Product temperature monitoring connection
LK(U)v, LCv, LK(U)exv, LG(U)ex and LGT laboratory appliances with Comfort-Controller
Interface for optional NTC product temperature probe
All LK(U)v, LCv, LK(U)exv, LG(U)ex and LGT models have an integrated interface for connecting an optional
available NTC product temperature probe to the comfort controller. The controller can be set to display either
the internal air temperature, as registered by the air probe, or the temperature registered by the product
probe. Depending on this selection the temperature alarm limits are related either to the air probe or to
the product probe. In addition the product temperature can be monitored on an external documentation
system via the RS 485 interface.
Whereas the air probe is in a fixed position, the product probe will be located by the user, e.g. in a phial or
in a measurement package in order to simulate a product temperature.
The product temperature probe is water resistant and resistant to corrosion (IP 68 and AISI 316). It complies
with NSF standards.
Due to possible tolerances of the product temperature probe the temperature displayed can differ from
the product probe temperature. Using the calibration function, the temperature displayed can be aligned
with the product probe temperature. The correction value for the compensation of the differences can be
adjusted in 0,1 °C steps.
