Important notes
Usage for the intended purpose
The temperature sensor TRG 5-6.. in conjunction with temperature switches TRS 5-50, TRS 5-52 or
with temperature transmitter TRV 5-40 are designed for measuring temperatures in steam or hot water.
Danger
The temperature sensors TRG 5-63 or TRG 5-64 are screwed into vessels or pipes. When
loosening the temperature sensor steam or hot water might escape! This presents the risk
of severe scalding all over the body!
It is therefore essential not to dismantle the temperature sensor unless the boiler pressure
is verified to be 0 bar.
The temperature sensor becomes hot during operation.
Risk of severe burns to hands and arms.
Before carrying out installation and maintenance work make sure that the equipment is cold.
Safety note
Safety temperature limiters/monitors are items of equipment with safety function (PED) and must only be
installed, wired and commissioned by qualified and competent staff.
Retrofitting and maintenance work must only be performed by qualified staff who - through adequate
training - have achieved a recognised level of competence.
The temperature sensors TRG 5-63, TRG 5-65, TRG 5-66 and TRG 5-67 feature one integrated platinum
resistance thermometer Pt 100 to EN 60751 each.
The temperature sensors TRG 5-64 and TRG 5-68 are equipped with two platinum resistance
thermometers Pt 100 for the connection of additional indicating equipment.
The ohmic resistance of the resistance thermometer changes as a function of temperature. If a
constant current is applied, the voltage produced by the change of resistance is measured and further
processed in the temperature switch or temperature transmitter.
The temperature sensor can be used as measuring transducer for
na safety temperature monitor/limiter in conjunction with temperature transmitter TRV 5-40 and
control unit NRS 1-40.1
na temperature monitor/controller in conjunction with temperature transmitter TRV 5-40 and
switching controller TRS 5-40
na safety temperature monitor/limiter in conjunction with temperature switch TRS 5-50
na temperature monitor in conjunction with temperature switch TRS 5-52
Function
Attention
The name plate specifies the technical features of the equipment. Note that any piece of
equipment without its specific name plate must neither be commissioned nor operated.

Directives and standards
Pressure Equipment Directive 2014/68/EU
Safety temperature limiters/monitors are safety accessories as defined in the Pressure Equipment
Directive (PED). The temperature switch TRS 5-50 and the temperature transmitter TRV 5-40 (together
with control unit NRS 1-40.1) in conjunction with temperature sensors TRG 5-6.. are EC type approved
according to EN 12952/EN 12953. These Directives state, among other things, the requirements made on
limiting systems and equipment for steam boiler plants and (pressurised) hot-water installations.
Functional Safety acc. to IEC 61508
The temperature switch TRS 5-50 and the temperature transmitter TRV 5-40 (together with control unit
NRS 1-40.1) in conjunction with temperature sensors TRG 5-6.. are certified to IEC 61508.
This standard
describes the functional safety of safety-related electrical/electronic/programmable electronic
systems.
The equipment combination TRG 5-6.. + TRS 5-50 corresponds to a type B subsystem with Safety
Integrity Level (SIL) 3.
The combination TRG 5-6.. + TRV 5-40 (with NRS 1-40.1) corresponds to a type B subsystem with
Safety Integrity Level (SIL) 2.
According to the European Directive 2014/34/EU the equipment must not be used in explosion-risk
areas.
ATEX (Atmosphère Explosible)
DIN EN 14597
The temperature sensor TRG 5-6.. in conjunction with temperature switches TRS 5-50 and TRS 5-52
or in conjunction with temperature transmitter TRV 5-40 (together with control unit NRS 1-40.1)
is type
approved to DIN EN 14597.
DIN EN 14597 describes and specifies the requirements made on (safety) temperature limiters/monitors.
Approvals for Marine Applications
The temperature sensor TRG 5-6.. in conjunction with
temperature switch TRS 5-50 is approved for
marine applications.
Note on the Declaration of Conformity / Declaration by the Manufacturer
