Description
Micron DTI-J 4 Inch Display Temperature Indicator
The Micron DTI-J 4 Inch Display Temperature Indicator is a large-format industrial temperature indicating instrument designed for applications where temperature readings need to be clearly visible from a distance. Featuring a large 4-inch display, the DTI-J is particularly suitable for industrial plants, production floors, process areas, laboratories, testing facilities, heating systems, and other locations where conventional small panel displays may not provide sufficient visibility.
The DTI-J is designed to accept a range of commonly used industrial temperature and analog signal inputs. Depending on the factory-set configuration, the instrument can be supplied for Pt-100, J-Type, K-Type, R-Type, S-Type thermocouple, 0–1 V DC, 0–3 V DC, or 4–20 mA inputs. The required input should be specified at the time of ordering, allowing the indicator to be configured according to the particular temperature sensor or process transmitter being used.
With its large-format display and straightforward indication function, the DTI-J provides an effective solution for operators who need to observe process temperature without standing directly next to the instrument. The large display can be especially useful in environments where instruments are installed at a distance from the operator or where quick visual confirmation of temperature is required.
The instrument has a specified enclosure size of approximately 405 × 150 × 80 mm, providing a substantial display area while maintaining a practical industrial form factor. A 2.3-inch display version is also available, providing an alternative for applications where a smaller display format is preferred.
Large 4-Inch Temperature Display
The primary feature of the Micron DTI-J is its 4-inch display.
Large displays are particularly valuable in industrial environments because operators may need to monitor process temperatures from several metres away. A large numerical indication makes it easier to identify the displayed value quickly without approaching the control panel or instrument.
The DTI-J can therefore be used as a remote temperature display in suitable applications.
Typical locations include:
- Production floors
- Industrial process areas
- Heating plants
- Boiler rooms
- Furnace areas
- Manufacturing facilities
- Process control rooms
- Testing laboratories
- Warehouses
- Utility areas
The large display also makes the instrument useful as a visual process indicator where temperature status needs to be immediately apparent to operators.
Wide Range of Input Options
The DTI-J is designed to accommodate several commonly used industrial temperature inputs.
Available input options include:
- Pt-100 RTD
- J-Type Thermocouple
- K-Type Thermocouple
- R-Type Thermocouple
- S-Type Thermocouple
- 0–1 V DC
- 0–3 V DC
- 4–20 mA
The indicator is supplied in a factory-set configuration, meaning the required input type should be specified when placing the order.
This provides flexibility for different temperature measurement systems.
For example, a Pt-100 configuration can be selected for applications requiring RTD-based temperature measurement, while a suitable thermocouple configuration can be selected for higher-temperature industrial processes.
The analog input options also allow the DTI-J to receive signals from compatible temperature transmitters and process instrumentation.
Pt-100 Temperature Measurement
The DTI-J can be configured for Pt-100 RTD input.
Pt-100 sensors are widely used in industrial temperature measurement because of their stable and repeatable characteristics.
The supplied specification indicates an accuracy of:
Pt-100: 0.2% ± 1 LC
The Pt-100 configuration can be considered for applications such as:
- Process equipment
- Tanks
- Pipelines
- HVAC systems
- Food processing
- Pharmaceutical equipment
- Industrial machinery
- Heating systems
The exact temperature range should be confirmed according to the selected Pt-100 configuration.
Thermocouple Input Options
The DTI-J supports several thermocouple types, including:
J-Type Thermocouple
J-Type thermocouples are commonly used for general industrial temperature measurement.
K-Type Thermocouple
K-Type thermocouples are widely used for industrial heating and higher-temperature applications.
R-Type Thermocouple
R-Type thermocouples are suitable for specialized high-temperature measurement applications.
S-Type Thermocouple
S-Type thermocouples are also used for high-temperature industrial and laboratory applications.
The supplied specification indicates an accuracy of approximately:
J/K Thermocouple: 1%
The appropriate thermocouple type should be specified according to the application and required temperature range.
4–20 mA Process Signal Input
The DTI-J can also be factory configured for 4–20 mA input.
The 4–20 mA signal is widely used in industrial automation and process instrumentation.
This allows the DTI-J to operate as a large-format display for a compatible temperature transmitter.
For example:
Temperature Sensor → Temperature Transmitter → 4–20 mA → DTI-J
This configuration can be useful when the temperature sensor is located away from the display or when the process requires a transmitter-based measurement system.
Voltage Signal Inputs
The instrument is also specified with voltage input options, including:
- 0–1 V DC
- 0–3 V DC
- 0–10 V DC
The required input configuration should be confirmed before ordering, as the supplied information lists different voltage options in the product description and technical specification.
Voltage-output transmitters and signal-conditioning equipment can therefore be connected to an appropriate factory-set DTI-J configuration.
Clear Remote Temperature Indication
The DTI-J is particularly useful when the temperature needs to be visible without requiring the operator to approach the sensor or process equipment.
For example, in an industrial production area, the temperature sensor may be installed inside a machine, oven, chamber, tank, or pipeline. A large-format DTI-J display can be installed at a convenient viewing location.
This arrangement provides:
- Convenient temperature visibility
- Faster operator monitoring
- Easier process observation
- Reduced need to approach machinery
- Centralized temperature indication
Industrial Applications
The Micron DTI-J can be used across a variety of industries and processes.
1. Manufacturing
For displaying temperature from industrial machines, heating systems, and process equipment.
2. Industrial Ovens
The large display can provide convenient visibility of oven temperature from outside the equipment area.
3. Furnaces
Suitable factory-configured thermocouple versions can be used for appropriate high-temperature monitoring applications.
4. Food Processing
Can be considered for suitable temperature monitoring applications in processing and production equipment.
5. Pharmaceutical Industry
Can be used for suitable process and equipment temperature indication, subject to application-specific requirements.
6. HVAC
Suitable configurations can be used for remote temperature indication in heating, ventilation, and air-conditioning systems.
7. Process Plants
The 4–20 mA version can be used with compatible process transmitters for large-format remote indication.
8. Laboratories and Testing
The large display can be useful where temperature needs to be easily observed during testing or experiments.
2.3-Inch Display Option
In addition to the standard 4-inch display, a 2.3-inch display version is also available.
This provides flexibility for customers who require a smaller display format or have space limitations.
The appropriate display size can therefore be selected according to:
- Viewing distance
- Panel space
- Installation environment
- Required visibility
- Application requirements
The 4-inch version is particularly suited to applications where long-distance visibility is important.
Industrial Power Supply
The DTI-J is specified for operation with:
230 V / 110 V AC ±15%
This allows the instrument to be used with commonly available industrial AC supply systems, subject to the ordered configuration.
The appropriate supply requirement should be selected and confirmed during ordering.
