Description

Applications

• Linearised temperature measurement with PT100/1000, Ni100/1000, or TC sensor.
• Difference or average temperature measurement of 2 resistance or TC sensors.
• Conversion of linear resistance variation to a standard analogue current signal, for instance from valves or Ohmic level sensors.
• Amplification of a bipolar mV signal to a standard 4-20 mA current signal.
• Connection of up to 15 transmitters to a digital 2-wire signal with HART® communication.

Features

• RTD, TC, Ohm, or mV input
• Galvanic isolation
• For DIN form B sensor head mounting
• Extremely high measurement accuracy
• HART® communication

HART Protocol

The HART protocol provides a uniquely backward compatible solution for instrument communication as both 4-20 mA analog and digital communication signals are transmitted simultaneously on the same wiring. The Loop Link Programming Kit can configure the individual transmitters for multidrop mode and provide it with a unique polling address. HART provides many benefits promised by fieldbus, while retaining the compatibility and familiarity of existing 4-20 mA systems.
