faster than that using the internal sensor. It is often
used to monitor locations where the device itself is not
directly in the measuring area and only probes are in. The
maximum length of each probe lead should not exceed
15 m. It is recommended to use shielded cables. To
maintain the IP rating, the unused probe connectors
should be provided with a supplied closing cap.
The
battery in the device cannot be charged.
The models U0111, U0121, U0141 have a high degree
of IP67 protection and probes with the connector
(Pt1000/E) can be connected to it. In order to maintain
the degree of protection, it is necessary to provide
unused connectors with the supplied cover.
The model U0141T has a low degree of protection
IP20. The connectorless probes Pt1000/0 series are
intended to this model. The device has not a protection
against the ingress of water or dust. Do not use device
at places where such conditions can be expected.
The probes are connected to the pluggable terminal
block.
Connection:
The procedure for connecting the wires to the terminals
can be found in
Annex 4 .
