FlexTemp 2301 Temperature Transmitter 4...20 mA transmitter for Pt100 sensors 2-, 3- or 4-wire sensors Accuracy better than 0.25C Sensor offset correction Automatic/con gurable cable resistance compensation (2-wire) Sensor error detection 2-way con guration (Windows) Con gurable damping and status indication Engineering unit C or F PC datalogging Description FlexTemp 2301 is a 4...20 mA loop-powered transmitter for Pt100 Using a PC, the Windows-based FlexProgram software and a FlexPro- sensors. grammer con guring unit, the following parameters can be con gured via the output connectors: TAG no., number of wires, cable resistance, Either 2-, 3- or 4-wire sensors can be used. For 2-wire sensors an error detection level, measuring range/unit, damping, offset and status automatic balancing of the sensor cable resistance is possible with indication. shorted sensor cable. The cable resistance can be manually con g- ured as well. The FlexProgram has a datalogging facility enabling the user to moni- tor measuring results or calibrate the measuring setup. www.baumerprocess.com Data Sheet 2301-1 Design and speci cations subject to change without notice Page 1 Technical Data Input Environmental conditions Accuracy Operating temperature -40...85C Span < 250C: < 0.25C 2 Storage temperature -55...90C Span > 250C: 0.25% of span Humidity < 90% RH (IEC 68-2-38) Sample time < 0.7 sec.
