iTEMP TMT82 Dual-Input Temperature Transmitter
Part number TMT82-AAA1CA1BAAAA
Head transmitter with two RTD/thermocouple inputs, HART 7, sensor backup, drift detection and SIL2 for critical temperature points.
- CE
- SIL2
- ATEX
- IECEx
- RoHS
- EAC

Overview
The iTEMP TMT82 accepts two sensors — RTD or thermocouple, in any combination — and keeps the loop alive if one fails by switching to the backup automatically. It also compares the two sensors to detect drift and monitors thermocouple corrosion, so problems are flagged before they corrupt a measurement. HART 7 communication and SIL2 certification make it the transmitter of choice for reactor, pipeline and steam temperature points where a single sensor failure is not acceptable.
Key features
- Dual RTD/TC input with automatic sensor backup
- Sensor drift detection and thermocouple corrosion monitoring
- HART 7, configurable via FieldCare, DeviceCare or handheld
- SIL2 (IEC 61508) for safety loops
- Mounting in DIN form B sensor head or DIN rail
Typical applications
- Reactor temperature
- Pipeline skin temperature
- Redundant tank measurement
- Steam systems

Frequently asked questions
Is the TMT82-AAA1CA1BAAAA available from stock, and what is the lead time?
Availability of the iTEMP TMT82 Dual-Input Temperature Transmitter changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the TMT82-AAA1CA1BAAAA genuine, and what documentation comes with it?
We supply only genuine Endress+Hauser products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the TMT82-AAA1CA1BAAAA outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the TMT82-AAA1CA1BAAAA is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
