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
