Product Description
1. Product Overview
The TMT162-A21331BAE is a 2-channel universal HART® field temperature transmitter from Endress+Hauser iTEMP series, designed for on-site temperature conversion, signal transmission and sensor monitoring in industrial process plants. This specific model is equipped with aluminum field housing, backlit rotatable display, galvanic isolation, and full hazardous area certifications, supporting dual independent sensor inputs for RTD, thermocouple, resistance and mV signals. It converts multi-type temperature sensor signals into standard 4–20mA analog output with HART digital communication, compatible with handheld communicators, DCS and PLC systems for remote configuration and diagnostic managemen.
2. Core Technical Characteristics
Universal Dual Sensor Input
- Supports 2 independent measurement channels for Pt100/Pt1000 RTDs, all standard thermocouples (K/J/T/S/R/B/E/N), resistance (Ω) and millivolt (mV) sensors
- Dual-channel functions: average value, difference calculation, sensor redundancy comparison for critical process safety
- High measurement accuracy: ≤0.1 K for Pt100 under normal operating conditions, excellent long-term stabilit
HART Communication & Electrical Performance
- Standard HART 7 protocol, scalable 4–20mA analog output; supports multi-drop mode
- Wide power supply range: 11.5–42 V DC, reverse polarity protection, max load current ≤23 mA
- 2 kV galvanic isolation between sensor input and current output, eliminates ground loop interference
- Dual parameter write protection: hardware DIP switch lock + software password lock to avoid unauthorized modification
- Configurable fault current values compliant with NAMUR NE43 for sensor break/short alarm
Mechanical & Housing (A21331BAE Configuration)
- Die-cast aluminum dual-compartment housing, IP66/IP67 protection, dustproof and splash-proof
- Separated wiring terminal compartment and electronics compartment, prevents wiring moisture contaminating circuit boards
- Integrated rotatable backlit LCD display (90° adjustable), shows measured value, bar graph, channel status and diagnostic codes
- Multiple cable gland ports for flexible field wiring; compact potted electronic module resists vibration and humidity
- Operating ambient temperature: -40 °C ~ +85 °C
Global Hazardous & Functional Safety Certifications
- ATEX, IECEx, FM, CSA explosion-proof approvals (Ex ia / Ex d / dust ignition-proof) for Zone 0/1/2 hazardous locations
- SIL 2 certified per IEC 61508 for safety instrumented systems (SIS), meets ESD & EMC industrial standards
- Marine approval available for offshore oil & gas application
Standardized NAMUR Diagnostic Function
Full NAMUR NE107 compliant self-diagnosis, automatically identifies:
- Sensor open circuit, short circuit, out-of-range measurement
- Transmitter hardware failure, power supply abnormality
- Memory error, communication fault; diagnostic codes readable via display or HART communicator
3. Main Advantages
-
Dual-channel universal sensor compatibility reduces spare part inventory
One single transmitter supports all mainstream temperature sensors, enabling dual-point temperature monitoring, differential temperature calculation and redundant sensor verification, cutting procurement and stock costs.
-
Dual-compartment rugged housing for harsh workshop conditions
Separated wiring and electronics chambers isolate moisture, dust and corrosive gas; fully potted circuit board provides superior anti-vibration performance for chemical, power and mining sites.
-
High isolation eliminates ground loop measurement error
2 kV galvanic isolation between sensor side and output side solves signal drift caused by potential difference in multi-sensor field wiring, ensuring stable temperature readings.
-
Convenient local & remote operation
- Local: Rotatable backlit LCD for direct on-site reading without handheld tools
- Remote: Configurable via Field Xpert SFX series, 475 HART communicator or PC software; remote parameter adjustment, calibration and fault query
-
Complete safety certifications for critical process industries
Combined explosion-proof, SIL 2 and marine approvals cover refineries, petrochemicals, power plants and offshore platforms, satisfying international safety audit requirements.
-
Rich intelligent diagnostic minimizes maintenance downtime
NAMUR standard fault codes quickly locate sensor or transmitter failure, reducing inspection time for field maintenance teams; lockable parameter setting prevents on-site misoperation.
-
Wide voltage range and robust circuit protection
Works stably with unstable industrial DC power; built-in overvoltage, reverse connection and short-circuit protection extend service life in complex electrical environments.
4. Typical Application Scenarios
- Temperature monitoring of reactors, pipelines, furnaces and storage tanks in chemical & petrochemical plants
- Power plant boiler, turbine and feedwater temperature measurement
- Oil & gas onshore and offshore hazardous area temperature detection
- Food, pharmaceutical hygienic process temperature control
- Water treatment, metallurgy and mining industrial temperature loop monitoring
- Safety instrumented systems (SIS) over-temperature protection interlock
