WWiirree--wwiirreelleessss ffuullll ssccaallee ddaattaa llooggggeerr((AARRFF--110000)) is wire-wireless data logger that have 2.4GHz transmission-reception function of ZigBee communication. ARF-100 can connect with all VW sensor, mA sensor, mV sensor.Full scale data logger is based on the wireless. ARF-100 can connect MUX & Data logger, andMUX & MUX in parallel. You can select a wire or a wireless. Our ARF-100 is quite useful in largeproject fields that need cabling such as tunnels, soft ground, big structures and harbors or damconstruction field that need permanent measurement being required.Since it is not subject to legal restrictions or type approval because it uses commercial frequencyof less than 2.4GHz/10mW, this is next-generation monitoring system that automaticmeasurement is possible just after network configuration.In case of installing as the wireless, to transmit and to receipt a maximum 600m is possible by selecting of theantenna. And in case of using the RF repeater, the notice distance can be extended more than twice.

Model AACCEE--TTCCSS--EE is very useful to recognize convergence scale, inclination or proportion of anytunnel or under excavation work. It consists of a tilt sensor with X&Y at both ends of tunnel, adisplacement sensor, mounting bracket and an extension tube as a kit. Its gage is installed alongwith internal wall of tunnel by 1-2m not to hinder transportation service. ACE-TCS-E perfectly coversthe tunnel displacement with its mounting bracket and extended extension tube. ACE-TCS-E semiautomatically operates after contacting signal cables of tilt sensor and displacement sensor to theterminal box or you can control and automatically measure in long distance with data logger.

MMooddeell 22335500DD ttaappee eexxtteennssoommeetteerr is mainly used to quickly and accurately measure smalldisplacement between both walls, which are in opposite sides in excavation, tunnel, andmine’s open-cut section, or between crown side and bottom side. Besides them, it is alsoused to measure deformation of a structure or a support or to measure movement ofunstable slope. Digital tape extensometer consists of a steel tape, a tension adjustingsleeve, a moving hook used in adjusting tension, and a digital gauge’s scale.

Model 11334455 is mainly used to understand any changes in size, ratio and tendency of tunnel,caused by constructing tunnels or underground structures.The main body of VW convergencementer is made of strong stainless material. The key products are composed of sensor part, stainless extension load and hook. It is a preciseinstrument, which measure inner section between 2 points by placing hooks at both sides' ends.

The VVWW rroodd eexxtteennssoommeetteerr is useful to measure of displacement of ground by convergentexcavation in the ground like tunnel, mind, or common duct and to measure deformation ofslope and horizontal or vertical displacement of soil or rock in tunnel.It has sensor part built with 4 of small VW displacement sensor which is water proofed, anchor forgrouting treatment of tunnel base rock, and anchor rod made up of glass fiber to deliver displacementto sensor. Rod and anchor should be treated with grouting in the hole of perforation.Model 11339911 is VW rod extensometers whose point distance is over 6m and is designed into astructure that is possible to assemble and establish in the construction site.

EELLSS rraaiill ttrraacckk mmoonniittoorriinngg ssyysstteemm can precisely measure any settlement or wrenching ofrails on railroad tracks. The gage that is installed parallel with the rail consists of each tilt sensor for measuringsettlement and wrenching, a kit of mounting bracket, extension tube. It is installed parallelalong with between rails and has 2~3m length, which is bigger than the excavation work notto hinder transportation service. With any transformation on a railroad bed, the placed angleof tilt sensor as much as the changed amount of influenced X-axis. The angle of the sensorchanges along with any change of sinking or rising of Y-axis to measure the length direction.We can also diagram the displacement value as graph use in RTM-PRO.

Model 11335500 VVWW rroocckk bboolltt ssttrreessssmmeetteerr is used to verify validity such as effective length,quantity and stress of rock bolts. It also is equipped with four VW strain gages, each otherequally spaced in the rock bolt, and is water proof and anticorrosive.VW strain gages inside the rock bolt detect stress caused by behavior, slack and cuttingtransmitted to anchors. The VW rock bolt stressmeter employs typically four measuringpoints that is equivalent to layers. Also it is equipped with the accurate thermistor forcompensating temperature variations and is available 2 to 6 meters anchors in rock bolt.The VW rock bolt stressmeter do not affected by contact resistance and induced voltage forelectrical sensors, bringing on an unstable reading.

Model 11665500 VVWW WWeeiirr mmoonniittoorriinngg ssyysstteemm employs a VW force transducer and is sensitive to

water level.

This consists of the VW transducer, a cylindrical buoy. assembly to detect water level, and a

chamber to inject water. Water level in a chamber serves as buoyancy that is equal to

adjacent water level.

Changes in buoyancy on the buoy assembly caused by water level, change tension of the

vibrating wire.

When using it under weir monitoring system on the dam site. You have to apply them to

accessories on V notch, wave filter and discharge weir and the size or installing place has to

be consulted beforehand.

Model 77550000 is a optical meter for civil engineering works such as tunnel or excavating underground.There are a triple prism and bireflection target for a light wave target.Triple prism is a processed crystal with a high degree. As it makes use of refraction of light, it showshigh reflexibility and allows increasing the range of force up to 500m. Though it allows measuring3D, it requires special caution on potential damage if not readily dealt with the condition of the site.Bireflection target uses high brightness for displacement and thus its accuracy is lower than tripleprism and its range of force is up to 100m. As it allows for 2 dimension measurement, it is veryhandy for civil engineering works such as tunnel and its price is very low compared to prism.
