Rope Testers
-
The LMA Signal measures loss of metallic cross-sectional area (LMA) caused by corrosion, abrasion, etc. The LMA Signal is quantitative and can be calibrated. (Typically, a rope must be retired when the LMA exceeds 10%).The WRR Signal measures wire rope roughness (WRR). WRR is defined as the aggregate surface roughness of all wires in a rope. WRR is typically caused by and indicates internal and external corrosion pitting, broken wires and clusters of broken wires. The WRR signal is quantitative, and it is calibrated together with the LMA Signal.The LF Signal can indicate localized flaws (LF), for example, broken wires, corrosion pitting, etc. Because it is only qualitative - and cannot be calibrated - it is of limited value for assessing rope deterioration and for making rope retirement decisions.

The voltmeter included in the kit, the “Model DPM” voltmeter, is designed for ease of use by meter readers and corrosion technicians alike and the voltmeter comes with an integrated RE-5 reference electrode attached for “metallic structure-to-soil” potential difference readings. The kit also includes a special test lead that has a brass thumb screw on one end which allows the test lead to substitute for the RE-5 reference electrode. This substitution allows the voltmeter to take “structure-to-structure” potential difference readings. The voltmeter offers two ranges, ±2VDC and ±20VDC with a 20MΩ input impedance. Since the voltmeter is digital [in contrast to the meter in our analog tank test kit (Cat. # 4108)], both negative and positive voltages are displayed. `

Atlas Material Testing Solutions
It is not practical to determine the weathering characteristics of materials in all of the world's climates. Therefore, benchmark climates selected for exposure testing are based on their known severity for the weathering of materials and the anticipated market of the product. The major marketing area of the material should be taken into consideration when selecting suitable climates and sites for weathering tests. Each class of materials is sensitive to a specific group of environmental parameters. Humidity, rain, and salt spray can cause corrosion of metals. For plastics and coatings, ultraviolet radiation, temperature, and moisture can initiate material degradation.
