Measurement Consulting
Measurement Consulting
In the measurement business until now, there are many measuring methods which place importance on measurement done in the past, and inevitably, the latest technology is not in the process, such as cases where optimal pricing is not considered. While giving importance to conventional measurement methods, our measurement consulting goes on to take both site conditions and technology advancement into consideration in real time, allowing us to draw up a plan, project phases, and study that meet the needs of the client with the particular project, and to make a proposal that meets not only technological requirements, but budgetary ones as well. In addition to a measurement project and proposal, we also build a measurement system compatible with ubiquitous networking, and in some instances we may go beyond primary processing of measurement data (physical quantities conversion) onto secondary data processing (evaluation) so as to meet client needs.
We will propose a management and measurement system that utilizes information and communication devices in order to achieve more efficient measurement.
See [Home > Field sites] for case studies where measuring systems have been introduced in different kinds of construction projects.

MEASURING SERVICE
We can put together a measuring process that is optimized for your measurement goals and what is involved.
Obtaining correct measurement data is not necessarily an easy task. Reliable information is gained only by a correct process that is suited to the measurement goals and type of structure. We determine these correctly for the characteristics of the subject being measured and location conditions, and then proceed from site visiting to all aspects of measurement including creation of measurement plan, placement of equipment, measurement, data recording/processing, and onto creation of a report. We carry out a range of measurement activities, always giving attention to details in handling and service, making use of our expertise and experience.

Frictional Torque Sensor System Frictional Type Torque Sensor System FGDH-3A
Frictional Type Torque Sensor System
FGDH-3A
Frictional type torque sensor system FGDH-3A employs a frictional-type gauge does away with having to adhere a strain gauge and time-consuming connection of lead wire. IT measures torque occurring at the drive shaft of an automobile and sends the digital data wirelessly. It uses the 2.4 GHz range of the wireless range for long-range communication and easy receiving antenna locationing. The sensor clamps around the shaft and screws down easily. Applicable shaft diameters are ø20 to 30 mm, ø30 to 40 mm, and ø40 to 50 mm. Power supply uses a USB power cable with recharging capability, so the sensor can be recharged without needing to be removed.
[Patent registered]
- Features
- 2.4 GHz band is used for wireless communication
- Three types available for applicable shaft diameter of 20~30, 30~40 and 40~50 mm
- No bonding is required because frictional strain gauges are used
- Measurement possible immediately after clamping on the drive shaft
- Digital communication system adopted for noise-resistant measurement without wiring
- Easy-to-use rechargeable power source
- Power saving function provided
