Features of the 520 transmitters

Basic accuracy and long-term stability

The combination of a high-efcient 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.

Ambient temperature stability

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 inuence to a minimum.

Customized linearization

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.

Adjustable ltering

For smoothing down instabilities on the input, an additional lter, with an adjustable ltering level can be activated.

Sensor matching doubles the accuracy

This function compensates for deviations (compared to actual standard values) in connected sensors. A reduction of the total meas­urement error, for the sensor/transmitter combination, of more than 50 % is typical.

Sensor backup

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.

Single-sensor or dual-sensor input

The dual-sensor input for RTD, Resistance or Thermocouple allows for 3 output alternatives, each represented by a 4-20 mA signal:

1. The measured value of sensor 1

2. The measured value of sensor 2

3. A calculated value from sensor 1 and 2, e.g. Difference, Average, Minimum and Maximum.

Sensor drift monitoring

If an RTD or thermocouple with double sensor elements is used, the 520 transmitters can detect sensor drift by checking the read-

ing from both elements. If the difference is above a user-dened level, this will be indicated in ConSoft and with a diagnostic HART

message, and the output signal can be forced upscale or downscale.

Sensor isolation monitoring

The isolation resistance of thermocouples and RTD’s as well as the cabling between sensor and transmitter is being monitored. If

the isolation is below a user-dened level, this will be indicated in ConSoft and with a diagnostic HART message, and the output

signal can be forced upscale or downscale. This feature requires an extra lead inside the thermocouple or RTD.

Measurements with RTD’s and potentiometers

The 520 transmitters accept inputs from standardized Platinum RTDs acc. to IEC 60751 and JIS C 1604, Nickel RTD’s acc. to DIN
43760 and Cu10 acc. to Edison Cu Windings No. 15.

Input for plain resistance, such as potentiometers, up to 4000 Ω is available.
2-, 3- or 4-wire connection can be chosen for single-input and 2- or 3-wire connection for dual-input (See Input connections below) .

Measurements with Thermocouples and plain voltage

The 520 transmitters accept inputs from 10 types of standardized thermo¬couples as well as plain mV input up to 1000 mV.
For T/C input, the CJC (Cold Junction Compensation) is either fully automatic, by means of an internal accurate sensor, external
with Pt100 sensor or xed by entering an external CJ temperature.

SIL 2 compliance

Based on a hardware assessment according to IEC 61508-2, consisting of a FMEDA done by Exida, C520S and C520XS are suitable

for use in SIL 2 rated Safety Instrumented Systems (SIS). See the Safety Manual for details.

ConSoft conguration software

The PC conguration software, ConSoft, is a versatile and user-friendly tool for transmitter conguration, loop check-up and sensor
diagnostics. It runs on Windows NT, 2000, XP, Vista, Windows 7 and Windows 8. All features described in this data sheet are handled

in a simple and fail-safe way.

ConSoft is part of the complete Conguration Kit ICON, which also contains a USB Interface and necessary cables.

Conguration alternatives

In addition to ConSoft (see above) the following conguration alternatives are available:
Hand held communicator, e.g. FC375 (Emerson)

Management systems, e.g. AMS (Emerson) and PDM (Siemens)

EDD enabled systems – “520 EDD” available on our website.
DTM/FDT enabled systems – “520 DTM” available on our website.

HART 6 compliance

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.
