Technical Information
omnigrad M TR 44, TR 45
Hygienic RTD temperature sensor assembly
With or without thermowell and M.I. replaceable insert
PCP (4...20 mA), HART
The Omnigrad M type TR 44 and TR 45 temperature sensors are
resistance thermometers especially designed for hygienic appli-
cations (food, pharmaceutical and fine chemicals industry).
They consists of a measurement probe with (TR 45) or without
(TR 44) a protection well, and a housing, which may contain the
transmitter for the conversion of the measured variable.
Due to their modular design, TR 44 and TR 45 fit to all sanitary
industrial processes

Features and benefits
®
• 3-A
and EHEDG certification
• SS 316L/1.4435 for "wetted" parts (BN 2 compliance on
request)
• Most common hygienic process connections supplied as
standard; other on request
TI244T/02/en
N° 60018846
®
or PROFIBUS-PA
• Customized immersion length
• Small probe diameter or reduced tip for fast response time (TR
44)
• Tapered or reduced tip and thermoconductive paste for fast
response time (TR45)
• Surface finishing down to Ra < 0.4 mm, with or without elec-
tropolishing
• Stainless steel, aluminum or plastic housing, all of which are eas-
ily cleanable and IP65 to IP67
• Replaceable mineral insulated insert (TR 45), which is installed
inside the thermowell, avoids plant shut down during the substi-
tution or the verification of the instrument
• PCP (4...20 mA, also with enhanced accuracy), HART
PROFIBUS-PA
• Pt100 sensing element with class A accuracy (DIN EN 60751) or
1/3 DIN B
• Double Pt100, for redundancy purposes
• Pt100 with 4 wires connection, double Pt100 with 3 wires
• ATEX 1 or 1/2 GD EEx ia certification (TR 45)
• Material certification (3.1.B, ...)
• EA calibration certificate
• Ferrite content determination
• Sensor matching calibration

    Equipment architecture The Omnigrad M TR 44 and TR 45 temperature sensors are made up of a measurement probe, with (TR 45) or without (TR 44) a protection well, and a housing (head), which may contain a transmitter or the terminals for the electrical connection.
  • Page 3 The "4 wires" configuration ensures no additional errors in case of long connecting cables (without head- mounted transmitter). Generally speaking, there is a higher guarantee of accuracy in the "4 wires" configuration. Measurement range • TR 44 -50…250°C • TR 45 -50…400°C Endress+Hauser...

    M TR 44, TR 45 System components Housing The housing which contains the electric terminals or the transmitter, can be of different types and materials (plastic, painted aluminium, stainless steel). The way in which it fits to the rest of the probe and the gland for the cable entry ensures an IP grade of 65 at minimum (also refer to the figure below).
