Proximity devices with analog output

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

3.1 Basic definitions
3.1.1
proximity device with analog output
PDAO
device producing an output signal which varies continuously depending on the physical quantity
(e.g. distance, speed, rotation, etc.) detected/calculated by the proximity device in relation to
its target object(s)
3.1.2
lower range value
minimum stated input value above which the output signal varies continuously
3.1.3
upper range value
maximum stated input value below which the output signal varies continuously

IEC 60947-5-7:2024 © IEC 2024 – 9 –
3.1.4
range of input values
range defined by lower range value and upper range values of the sensing element detection
capability, or calculated value (e.g. distance, speed, r/min, etc.), within which the limits of
uncertainty of the proximity device are specified
Note 1 to entry: A principle diagram describing the terms of 3.1.2 to 3.1.4 is given in Figure 3.
3.1.5
span
range of input values
algebraic difference between the values of the upper and lower limits of the measuring range
Note 1 to entry: Upper and lower limits do not reflect the sensing capabilities of the device, but the relevant upper
and lower values for the application.
Note 2 to entry: The CDD code of this entry for Electronic Data Exchange is ABB785, modified ("other variables"
removed).
[SOURCE: IEC 60050-311:2001, 311-03-13, modified — Notes to entry added]
3.2 Operation of a proximity device
3.2.1
linearity
ability of a proximity device to provide an indication having a linear relationship with a defined
quantity other than an influence quantity
Note 1 to entry: The method of expression of lack of linearity is different for different kinds of device and is
established in each particular instance.
[SOURCE: IEC 60050-311:2001, 311-06-05, modified – "measuring instrument" replaced by
"proximity device"]
3.2.2
conformity of the output signal curve
ability of a proximity device to provide an indication having a specified characteristic curve
which can be linear, logarithmic, parabolic, etc.
3.2.3
non-linearity
deviation from ideal behaviour for devices that have a linear input/output relationship,
determined from the curve plotted using the overall average of corresponding upscale and
downscale errors
Note 1 to entry: Non-linearity can be calculated and expressed in one of three ways: – independent: line positioned
so as to minimize the maximum deviation; – terminal-based: line positioned so as to coincide with the actual
characteristic curve at the upper and lower range-values; – zero-based: line positioned so as to coincide with the
actual characteristic curve at the lower range-value.
Note 2 to entry: The corresponding properties can be found in the CDD.
Note 3 to entry: Linearity is defined in IEC 60050-300:2001, 311-06-06.
Note 4 to entry: Non-linearity does not include hysteresis.
Note 5 to entry: Conformity is often used in conjunction with non-linear curves.
[SOURCE: IEC 61987-13:2016, modified — Notes to entry added]

– 10 – IEC 60947-5-7:2024 © IEC 2024
3.2.4
non-conformity of the output signal curve
deviation from ideal behaviour for devices that have a non-linear input/output relationship,
determined from the curve plotted using the overall average of corresponding upscale and
downscale errors
Note 1 to entry: The non-conformity is defined as the closeness with which an average error curve approximates to
a specified characteristic curve (which can be linear, logarithmic, parabolic, etc.).
3.2.5
true value
value consistent with the definition of a given particular quantity
Note 1 to entry: This term is used in the "true value" approach.
Note 2 to entry: Value that would be obtained by a perfect measurement.
Note 3 to entry: True values are by nature indeterminate.
Note 4 to entry: The indefinite article "a", rather than the definite article "the", is used in conjunction with "true
value" because there can be many values consistent with the definition of a given particular quantity.
[SOURCE: IEC 60050-311:2001, 311-01-04]
3.2.6
conventional true value
value attributed to a particular quantity and accepted, sometimes
by convention, as having an uncertainty appropriate for a given purpose
Note 1 to entry: This term is used in the "uncertainty" approach.
Note 2 to entry: The "conventional true value" is sometimes called "assigned value", "best estimate of the value",
"conventional value" or "reference value". The term "reference value", in this sense, should not be confused with
"reference value" in the sense used in IEC 60050-311:2001, 311-07-01.
Note 3 to entry: Frequently, a large number of results of measurement of a quantity are used to establish a
conventional true value.
Note 4 to entry: An alternative concept of measurement uncertainty used for measurement instruments is described
in IEC Guide 115:2021, Application of uncertainty of measurement to conformity assessment activities in the
electrotechnical sector.
3.2.7
inaccuracy
maximum positive and negative deviation from the specified characteristic curve observed in
testing a device under specified conditions and by a specified procedure
Note 1 to entry: Accuracy is defined in IEC 60050-311:2001, 311-06-08.
[SOURCE: IEC 61298-1:2008, 3.5]
3.2.8
long term drift
drift in output monitored for 30 days at 90 % of span
[SOURCE: IEC 61987-1:2008, 3.22]

IEC 60947-5-7:2024 © IEC 2024 – 11 –
3.2.9
long term stability
drift of zero output signal in percent of full scale limit after a given period of normal operating
conditions
Note 1 to entry: The long term stability can be evaluated over a different period of time, e.g. 6 months, 1, 2 or 5
years. Sometimes manufacturers declare a life-time stability.
Note 2 to entry: Depending the type of a proximity device, the drift can be referred to an upper range limit, a fixed
value, a full scale, etc.
3.2.10
repeatability
value of variation of the output signal under specified conditions expressed as a percentage of
the span
Note 1 to entry: This definition is more general and not equal to the definition in IEC 60947-5-2:2019.
3.2.11
resolution value
resolution of the value of the physical quantity
Note 1 to entry: The resolution value from the digital output value and the analog output value can be different.
3.2.12
error
discrepancy between a computed, observed or measured value or condition, and the true,
specified or theoretically correct value or condition
Note 1 to entry: An error within a system may be caused by failure of one or more of its components, or by activation
of a systematic fault.
[SOURCE: IEC 60050-192:2015, 192-03-02]
3.2.13
linearity error of the digital output
