maintenance using universal device configuration tools like FieldCare, DeviceCare or
FieldCommunicator 375/475. For more information, see the Technical Information.
PROFIBUS ® PA head transmitters
Universally programmable head transmitter with PROFIBUS ® PA communication. Conversion of
various input signals into digital output signals. High accuracy over the complete ambient
temperature range. The configuration of PROFIBUS PA functions and of device-specific parameters is
performed via fieldbus communication. For more information, see the Technical Information.
FOUNDATION Fieldbus™ head transmitters
Universally programmable head transmitter with FOUNDATION Fieldbus™ communication.
Conversion of various input signals into digital output signals. High accuracy over the complete
ambient temperature range. All transmitters are released for use in all important process control
systems. The integration tests are performed in Hauser's "System World". For more
information, see the Technical Information.
Advantages of the iTEMP transmitters:
• Dual or single sensor input (optionally for certain transmitters)
• Pluggable display (optionally for certain transmitters)
• Unsurpassed reliability, accuracy and long-term stability in critical processes
• Mathematical functions
• Monitoring of the thermometer drift, sensor backup functionality, sensor diagnostic functions
• Sensor-transmitter matching for dual sensor input transmitters, based on Callendar/Van Dusen
coefficients
Field transmitter
Field transmitter with HART® or FOUNDATION Fieldbus™ communication and backlit display. Can
be read easily from a distance, in sunlight and at night. Large measurement value, bargraph and
fault indication displayed. Benefits are: dual sensor input, highest reliability in harsh industrial
environments, mathematic functions, thermometer drift monitoring and sensor back-up
functionality, corrosion detection.

In applications where fast response time is needed, grounded thermocouples are recommended.
This thermocouple design may cause a ground loop. This can be avoided by using iTEMP
transmitters with high galvanic isolation.
