TML Strain gauges
The main advantage of TML strain gauges are, it is roughly half the price of our competitor from US (Vishay MMG), Germany (HBK group) and Japan (Kyowa). Even though prices are less, the performance is on par with the competition which provides us decisive edge when the buyer is planning to buy strain gauges.
There are wide variety of strain gauge patterns available with TML which is used for different kind of applications and also Proact IMS keeps most of the fast-moving strain gauges in stock that the turn around time is reduced to less than 48 hours for delivery.
Their advantages stem from a 60+ year specialization in stress measurement, offering superior performance in harsh environments and specialized material testing.
Key advantages of TML strain gauges compared to other brands include:
Exceptional Environmental Resistance
TML is known for developing superior waterproof coatings and high-temperature gauges that maintain reliability in extreme conditions.
Specialized Composite & Material Gauges
TML offers unique designs, such as the UBF series, which features special grid patterns and high-compliance backings to reduce the stiffening effect on composite materials and improve fatigue life.
Integrated Pre-attached Lead Wires
Many TML gauges are supplied with lead wires pre-attached at the factory, which reduces installation time, complexity, and the risk of damage during on-site soldering.
High-Volume Customization & Specialized Options
As both a manufacturer of gauges and measuring instruments, TML offers customized designs with short lead times. They provide over 4,000 types of gauges, including specific, high-reliability models for transducers and concrete embedding.
Superior Quality Standards
TML manufactures products in a clean environment, with rigorous quality control testing (visual, resistance, gauge factor) according to international standards, including NAS 942 (National Aerospace Standard).
Wider Operating Temperature Range
Innovations like the “GOBLET” design have expanded the temperature range for general-purpose foil gauges, often exceeding typical competitive offerings (e.g., -196°C to +150°C).
High-Accuracy Transducer-Specific Gauges
TML provides specially engineered gauges for manufacturing load cells and pressure sensors that offer excellent linearity and creep characteristics, crucial for ensuring consistent, stable performance.
TML vs. Competitors
While competitors like Vishay Precision Group and HBM are industry leaders, TML often holds an edge in specialized civil engineering applications, long-term structural monitoring, and providing cost-effective, high-precision sensors for transducer manufacturing. Their focus on complete measurement systems—from the gauge to the data logger—ensures optimal compatibility.
TML Transducers
TML transducers offer several advantages, particularly in civil engineering, industrial testing, and high-precision research applications, setting them apart from competitors like HBM, Vishay, or WIKA. Their main strengths lie in specialized civil engineering durability, high-accuracy strain gauge integration, and integrated networking capabilities.
Key advantages of TML transducers include:
Superior Durability in Harsh Environments (Civil Engineering Focus)
TML is renowned for producing transducers designed to be embedded in concrete, buried in soil, or submerged in water for long-term monitoring.
- Waterproof & Robust: Many models are designed for long-term submersion or high-pressure environments, such as the PDA-PB/PDB-PB submersible pressure transducers.
- Long-Term Stability: Engineered to maintain high accuracy over extended periods for structural health monitoring (e.g., bridges, tunnels, dams).
High-Precision Proprietary Strain Gauges
Unlike brands that use third-party sensors, TML manufactures its own strain gauges.
- Optimized Sensors: TML uses transducer-specific strain gauges developed in-house to ensure high reliability and stable performance.
- High Sensitivity/Linearity: They are known for providing excellent linearity and consistency in measurements.
Integrated "TML-NET" Network System
TML offers a proprietary network system (TML-NET) which is a significant advantage for large-scale, multi-point measurement projects.
- Digital Transmission: TML-NET allows for digitized signals, preventing sensitivity degradation or cable insulation degradation over long distances.
- Easy Cabling: The network structure reduces wiring complexity for hundreds of sensors compared to traditional analog wiring.
- High Noise Immunity: Suitable for messy industrial environments with high electronic noise.
Specialized Civil Engineering Product Line
TML offers a deeper, more specialized product lineup for infrastructure monitoring compared to general-purpose sensor brands.
- Integrated Temperature Monitoring: Many TML civil engineering transducers (strain transducers, rebar meters) have built-in thermocouples/thermometers, allowing for simultaneous temperature measurement without installing extra sensors.
- Specific Applications: Specialized products like crack detection sensors, small FWD (Falling Weight Deflectometer) systems, and PC steel wire tension sensors.
Seamless Compatibility with TML Measuring Instruments
TML provides a complete “solution” package, from transducer to data logger.
- Plug-and-Play: TML transducers are designed to integrate perfectly with TML data loggers (e.g., TDS-150, TC-35N).
- Automatic Setup: Simplifies the setup process for data logging and automated measurement systems.
TML DAQ systems
TML DAQ systems are highly regarded for their specialized focus on strain, stress, and structural health monitoring, offering distinct advantages over general-purpose brands. Their primary strengths lie in high-precision measurement, rugged design, and proprietary, efficient wiring technologies that minimize errors in demanding environments.
Key Advantages of TML DAQ Systems:
Superior Strain and Structural Measurement
TML specializes in strain gauges and transducers, offering superior accuracy for structural health monitoring on bridges, dams, and machinery. Their systems, such as the TMR-300 series, provide high-resolution modes (\(0.1 \times 10^{-6}\) strain) and handle strain, voltage, and temperature inputs.
Unique 1-Gauge 4-Wire Method
TML’s proprietary measurement technology, often featured in their data loggers, uses a 4-lead wire configuration to eliminate error caused by lead wire resistance and contact resistance.
Rugged and Compact for Field Use
Many TML units, like the TMR-300 series, are specifically designed for vehicle onboard measurements, featuring high vibration tolerance, compact footprints, and the ability to operate on DC power.
Robust Data Reliability
TML loggers include built-in UPS (uninterruptible power supply) circuits and auto-restart functions to ensure data is not lost during power failures.
High-Speed & Multi-Channel Capability
TML offers fast sampling rates (up to 100 kHz) and the ability to synchronize multiple units to monitor up to 320 points, suitable for both static and dynamic analysis.
