3. Working Principle of the Bimetal Thermometer MT-T110BM
The Bimetal Thermometer MT-T110BM operates on a bimetallic strip principle, where two metals with different thermal expansion coefficients are bonded together. Temperature changes cause the bimetallic strip to bend proportionally, and this mechanical movement is transferred to a pointer that moves across the dial face.
Benefits of the bimetal mechanism:
-
Accurate, linear temperature readings
-
No electricity required, enhancing safety
-
Simple and robust design suitable for harsh industrial conditions
-
Minimal maintenance requirements
This makes the MT-T110BM a durable and reliable choice for continuous industrial temperature monitoring.
4. Dial Visibility and Readability
The dial sizes 100DN, 125DN, and 160DN allow operators to select the most suitable size for their application:
-
100DN: Compact installations, limited panel space
-
125DN: Medium visibility for mid-range installations
-
160DN: Large-scale readings for panels or distant observation
The dial is designed with high-contrast numerals and pointer markers, ensuring precise readings even in low-light or high-glare environments. The scale is calibrated to provide clear visibility, minimizing reading errors during critical processes.
5. Stem Construction and Temperature Range
The MT-T110BM features a 6.0 mm diameter stem, available in lengths from 25 mm up to 2000 mm. This flexibility allows the thermometer to be inserted into various process pipes, tanks, and machinery for direct temperature measurement. The long stem options ensure the sensor reaches the optimum measurement zone, providing more accurate readings for fluid or gas processes.
The thermometer’s temperature range of -70°C to 600°C allows it to cover:
-
Cryogenic systems
-
Heat exchangers
-
Boilers and steam pipelines
-
Chemical reactors
-
HVAC and refrigeration systems
This wide operating range ensures versatility for multiple industrial applications.
6. Back Direct Mounting and Adjustable Process Connection
The back direct mounting pattern allows the MT-T110BM to be installed directly into panels, enclosures, or machinery. The adjustable process connection ensures that the dial can be rotated or aligned for optimal visibility after installation, making it user-friendly for maintenance and operational checks.
The ½” NPT (M) threaded connection provides secure and leak-proof integration with standard thermowells or pipelines. This flexibility reduces installation complexity and ensures accurate, repeatable temperature readings.
7. IP65 Protection and Environmental Durability
The MT-T110BM is rated IP65, offering dust-tight protection and resistance against low-pressure water sprays. This rugged construction ensures reliability in outdoor installations, industrial plants, and environments exposed to dust, moisture, or corrosive atmospheres.
The thermometer is engineered to perform consistently in:
-
Industrial chemical plants
-
Outdoor heating or cooling installations
-
Water and wastewater processing plants
-
Food processing and pharmaceutical production lines
Its durable construction ensures long-term reliability and minimal maintenance.
8. External Zero Adjustment for Calibration
A standout feature of the MT-T110BM is the external zero adjustment, which allows technicians to recalibrate the thermometer without disassembling it. This capability ensures:
-
Accurate readings over time
-
Quick correction of any minor pointer deviations
-
Simplified maintenance procedures
-
Reduced downtime for industrial processes
This feature enhances operational efficiency, especially in high-precision applications where even minor deviations can affect process outcomes.
