TMT162

Application The iTemp temperature field transmitter TMT162 is a two-wire transmitter with HART or Fieldbus output, two measuring inputs for resistance thermometers in 2-wire, 3-wire or 4-wire connection, thermocouples, resistance and voltage. 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 * 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 enableds a quick maintenance intervention * Sensor matching: Linearization with Callendar van Dusen or polynomial-equation allowing for 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, Delta V, National Configurator, PDM, Yokogawa (CS3000, Stardom), ABB (AC800, Freelance), Honeywell (PKS Expirion, Plantscape), Foxboro (Invensys) * High accuracy in entire operating range < (0.1°C) (0.18°F) * FISCO/FINCO compliant according to IEC 60079-27 * Approvals: FM anc 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) * Output simulation for a quick and easy check of the loop * Optional: stainless steel housings for hygienic or EEx d applications
