JUMO dTRANS CR 02
Transmitter/controller for conductivity, TDS,
resistance, standard signals and temperature
Brief description
The JUMO dTRANS CR 02 is a compact, modular instrument. It is highly flexible (for example
3 slots for optional boards) and capable of performing a wide range of tasks. The main input of
the JUMO dTRANS CR 02 is used for sensors for measuring electrolytic conductivity, specific
resistance, or the TDS value. Both conductive two-electrode and four-electrode cells can be
connected to the instrument. The second analog input (compensation input) is designed for
resistance thermometers Pt100 and Pt1000, NTC/PTC or standard signals 0(4) to 20 mA or
0 to 10 V. The two binary inputs can be used either as initiators for actions (e.g. HOLD, keyboard
inhibit) or when connecting pulse generators (for example impeller sensors) for flow-rate
measurement. The high-contrast graphic display allows for several options including display of
input signal with numbers or as bar graph. Parameters are displayed in plain text for easily
comprehensible and reliable operation.
The JUMO dTRANS CR 02 can be used as a two-point or three-point controller, a three-point
modulating controller, or as a continuous controller. All controller outputs can be configured to
P, PI, PD or PID action. The software for the controllers includes parameter set selection, a math
module and more.
A setup program is available for convenient configuration via PC. The instrument can be
integrated into a data network by means of an RS422/485 or PROFIBUS-DP interface. Screw
terminals on the back are used for the electrical connection.
Some applications:
Industrial and process water.
Drinking and well water.
Pure, ultra-pure and pharmaceutical water (e.g. as per USP, Ph. Eur., WFI).
Cleaning processes in pharmaceutical applications (four-electrode cells in conjunction with
measuring range selection).
