General notes

G

Measuring principle of HVAC temperature sensors in general:

The measuring principle of temperature sensors is based on an internal sensor that outputs a temperature-dependent resistance signal.
The type of the internal sensor determines the output signal. The following active ⁄ passive temperat ure sensors are distinguished:

a) Pt 100 measuring resistor (according to DIN EN 60 751)
b) P t 1000 measuring resistor (according to DIN EN 60751)
c) Ni 1000 measuring resis tor (according to DIN EN 43 760, TCR = 6180 ppm ⁄ K)
d) Ni 1000_TK 5000 measuring r esist or (TCR = 5000 ppm ⁄ K)
e) L M235Z, semiconduc tor IC (10 m
f) NTC (according to DIN 44070)
g) PTC
h) K TY silicon temperature sensors

The most impor tant resist ance characteristics are shown on the last page of these operating instructions. According to their characteristics,
individual temperature sensors ex hibit different slopes in t he range bet ween 0 °C and +100 °C (TK value). Maximum-possible measuring ranges
also vary from sensor to sensor (for some examples to this see under technical data).

Design of HVAC temperature sensors in general:

Sensors are distinguished by shape type as follows: surface-contacting sensors, cable temperature sensors, and enclosure-type and built-in
temperature sensors.
– O n surface -cont acting sensors, t he tempera ture sens or has at leas t one contact area t hat must be b rought in co ntact, e .g. with th e surface o f

radia tors or pi pes. If the co ntact ar ea is not pos itioned c orrect ly relat ive to the s urface t o be measure d, signifi cant temp eratur e measurem ent
erro rs may occ ur. Good cont act area a nd temper ature co nductio n must be ens ured, dir t and uneve nness mus t be avoided , and heat -conduc tive
past e is to be used where necessary.

– On cable temperature sensors, the temperature sensor is inst alled inside a sensor sleeve, from which a connecting cable is leading out. In

addition to the standard insulating materials PVC, silicone, and fibreglass with stainless s teel texture, other versions are also available that
may allow a wider range of application.

– On enclosure-type sensors, the temperature sensor is embedded in a respective enclosure. Different designs of enclosures are available, e.g.

with an external sensor sleeve (see outside temperature sensor ATF2). Enclosure-type sensors are normally dis tinguished int o in-wall (FSTF)
and on-wall (RTF, ATF) types and indoor and wet room versions. Connection terminals are placed on a plate inside the connecting enclosure.

– Duct and built-in temperature sensors are distinguished into temperature sensors with interchangeable measuring insert and without inter

changeable measuring insert. Connection par ts are placed inside a connecting head. Standard proc ess connec tion for imm ersion sensors is a
pipe thread (sizes in inches) and a mounting flange for duct sensors. However, it may be designed differently. W hen a built- in sensor has a neck
tube, t he application range is usually some what wider since asc ending heat c annot flow d irectly and immediately i nto the connectin g head. This
is to be noted especially when transmit ters are inst alled. The temperature sensor in built- in sensors is always placed inside the front part of
the protective tube. On temperature sensors wit h short reaction times, protective tubes are stepped.

Note!

Selec t immersion dept h for buil t-in sensors so that the error caused by heat dissipation s tays w ithin t he admissible err or margins. A standard
value is: 10 x diameter of prot ection tube + sensor length. In connection with enclosure-type sensors, par ticularly with ou tdoor sensors, please
consider the influence of thermal radiation. For that purpose, a sunshade and radiation prot ector SS-02 can be attached.

Mounting and Installation

G

Devices are to be connec ted under dead- voltage condi tion. Devices
must only be connected to safety extra-low volt age. Consequential
damages caused by a fault in this device are excluded from war
rant y or liability. Installation of these devices must only be realized
by authorized qualified personnel. The technical data and connect
ing conditions shown on t he device labels and in the mounting
and operating instructions delivered together with the device are
exclusively valid. Deviations from the catalogue representation are
not explicit ly ment ioned and are possible in terms of technical pro
gress and cont inuous improvement of our products. In case of any
modif ications made by the user, all warranty claims are forfei ted.
Operating this device close to other devices that do not comply
with EMC directives may influence functionality. This device must
not be used for monitoring applications, which serve the purpose o f
prot ecting persons against hazards or injur y, or as an EMERGENCY
STOP switch for systems or machinery, or for any o ther similar
safety-relevant purposes.

Dimensions of enclosures or enclosure accessories may show slight
tolerances on the speci fications provided in these instruc tions.

Modif ications of these records are not permi tted.
In case o f a complaint, only complete devices ret urned in original

packing will be accepted.

Notes regarding mechanical mounting and attachment:

Mounting shall take place while observing all relevant regulations

-

and standards applicable for the place of measurement (e.g. such
as welding instructions, etc.). Particularly the following shall be

-

regarded:
– VDE ⁄ VDI direct ive technical t emperature measur ements,

measurement set - up for temperature measurements.

– The EMC direct ives must be adhered to.

­– It is imperative to avoid parallel laying of curr ent- carrying lines.

– We recommend to use shielded cables w ith

the shielding being att ached at one side to t he DDC ⁄ PLC.

Before mounting, make sure that the existing thermometer‘s techni
cal par ameters compl y with t he actual conditions at the place of
utilization, in particular in respect of:

– Measuring range
– Permissible maximum pressur e, flow velocit y
– Installation length, tube dimensions
– Oscillations, vibrations, shocks are to be avoided (< 0.5 g)

Attention! In any case, please observe the mechanical and thermal
load limits of protec tive tubes according to DIN 43763 respectively
according to specific S+S standards!

Resistance characteristics of passive temperature sensors (see last page)

G

In order to avoid damages ⁄ errors, preferably shielded cables are to be used.
Laying measuring cables parallel with current-carrying cables must in any case be avoided. EMC directives shall be obser ved!
These instruments must be installed by authorised specialists only!

Limiting deviation according to classes:

Tolerances at 0 °C:
