Transducer-specific strain gauges
TML gauges are not only used for strain measurement, but also as sensors for strain gauge-type transducers. Strain gauge-type transducers convert various types of physical quantities to mechanical strain in the stress-generating body (elastic body) and use strain gauges to convert mechanical strain to electric output. Strain gauge-type transducers are generally categorized into the following types.
VARIOUS TYPE OF TML TRANSDUCER-SPECIFIC SRAIN GAUGES
Single, Rectangular 2-element, Torque(Shearing) strain measurement
| Pattern | Gauge length (mm) |
|---|---|
| Single-element | 2, 3 |
| 90°2-element | 2, 3, 6 |
| Torque (Shearing strain) use | 2 |
Pattern
2 types of 90°2-element gauge are lined-up with different pattern of gauge tab. CM-type has half-bridge configuration.
| Pattern | Gauge resistance (Ω) |
|---|---|
| Single-element | 350,1000 |
| 90°2-element | 120,350 |
| Torque (Shearing strain) use | 350 |
*1000-ohm gauge has less power consumption in bridge circuit comparing to 350-ohm gauge’s and limits Joule’s heat generation.
Unlike stress measurement gauges, the gauge backing materials for transducer-specific strain gauge cannot be determined based solely on the operational temperature and bonding method. To ensure maximum transducer performance, it is necessary to test various combinations using different stress-generating bodies (elastic bodies) to select the most suitable backing materials.
Operational temperatureOperational temperature range differs from
heat-resistive temperature's.
F series gauge (with epoxy backing) is also available
for use of heat-curing type bonding adhesives.
| Gauge series | Gauge base materials | Operational temperature |
|---|---|---|
| F | Epoxy resin | -20~+80 (°C) |
| QF | Polyimide resin | -20~+200 (°C) |
| EF | Polyimide resin | -20~+200 (°C) |
The creep characteristic is particularly important in force transducers. The most common compensation system uses the material creep (+) of the stress-generating body (elastic body) and the gauge creep (-) to cancel each other. Various TML strain gauges are available for creep adjustment and are selectable by creep code.
Creep code
| Gauge creep | Large ---> Small |
| Creep code | C2>C4>C6>C8 |
