Fewer errors and simpler measurement with a new leveling instrument

Fewer errors and simpler measurement with a new leveling instrumentKeywords: Laser sensors, Measurement

Newly launched is an aluminum dual grade laser, the Ama Laser DL, which is said to be the only leveling instrument on the market with separate displays for x and y grades, which will reduce the risk of errors and ease measurement (Plate 16).

The integrated handle and low weight make this measuring instrument – which is also claimed to be both shock proof and watertight – easy to carry around. Built-in rechargeable batteries will reduce operational problems.

Plate 16 This new leveling instrument, the Ama Laser DL, uses visible red light for safety, and is said to be the only leveling instrument on the market with separate displays for x and y grades

The instrument is a rotating, self-leveling diode laser with grade settings in two planes and visible red light. It is manufactured by the Swedish company Ama Laser Systems AB. The company's managing director, Fredrick Nilsson, says:

We think that rental companies and the larger construction and pipe-laying enterprises need an easily-used and reliable all-round instrument that everyone can use. This instrument can be used by major companies – such as those carrying out construction, pipe-laying and infrastructure projects – but also for simpler marking out.

No need for on-site instruction

The x and y grade displays are positioned at right-angles to each other in a design similar to the AC1 pipe-laying laser instrument from the same company.

"This makes its use simple and intuitive, and rental company employees will now be able to avoid going out to explain how the instrument works," hopes Fredrik Nilsson. The product is based on proven technology in respect of its motors, mechanism and electronics.

Despite having new functions the Ama Laser DL is not any more expensive than its predecessor, the Multi-Laser 4000. Software for the control functions can be downloaded from a PC, without needing to open the instrument, which can also be supplied with a remote control.

Unlike its competitors, who fit exchangeable battery packs, the company has chosen to use built-in batteries with an operating time of 60-70 hours and a recharging time of about six hours. Many operating problems are caused by damp and dust entering instruments when battery packs are changed

The thick aluminum case ensures the unit is robust, and every product is tested to guarantee continued accuracy even after severe impacts The sealing is also tested, and the instrument is filled with nitrogen to protect the optics against damp.

The Ama Laser DL is capable of being used in temperatures between –4 and +122 degrees, without reducing its measuring accuracy of ±5mm per 100m. The grade accuracy in the x-plane is –5 to +20 per cent and in the y-plane –7 to 7 per cent, which should cover most measurement situations The instrument even has a built-in folding stand, which permits setting of the whole x-plane range without additional accessories
