INOR IPAQ C520 Temperature Transmitters

The INOR IPAQ C520 temperature transmitters are universal, isolated, dual-input temperature transmitters with additional voltage and resistance input. The 520 transmitters are universal, isolated, dual-input temperature transmitters with additional voltage and resistance input. Typical characteristics are the high accuracy, reliable measurements, product safety and user efficiency. The transmitters are compatible with the HART 6 protocol offering extended diagnostic information.

The combination of a high-efficient 50-point linearization and an electronic design based on the most precise and "zero-drift" technology results in a high basic accuracy and excellent long-term stability. The drift over 5 years is guaranteed to maximum of ±0.05 °C or ±0.05 % of the measuring span. Features like continuous self-calibration of the input AD converter in every measurement cycle and a "zero-drift" current generation of the output DA converter have strongly reduced the ambient temperature influence to a minimum.

For resistance and mV inputs, the 50-point Customized Linearization can provide a correct process value, in a choice of engineering units, for a sensor with non-linear input/output relation. For smoothing down instabilities on the input, an additional filter, with an adjustable filtering level can be activated. Dual-sensor input allows for backup between two sensors. Should a lead break or short-circuit be detected on one of the sensor circuits, an automatic switchover to the intact sensor will occur.

The 520 transmitters are fully compliant with the HART 6 protocol as well as the previous HART 5. HART 6 offers the possibility to receive diagnostic information such as sensor errors or sensor conditions, input wiring resistance too high, sensor backup mode, transmitter error etc. See User Instructions for details.
