Description
FlexTop 2202 is a 4...20 mA loop-powered transmitter for Pt100 sensors.
The Flex-Program has a datalogging facility enabling the user to monitor measuring results or calibrate the measuring setup.
Either 2-, 3- or 4-wire sensors can be used. For 2-wire sensors an
automatic balancing of the sensor cable resistance is possible with
shorted sensor cable. The cable resistance can be manually configured as well.
FlexTop 2202 is embedded in silicone which makes it resistant to
humid environments.
Using a PC, the Windows-based Flex-Program and a FlexProgrammer
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.

FlexTop 2202, fitting into the DIN B housing, has a 6 mm center hole
for quick sensor replacement. The spring loaded mounting screws
ensure a safe fastening even in vibrating environments.
