All Field Analog temperature transducers are 2-wire transmitters. You do not need a separate power supply, as the products are supplied with power directly via the 4 mA ... 20 mA measuring line. This reduces wiring effort.
Field devices and loop-powered temperature transducers
Loop-powered Field Analog temperature transducers record and convert the signals from temperature sensors such as resistance thermometers, thermocouples, resistance-type sensors, and voltage sensors into a standard signal directly in the field. Via HART communication, you can transfer process data digitally and configure the transmitter remotely. Our temperature transducers are available for DIN rails or as head-mounted transducers.More information

Your advantages in detail
Conveniently configure the temperature transducers and head-mounted transmitters of the Field Analog product family via HART® communication. In addition, you have the option of receiving extended process data and extensive diagnostic functions from the device via HART®.
Depending on the device type, some field analog temperature transmitters have a dual sensor input. This allows mathematical functions to be mapped, such as a difference measurement. It is also possible to monitor a process with two different temperature sensors and to switch over from a defined temperature range.
Easy detection of temperature deviations
With the FA MCR(-EX)-HT-TS-I-OLP and MACX MCR(-EX)-TS-I-OLP(-SP)(-C) temperature transmitters, you can easily detect temperature deviations in a process. To do this, you can use the dual sensor input of the devices and connect two sensors: For example, you can use two 2-conductor Pt100 sensors or one 4-conductor Pt100 sensor and one TC sensor. Configuring the temperature transmitter for recording the temperature difference is convenient and simple via the FDT container and corresponding DTM. If the temperature at the measuring point deviates, a HART® signal is generated which signals the deviation to the controller.
Please note that two temperature transmitters must be used for SIL 3 applications.
