Application
The iTEMP® TMT162 temperature field transmitter is a two-wire device
with optional FOUNDATION FieldbusTM , PROFIBUS® PA or HART® protocol, two
sensor inputs for resistance thermometers (RTD) and resistance
transmitters (O), thermocouples (TC) and voltage transmitters (mV). The
illuminated display shows the current measured value or values of remote
devices digitally and as bar graph with an indicator for alarms.
Features and benefits:
* Highest reliability in harsh industrial environments due to dual
compartment housing and compact fully potted electronics
* Backlit display with large measured value, bargraph and fault
condition indication for ease of reading
* Dual sensor input capability e.g. 2 Pt100 3-wire or 1 Pt100 4-wire &
TC
* Non volatile peak indicator for min/max values
* Sensor monitoring: Breakdown information, sensor backup, sensor drift
alarm, threshold switch-function and corrosion detection avoids shut
down and enables a quick maintenance intervention
* Sensor matching: Linearization with Callendar van Dusen or
polynomial-equation allowing optimal accuracy of the temperature
measurement
* Mathematic functions for differential average temperature add
flexibility to the measurement
* Operation, visualization and maintenance with PC, e.g. using
Fieldcare, AMS, DeltaV, National Configurator, PDM, Yokogawa (VP,
CS3000, Stardom), ABB (AC800, Freelance), Honeywell (PKS Expirion,
Plantscape), Foxboro (Invensys)
* High accuracy in entire operating range < (0.1°C) (0.18°F)
* FISCO/FNICO-compliant in accordance with IEC 60079-27 for
straightforward design of measuring points in hazardous areas
* Approvals: FM and CSA (IS, NI, XP and DIP), ATEX (EEx ia, EEx nA, EEx
d and dust-Ex)
* Galvanic isolation 2 kV (from the sensor input to the output and the
housing)
* Transducer blocks provide wizards (methods) for easy and safe
configuration
* Output simulation for a quick and easy check of the loop
* Optional: stainless steel housings for hygienic or EEx d applications
