The HART® protocol makes it possible for configuration and diagnostic purposes to transmit measured and device data between the HART

masters such as the handheld module or PC-based operating programmes require so-called

HART device description files (DD = device descriptions, DTM), these make it possible to access all

information in a HART

device. Transmission of such information is done exclusively using

"commands".

There are three command classifications:

• Universal commands Universal commands are supported and used by all HART the following functionalities:

–Recognising HART

– Read out of digital measured values

• Common practice commands: These general commands offer functions that are supported or used by some but not all field devices.

• Device specific commands These commands enable access to device specific functions that are not HART Such commands access, amongst other things, individual field device information.

commands.

If several errors are present, the error with the highest priority is output. Once this error is eliminated, the next error is output! An offset of 1000 indicates that more than one error is present.

Device behavior in event of sensor error

In the event of a warning or error, the "Caution" symbol appears on the display and the error code is shown. If an error occurs, the bargraph also flashes on the display and only the error code is displayed and not the measured value. (See also Section 5.2).

8.2.1 Corrosion detection

Corrosion detection only for RTD 4-wire connection.

Sensor connection cable corrosion can lead to false measured value readings. Therefore our unit offers the possibility to recognize any corrosion before the measured values are affected.

There are 2 different steps selectable dependent on the application requirements:

• off (warning output just before reaching the alarm set point. This allows for preventative maintenance/trouble-shooting to be done.)

• on (no warning, immediate alarm)

The following table describes how the device behaves when the resistance changes in a sensor connection line, depending on whether on or off is selected.

RTD

off --- WARNING ALARM

on --- ALARM ALARM

1) Pt100 = 100 Ω at 0°C / Pt1000 = 1000 Ω at 0°C

TC < ≈ 10 kΩ 10 kΩ ≈ < x< ≈ 15 kΩ > ≈ 15 kΩ

off --- WARNING

on --- ALARM ALARM

1) If the ambient temperature is very high, it is possible to have a measured error 3 times that of the specified value.

< ≈ 2 kΩ 2 kΩ ≈ < x< ≈ 3 kΩ > ≈ 3 kΩ

ALARM

The sensor resistance can have an effect on the resistance data in the table. If all the sensor connection line resistances are increased simultaneously, the values described in the table are halved. In corrosion detection, it is assumed this is a slow process with a continuous increase in resistance.

Pyromation, Inc. 29

Trouble-shooting Series 642

8.2.2 Monitoring the supply voltage

If the necessary supply voltage is undershot, the analog output value drops approx. 3 s ≤ 3.6 mA. Error code 19 appears on the display. Then the device attempts to output the normal analog output value again. If the supply voltage remains too low, the analog output value drops again to ≤ 3.6 mA. This prevents the device from constantly outputting an incorrect analog output value.

10.1 The Callendar - van Dusen Method

It is a method to match sensor and transmitter to improve the accuracy of the measurement system. According to IEC 60751, the non-linearity of the platinum thermometer can be expressed as (1):

in which C is only applicable when T < 0 °C.

The coefficients A, B, and C for a standard sensor are stated in IEC 60751. If a standard sensor is not available or if a greater accuracy is required than can be obtained from the coefficients in the standard, the coefficients can be measured individually for each sensor. This can be done e.g. by determining the resistance value at a number of known temperatures and then determining the coefficients A, B, and C by regression analysis.

However, an alternative method for determination of these coefficients exists. This method is based on the measuring of 4 known temperatures:

•Measure R

Calculation of α

First the linear parameter α is determined as the normalized slope between 0 and 100 °C (2):

If this rough approximation is enough, the resistance at other temperatures can be calculated as (3):

and the temperature as a function of the resistance value as (4):

Calculation of δ

Callendar has established a better approximation by introducing a term of the second order, δ , into the function. The calculation of δ is based on the disparity between the actual temperature, T the temperature calculated in (4) (5):

at T0 = 0 °C (the freezing point of water)

at T

100

at Th = a high temperature (e.g. the freezing point of zink, 419.53 °C)

at Tl = a low temperature (e.g. the boiling point of oxygen, -182.96 °C)

= 100 °C (the boiling point of water)

, and

With the introduction of δ into the equation, the resistance value for positive temperatures can be calculated with great accuracy (6):

Calculation of β

At negative temperatures (6) will still give a small deviation. Van Dusen therefore introduced a term of the fourth order, β , which is only applicable for T < 0 °C. The calculation of β is based on the disparity between the actual temperature, t only α and δ (7):

With the introduction of both Callendar's and van Dusen's constant, the resistance value can be calculated correctly for the entire temperature range, as long as one remembers to set β = 0 for T > 0 °C (8):

Conversion to A, B and C

Equation (8) is the necessary tool for accurate temperature determination. However, seeing that the IEC 751 coefficients A, B and C are more widely used, it would be natural to convert to these coefficients. Equation (1) can be expanded to (9):

, and the temperature that would result from employing

and by simple coefficient comparison with equation (8) the following can be determined (10):

(11)

(12)

The device accepts the coefficients to be specified as α, β, δ and A, B, C. Information on the coefficients can be requested from the sensor manufacturers in question.

10.2 Polynomial RTD

With "Polynomial RTD", the sensor is defined by a polynomial (X4*x4+X3*x3+X2*x2+X1*x1+X0) with 5 coefficients. The physical measuring range is 10 to 400 Ω. The 5 coefficients of the polynomial are calculated using the PC configuration software TransComm Light. There are two different ways of determining the polynomial:

• The sensor-matching-calibration The deviation (compared to standard RTD) of the sensor or at the complete measuring point (transmitter with connected sensor, Measured = ΔT /°C or mA) is measured at different temperatures (sampling points). By using a "weight factor" it is possible to set special focus either on the given points (the deviation on the rest of the curve can be quite high) or on the trend compared to the reference linearization (The sampling points are only reference points of an e.g. aged sensor). These sampling points lead to a new revised linearization, which is transferred to the temperature transmitters.

• The customer specific linearization The linearization is made by measured resistance or current values over the target temperature range. These sampling points lead also to a new revised linearization, which is transferred to the temperature transmitters.

10.2.1 How to use with the PC configuration software TransComm

Light:

1. Select POLYNOM RTD in Choice-field "Sensor type".

2. Press button LINEARIZATION to open module SMC32.

3. Default setting is Sensor-matching-calibration which can be recognized by "ΔT/°C" in the

groupbox "Measured". Alternative choice is "Ohm" or "mA" for customer specific linearization.

4. Default reference RTD linearization is Pt100. Check "Type of Sensor" if another RTD is

required. With customer specific linearization it is not possible to select "Type of Sensor".

5. "Weighting" default is 50%. As described above 100% means full focus on the accuracy at the

sampling points, 0% uses the sampling points as trend information for the complete curve.

6. The "sampling points" can be edited in the shown table, default points are the min and max

temperature of the reference element. These values can be modified to a reduced range.

7. To see the results of the new linearization use menu Calculate … Calculate Curve and/or

Calculate … Show Coefficients (Coefficients are shown in an extra form).

8. The red curve in the graph (scale on right) shows the deviation between calculated and

reference curve. This graph easily shows the effect of changing the "weighting".

9. When files exist, data can also be loaded (Data … Load). Files made with older versions (SW

< 2.0) do only supply sampling points, the extra information ("Measured", "Type of Sensor") has to be edited after loading data.

10. Storing all data in files use Data … Save or Data … Save as....

11. For using this functionality in the transmitter please press OK (data will be taken over in the

PC configuration software TransComm Light) and start to transmit to the device.
