Strain gauge-type civil engineering transducers made by TML use strain gauges as detecting sensors. These transducers measure concrete strain, soil pressure, water pressure, stress, displacement, inclination, and other various physical quantities and convert them electrically. They are designed to deliver the best performance for many different applications and to maintain superb sensitivity, accuracy and durability over a long period of time. If they are used in combination with data loggers supplied by our company, it is possible to build an automated multi-point measurement system that operates unattended to gather data for a long time. TML civil engineering transducers are now the indispensable components used to conduct experiments on or pursue research for general buildings, bridges, ground, tunnels, dams and other civil engineering structures. They also play an important role in predicting disasters, developing new construction techniques, and preparing safety designs for such mass-transport means as railways, vehicles, ships and airplanes.

Civil Engineering Transducer with Temperature measuring functionsTemperature measurement is an essential part of strain and stress measurement in concrete structures. The strain transducers and reinforcing-bar meters in the line of strain gauge-type civil engineering transducers made by TML all have built-in temperature measuring capability that can be used to measure temperature without having to install a thermometer. As a result, measuring temperature with a Data Logger is quick and simple. A choice of available measuring methods between a special strain gauge and a thermocouple allows customers to choose the most appropriate method for the particular purpose and the type of Data Logger used.

Strain instruments with constant voltage and Constant current method
Constant voltage type
The bridge power supply in our rated voltage-type strainmeter ensures a constant voltage regardless of the input resistance of any connected transducer. Even so, the sensitivity of the transducer will drop due to wire resistance in the connecting cable if the transducer cable is extended.Constant current type Current form the bridge power supply to the transducer remains constant with our constant current-type strainmeters regardless of the input resistance of the transducer or the length of the cable (wire resistance). Therefore, the sensitivity of the transducer will not drop due to wire resistance in the cable if the transducer cable is extended. However, there is a limit on the input resistance of the transducer.

Transducer bridge circuit and connector alignmentBridge circuit inside and wiring system are given as follows, but not applicable to some products. Standard civil engineering transducers are usually supplied without connector plug. When connector plug is required, specify it on order to install the plug to the transducer cable.
