FlexTop 2202 Temperature Transmitter 4...20 mA transmitter for Pt100 sensors 2-, 3- or 4-wire sensors Accuracy better than 0.25C Sensor offset correction Automatic/configurable cable resistance compensation (2-wire) Sensor error detection 2-way configuration Configurable damping and status indication Engineering unit C or F PC datalogging Excellent temperature stability Ex ia IIC T5/T6, ATEX II 1G Description FlexTop 2202 is a 4...20 mA loop-powered transmitter for Pt100 sen- The Flex-Program has a datalogging facility enabling the user to moni- sors. tor measuring results or calibrate the measuring setup. Either 2-, 3- or 4-wire sensors can be used. For 2-wire sensors an FlexTop 2202 is embedded in silicone which makes it resistant to automatic balancing of the sensor cable resistance is possible with humid environments. shorted sensor cable. The cable resistance can be manually config- FlexTop 2202, fitting into the DIN B housing, has a 6 mm center hole ured as well. for quick sensor replacement. The spring loaded mounting screws Using a PC, the Windows-based Flex-Program and a FlexProgrammer ensure a safe fastening even in vibrating environments. configuring unit, the following parameters can be configured via the output connectors (2-way communication): TAG no., number of wires, cable resistance, error detection level, measuring range/unit, damping, offset and status indication. www.baumerprocess.com Data Sheet 2202-1 Design and specifications 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: 0.1% of span Humidity < 98% RH, cond.
