Application
The iTEMP® TMT85 is a head transmitter for assembly in a terminal head
DIN form B with 2 sensor inputs for resistance thermometers in 2-wire,
3-wire or 4-wire connection, thermocouples, voltage and resistance
transmitters.
Features and benefits:
Dual sensor input capability e.g. 2 Pt100 3-wire or 1 Pt100 4-wire &
TC
Fast wiring without tools due to optional spring clips
Meets all of the requirements mentioned in NAMUR NE21 and the
recommendations in NAMUR NE89 for Temperature Transmitter with Digital
Signal Processing.
FISCO/FNICO-compliant in accordance with IEC 60079-27 for
straightforward design of measuring points in hazardous areas
International approvals for safety operation in hazardous areas like
FM and CSA (IS, NI)and ATEX EEx ia, EEx nA.For intrinsically safe
installation in zone 1 and as associated apparatus in zone 2.
High accuracy in entire operating range < (0.1°C) (0.18°F)
Galvanic isolation 2 kV (from the sensor input to the output and the
housing)
Significant improvement in the temperature measurement accuracy due
to a sensor-transmitter-matching process
Sensor monitoring: Breakdown information, sensor backup, sensor
drift alarm, threshold switch-function and corrosion detection avoids
shut down and enables a quick maintenance intervention
Mathematic functions for differential / average temperature add
flexibility to the measurement
Transducer blocks provide wizards (methods) for easy and safe
configuration
Non volatile peak indicator for min/max values
Optional: plug on display for process and device information
