Loop-powered temperature transducers for RTDs, TCs, resistance-type sensors, and voltage sensors

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.

Your advantages

  • Acquire temperatures directly in the field without a separate power supply with loop-powered supply from the measuring circuit
  • Transmit and display process data digitally and configure it remotely via integrated HART® communication
  • Suitable for global use with international approvals
  • Also for intrinsically safe circuits in the Ex area: Versions with ATEX/IECEx, CSA, and FM approval

Your advantages in detail

Temperature transducers for the DIN rail and temperature head-mounted transducer with supply from the measuring circuit
Temperature transducers for DIN rails and temperature head-mounted transducers
Temperature transducers for DIN rails and temperature head-mounted transducers with dual sensor input
Temperature transducers for the DIN rail and temperature head-mounted transducer with supply from the measuring circuit

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.

Temperature transducers for DIN rails and temperature head-mounted transducers

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®.

Temperature transducers for DIN rails and temperature head-mounted transducers with dual sensor input

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

Detection of temperature deviations via dual sensor input

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.
