Temperature sensors TR 25, series Omnigrad T, are resistance 
thermometers suitable for almost all industrial processes and 
generic applications thanks to their modular structure.
They are made up of a measurement probe without a protection 
well, and a housing, which may contain the transmitter for con-
version of the variable measured.

Application areas

• Fine chemicals industry
• Light energy industry
• General industrial services
• Environmental engineering

Features and benefits

• SS 316L/1.4404 for probe "wetted" parts
• The most common compression junctions are supplied as 

standard; others are available upon request

Insert (not replaceable) in mineral oxide with a diame-
ter of 6 mm

• Customized immersion lenght
• Probe end with reduced diameter for a faster response time
• Surface finishing down to Ra < 0.8 

μ

m

• Stainless steel, aluminium or plastic housing, with protection 

grade from IP65 to IP67

• Replaceable mineral insulated insert, with diameter 6 or 3 mm
• PCP (4...20 mA, also with enhanced accuracy), HART® and 

PROFIBUS-PA® 2-wire transmitters

• Pt 100 sensing element with class A accuracy (DIN EN 60751) 

or 1/3 DIN B

• Pt 100 wire wound (-200...600°C) or thin film (-50...400°C)
• Double Pt 100, for redundancy purposes
• Single Pt 100 with 4 wires connection, double Pt 100 with 3 

wires

• EA calibration certificate
