Level Measurement & Control
The inventions of Laser Measurement's Research and Development team have increased the product range capabilities to facilitate difficult applications, eg, crushers, with no hassles. These advances have also given this South African instrument developer the opportunity to widen its horizons to new and different industries such as food and beverage and petrochemical while still focusing on the mining industry and achieving positive results in many 'thought to be impossible' applications. One of the most successful products includes the Lasermeter LM80, which is a robust, user-friendly, but sophisticated laser meter for level or positioning applications used in process control.
This unit incorporates our newly developed, more reliable software that maximises the dust penetration capabilities. The software automatically adjusts the power level on the laser to allow for the quantity of dust that it must penetrate. The new software makes the unit fast and easy to use. Setting up of this unit is made easier with simplified user menus and menu options and can also be done with Laser Measurement's new Laser Communication Device (LCD2). This device requires no batteries as it draws power from the instrument and can be used for mA setup and program selection with a display screen for convenience.
The rugged unit with strong cast aluminium housing comes with improved features such as lightning and surge protection on both the 24 V d.c. power supply and signal lines. Two mechanical relays with an output AC rating of 1A @ 120 V a.c. and 0,5 A @ 220 V a.c. or an output DC Rating of 1A @ 60 V d.c. This is an improvement on the older range, which incorporated two transistor switches instead of mechanical relays.
The LM80 is available in a 0,5 to 25 m level unit for short range applications such as crusher and bin levels, and a 0,5 to 150 m positioning unit for applications such as tripper cars, over head cranes and stacker-reclaimers. The LM80 is available as a standard environment laser transmitter or with its special adaption for hygiene conditions as well as a hot glass unit, which solves the problem of condensation on the lenses. All the LM80 Lasermeters come with a visible pointer for easy alignment. It is possible to order this unit without the pointer, which gives the client the option of a more affordable product. Laser Measurement is one of few companies who increase the performance and features of their products while still paying attention to the tight budgets of their clients and understanding their needs.
