Description
Micron FLP-DTI Flame Proof Temperature Indicator Without Glands
The Micron FLP-DTI Flame Proof Temperature Indicator Without Glands is a robust industrial temperature indication instrument designed for temperature monitoring in hazardous and potentially explosive industrial environments. It is specifically developed for applications where temperature measurement equipment must be installed within a flameproof enclosure suitable for classified hazardous areas.
The FLP-DTI is designed for use with a Pt100 RTD input and is available with temperature ranges of 50 to 400°C or -50 to 400.0°C, depending on the required application. The flameproof enclosure provides a protective housing for the temperature indicator, helping prevent ignition-related hazards associated with electrical equipment installed in potentially hazardous environments.
According to the supplied specification, the flameproof enclosures are CMRI certified for Gas Groups I, IIA and IIB. This makes the instrument suitable for selected hazardous-area applications where combustible gases, vapours, or other potentially explosive atmospheres may be present.
The “without glands” configuration allows users to select and install cable glands appropriate to their specific hazardous-area installation requirements. This can be particularly useful for OEMs, instrumentation contractors, panel builders, and industrial plants that have standardized hazardous-area cable-entry systems.
The Micron FLP-DTI is suitable for industries such as oil and gas, petroleum, petrochemical, chemical processing, refineries, gas handling, hazardous manufacturing areas, and other industrial facilities where reliable temperature indication is required.
Flameproof Temperature Indication for Hazardous Areas
Temperature measurement is an important part of industrial process monitoring. In hazardous locations, however, the temperature indicator must be appropriately designed for the environment in which it will operate.
The FLP-DTI combines a Pt100 temperature input with a flameproof enclosure, providing a practical solution for displaying process temperature at or near the measurement point.
The enclosure is designed to contain potential internal ignition events and help prevent them from becoming an ignition source outside the enclosure, subject to the applicable certification, installation requirements, and hazardous-area classification.
CMRI Certified Flameproof Enclosure
The supplied specification states that the flameproof enclosures are CMRI certified for Gas Groups I, IIA and IIB.
This certification is an important feature for applications where equipment is installed in hazardous industrial locations.
The supported gas groups cover a range of industrial hazardous-area applications. However, users should always verify that the exact certification, area classification, gas group, temperature class, installation method, and local regulatory requirements are appropriate for their particular site.
The certification should not be interpreted as approval for every hazardous location. Selection must be based on the complete hazardous-area classification and applicable statutory requirements.
Pt100 Temperature Input
The FLP-DTI uses a Pt100 RTD as its temperature input.
Pt100 is one of the most commonly used industrial resistance temperature detectors because of its stable and repeatable temperature measurement characteristics.
The resistance of the Pt100 sensor changes predictably with temperature, allowing the indicator to determine and display the corresponding process temperature.
Pt100 sensors are widely used in:
- Process plants
- Oil and gas facilities
- Refineries
- Chemical plants
- Petrochemical plants
- Heating systems
- Storage tanks
- Process vessels
- Pipelines
- Industrial machinery
The use of Pt100 makes the FLP-DTI suitable for a broad range of industrial temperature monitoring requirements.
Available Temperature Ranges
The Micron FLP-DTI is specified with two temperature range options:
Option 1: 50 to 400°C
This version is suitable for applications where the normal operating temperature is above ambient and falls within the specified high-temperature range.
Option 2: -50 to 400.0°C
This wider-range version can be used for applications involving both sub-zero and elevated temperatures.
The appropriate range should be selected according to the process requirements when ordering.
Suitable for Oil & Gas Applications
The FLP-DTI is particularly relevant to hazardous industrial environments found in the oil and gas sector.
Potential applications include temperature monitoring associated with:
- Oil processing systems
- Gas processing equipment
- Refineries
- Petrochemical plants
- Storage facilities
- Process vessels
- Pipeline systems
- Fuel handling systems
- Pumping stations
- Hazardous-area machinery
In these environments, temperature indication can provide important information for process monitoring and operational safety.
Petrochemical and Chemical Industry
Chemical and petrochemical facilities often contain areas where flammable gases or vapours may be present.
The FLP-DTI can be considered for appropriate temperature indication applications in such environments, provided that the equipment’s certification and temperature classification meet the requirements of the installation.
Typical applications may include:
- Reactors
- Process tanks
- Heating systems
- Distillation-related equipment
- Chemical processing systems
- Storage vessels
- Process pipelines
Without Cable Glands Configuration
The product is specified as a flameproof temperature indicator without glands.
This means the cable glands are not included as part of the supplied configuration.
The advantage of this arrangement is that the end user or installation contractor can select suitable cable glands based on:
- Cable diameter
- Cable type
- Hazardous-area classification
- Enclosure certification requirements
- Site installation standards
- Applicable electrical regulations
For hazardous-area installations, cable glands are an important part of the overall protection system. Only appropriately certified and compatible glands should be selected and installed according to the relevant hazardous-area requirements.
Robust Industrial Enclosure
The flameproof enclosure provides mechanical protection for the temperature indicator and its internal electrical components.
It is intended for demanding industrial environments where equipment may be exposed to:
- Industrial dust
- Process contamination
- Mechanical handling
- Temperature variations
- General plant conditions
The enclosure also provides a practical housing for local temperature indication.
Local Temperature Monitoring
One of the advantages of a flameproof temperature indicator is the ability to provide local process temperature indication.
Instead of relying exclusively on a remote control room display, operators can inspect the temperature at the equipment location.
This can be useful during:
- Routine plant inspections
- Equipment commissioning
- Maintenance
- Troubleshooting
- Process verification
- Field monitoring
Local indication can complement centralized PLC, DCS, or SCADA-based monitoring systems.
Applications
The Micron FLP-DTI can be used in suitable hazardous-area applications across several industries.
1. Oil & Gas
For temperature indication in selected classified areas of oil and gas facilities.
2. Refineries
Suitable for local temperature monitoring around process equipment where the applicable hazardous-area requirements are met.
3. Petrochemical Plants
Can be used with Pt100 sensors for monitoring process temperatures.
4. Chemical Plants
Suitable for selected hazardous process areas.
5. Gas Processing
Can be applied to temperature monitoring equipment associated with gas handling and processing.
6. Fuel Storage and Handling
Suitable for appropriate temperature indication points in hazardous storage environments.
7. Industrial Process Plants
Can be incorporated into process instrumentation systems where flameproof construction is required.
