Supported Applications
The Omega TXUN-HT is a 2-wire programmable transmitter designed for linearized temperature measurement with RTD and TC sensors (e.g., Pt100, Ni100), as well as converting linear resistance or bipolar mV signals to a standard 4 to 20 mA analogue current output. The series supports the following documented applications:
- Linearized temperature measurement with TC and RTD sensors (e.g., Pt100, Ni100)
- HART® communication for individual, difference, or average temperature measurement of up to two RTD or TC sensors
- Resistance conversion from linear resistance inputs (e.g., valves or Ohmic level sensors) to 4 to 20 mA signal
- mV signal amplification converting bipolar mV signals to 4 to 20 mA current signals
- Multidrop communication supporting up to 63 transmitters in a HART® 7 setup
Operating Conditions & Performance
The TXUN-HT operates within an ambient temperature range of -40°C to +85°C and shares the same storage temperature limits. The device is designed for SIL applications with continuous checks of vital stored data. It meets EMC compliance recommendations NAMUR NE21, NE43, and NE89.
Electrical operation requires a 2-wire loop-powered installation (typically 12-36 VDC). The transmitter outputs a 4 to 20 mA analogue current signal with selectable HART® communication protocol versions: HART® 5 or HART® 7. Specific accuracy values, repeatability, hysteresis, resolution, and response time are not specified in the provided documentation.
Configuration Options
The series is configurable for various input types including RTD (e.g., Pt100, Ni100), TC (e.g., Type K, J, T, etc.), Ohm linear resistance inputs, and bipolar millivolt inputs. The model number guide follows the pattern: TXUN-HT - <Input Type> - <Configuration> - <Options>. Key capabilities include:
- Mounting / Installation: DIN form B sensor head or DIN rail mounting
- HART® 7 Features: Long Tag numbers (up to 32 characters), Enhanced Burst Mode, Event notification with time stamping, Device variable and status mapping, Process signal trend measurement, Automatic event notification, Command aggregation
- Safety & Approvals: UL Listed, cULus, CE, EAC, FM Approved, Ex (Intrinsically Safe), INMETRO, NCC; suitable for use in hazardous gas and dust areas
- Configuration Options: Standard HART® communication interfaces or TXUN-KIT
Key Product Differences
The primary variation within the series is defined by the selectable input type (RTD, TC, Ohm, mV) and configuration options. The HART® protocol version can be changed via user configuration between HART® 5 or HART® 7. Specific process connection types, wetted materials, dimensions, weight, and detailed model number breakdowns are not provided in the source documentation.
