Temperature transmitter is accurate,
reliable
Temperature transmitter offers the maximum functional safety with EMC immunity to NAMUR NE 21, signal on alarm functions to NAMUR NE 43 and basic NAMUR NE 89 requirements.
Endress+Hauser's iTemp TMT162 transmitter delivers reliable results, time after time Reliable and robust, the TMT162 field transmitter offers the maximum in functional safety with EMC immunity to NAMUR NE 21 (insensitive to motors and generators), signal on alarm functions to NAMUR NE 43 and basic requirements to NAMUR NE 89 (providing information on sensor input corrosion and excess ambient temperature)

How to save 5-20% through energy monitoring
A range of equipment for automatic data collection, energy monitoring and targeting software can save between 5% and 20% by monitoring and targeting energy consumption.
Data recorder is paperless, safe and secure
Data recorder provides safe, secure data acquisition, analysis, trending and visualisation for reliable, incorruptible data for environmental protection, pollution control and plant safety.
In addition, the TMT162 is ATEX certified (Ex ia, Ex d, Ex nA) for hazardous area use and stainless steel housing is available as an option, offering excellent protection in harsh environments.
The TMT162 features a brilliant rear-illuminated display: measured values can be easily read from a distance or in difficult conditions, day or night.
Set-up is quick and easy and can be done online, so there is no need to disconnect the measuring point when re-programming.
What's more, with its dual sensor input, the TMT162 also offers options such as sensor backup, sensor drift recognition, average and discrepancy values and automatic sensor switching.
Using the free ReadWin software, individual linearisation curves can be generated and configured into the transmitter to increase accuracy.
These linearisation curves have between two and 100 sampling points and can be entered as either a resistance figure, a difference in temperature or a milliamp figure against a given temperature.
In addition, to further increase measuring point reliability, Callender van Dussen constants can also be programmed into the transmitter to effectively remove sensor error in the temperature loop.
The TMT162 also offers safe process guidance via presettable fault conditioning.
It is possible to set three stages (0, 2, 5s) over which the actual analogue output value is 'frozen' before a fault condition is recognised and an alarm is raised.
With a presettable fault signal between 21.6 and 23mA, the TMT162 can be easily connected to any of a number of process control systems for maximum versatility.
Offering SIL2 classification and first-rate specifications, the TMT162 temperature transmitter clearly demonstrates what it was designed to do: perform critical temperature measurements in the life sciences, chemical, petrochemical, power and oil and gas industries.
HART and FOUNDATION Fieldbus compatible, it's also easily retrofitted into existing systems. Request a free brochure from Endress + Hauser ...
