Description
FlexTemp 2321 is a 4...20 mA loop-powered, configurable universal
transmitter with galvanic isolation between input and output. The input
can be configured for RTD or T/C sensors, resistance, current or voltage signals.
Either 2-, 3- or 4-wire connection can be selected for the resistance
input. The built-in temperature sensor or a remote Pt100 sensor can
be used to compensate for "cold junction" (CJC) if thermocouples are
connected.

Design and specifications subject to change without notice
The HART® communication feature on-line process calibration and
adjustment, transmitter configuration and multiple process control in
2-wire networks.
The configuration can be established from a standard HART® configurator or the dedicated FlexProgrammer configuring tool connected to
a PC.
