1. Safety
Intended use
The sensor measures temperatures of liquids and
solids within the range of –50 … 400 °C.
The sensor must only be used for media against
which the housing material and sensor tip are
resistant.
Staff qualication
Only use staff who are trained for the activities
described. This applies in particular to assembly,
installation, conguration and troubleshooting.
Make sure that the staff have read and understood
these instructions.
Electrical connection and EMC
All electrical wirings must comply with local
standards and connections must be made
according to the connection diagrams.
Technical condition
Only use sensor in perfect technical condition.
Only use Baumer accessories.
Baumer will accept no liability for other
manufacturers’ accessories.
Operation
The power supply and environmental conditions
must comply with the specications of the device.
Before switching the device on and off, possible
effects on other equipment and the process run
must be checked.
Risk of burns from hot media
During operation the sensor housing may warm
up to over 50 ºC. When working with hot media
provide protection against burns.

1 DFON display
2 Process connection
3 Sensor tip
The TFRH/N is a high-end programmable
temperature sensor based on RTD technology.
The output signal is a Pt100 signal that can be
transformed to a 4 … 20 mA output signal if a
temperature transmitter is built-in. Depending on
the type of sensor, temperature measurements
from –50 … 400 °C are possible.
Programming can be done via the touch screen
display or via the FlexProgram.

7. Electrical connection in explosion hazardous areas
DANGER
Risk of fatal accident due to a wrongly connected sensor
Correct gas and dust protection can only be achieved by meeting their installation requirements.
fMake sure that all requirements are met and that sensor and installation have a valid approval
for their specic explosive atmosphere.
fAllow only persons trained in explosion protection to perform the installation.
fNever use FlexProgrammer in explosion hazardous areas.
7.1 Explosive gas atmospheres zone 0, 1 and 2
The TFRH/N can be used with built in FlexTop™ 22xx transmitter in explosion hazardous areas of
zone 0, 1 or 2. Sensors must be installed with Zener barriers. If electrostatic dissipative film on display
cover becomes damaged, discontinue use in zone 0.
Approval for TFRH/N-xxxx.x1xx.xxxx.xxxx.xxxx: ATEX II 1G/IECEx Ex ia IIC T6...T4
All TFRH/N with intrinsic safety protection ia
fUse Zener barriers.
fIf enabled, protect each relay by a separate Zener barrier or use a barrier with multiple channels.
fDepending on the transmitter type, comply with the following temperatures and connection values.

1. Sicherheit
Bestimmungsgemässe Verwendung
Der Sensor dient zum Messen der Temperatur
von Flüssigkeiten und Feststoffen im Bereich
–50 … 400 °C.
Der Sensor darf nur für Medien eingesetzt
werden, gegen die das Gehäusematerial und die
Sensorspitze resistent sind.
Personalqualikation
Setzen Sie nur Mitarbeiter ein, die zur
Durchführung solcher Arbeiten ausgebildet
wurden. Dies gilt insbesondere für Montage,
Installation, Konguration und Störungsbehebung.
Sicherstellen, dass das Personal diese Anleitung
gelesen und verstanden hat.
Elektrischer Anschluss und EMV
Sämtliche elektrische Leitungen müssen die
örtlichen Auagen erfüllen und Verbindungen
sind anhand des Verkabelungsdiagramms
durchzuführen.
Technischer Zustand
Den Sensor nur dann benutzen, wenn er sich
in einem einwandfreien technischen Zustand
bendet.
Nur Zubehör von Baumer verwenden.
Für Zubehör anderer Hersteller übernimmt Baumer
keine Haftung.
Betrieb
Die Stromversorgung und die
Umgebungsbedingungen müssen die
Gerätespezizierungen erfüllen.
Bevor Sie das Gerät ein- und ausschalten, prüfen
ob eventuelle Auswirkungen auf andere Geräte
und das Prozessverfahren vorhanden sind.
Verbrennungsgefahr bei heissen Medien
Das Gehäuse des Sensors kann sich im Betrieb
auf über 50 °C erwärmen. Bei heissen Medien für
Verbrennungsschutz sorgen.

Der TFRH/N ist ein programmierbarer High-End-
Temperatursensor basierend auf RTD-Technologie.
Das Ausgangssignal ist ein Pt100-Signal, das
bei integriertem Temperaturmessumformer in ein
Ausgangssignal mit 4 … 20 mA umgewandelt
werden kann. Je nach Sensortyp sind
Temperaturmessungen im Bereich –50 … 400 °C
möglich.
Die Programmierung kann über den Touchscreen
oder über das FlexProgram erfolgen.
