DeFelsko is excited to announce a new probe for the PosiTector SPG Surface Profile Gage series. The PosiTector SPG OS probe is ideal for measuring the peak-to-valley surface profile height of convex abrasive blast cleaned surfaces such as pipes and tanks.

The new PosiTector SPG OS features two operating modes — OD (Outside Diameter) Mode (default) and Normal Mode. In OD Mode, the PosiTector SPG OS uses a proprietary sampling process to analyze multiple measurements for greater accuracy on convex surfaces. In Normal Mode, the instrument operates similarly to the PosiTector SPG and PosiTector SPG S making it ideal for flat surfaces too.
The PosiTector SPG OS probe features an integral V-groove and optional Large V-groove Adaptor to assist with proper probe positioning on cylindrical parts. Simply align the V-groove along the axis of the curved surface using the notches on the probe face and/or the indicator arrows on the face of the adaptor.
The optional Large V-groove Adaptor is available to assist with probe placement when measuring on pipes or tanks with an OD between 30 cm (12") and 46 cm (18").

The NEW PosiTector SPG OS is compatible with any Standard PosiTector gage body with a color display and any Advanced PosiTector gage body with S/N 730,000+.
NEW PosiTector SPG OS probe features
  • Ideal for measuring on flat and curved surfaces with an OD greater than 3mm (0.125")
  • Proprietary OD Mode analyzes multiple measurements for greater accuracy on convex surfaces
  • Normal Mode is ideal for flat surfaces, and operates similarly to the PosiTector SPG and SPG S probes
  • Self-leveling probe foot ensures perpendicularity to the part being measured
  • Uses the proven V-groove design found on PosiTector 6000 coating thickness probes to stabilize the probe on any diameter
  • Available Large V-groove Adaptor for enhanced stability on 30 – 45 cm (12 – 18") OD pipes
All PosiTector SPG probes feature
  • Durable alumina wear face for long life and continuous accuracy
  • Standardized 23 mm/0.9 in diameter probe foot with 340 mm2 (0.5 in2) surface area
  • Field replaceable tungsten carbide probe tips
  • Conformance to international standards including ASTM D4417-B, SSPC-PA 17, AS 3894.5-C (with optional 30° tip angle), US Navy NSI 009-32, SANS 5772 and others

Q & AEmy帝国网站管理系统

Q: Why does the finger grip sleeve on the PosiTector SPG OS feel loose?
A: The PosiTector SPG OS is designed with a self-leveling probe foot to ensure perpendicularity to the part being measured. The finger grip sleeve needs to have a loose fit in order for self-leveling to work.

Q: What is the benefit of the optional Large V-groove Adaptor?
A: The Large V-groove Adaptor offers enhanced stability on 30 – 45 cm (12 – 18") OD pipes and helps with proper positioning and measuring technique. The adaptor should not be used on pipes greater than 46 cm (18”).

Q: Can I compare readings from a PosiTector SPG OS with readings from a PosiTector SPG or SPG S?
A: On flat surfaces, the PosiTector SPG, SPG S, and SPG OS probes will measure similarly. However, measurements taken by the PosiTector SPG OS (or any depth micrometer surface profile instrument) on rounded surfaces should only be compared with measurements taken on surfaces with a similar radius. On flat surfaces, the probe foot contacts the substrate over its entire area, while on curved surfaces the probe foot contacts an increasingly smaller area as the radius decreases. This may cause a slight decrease in the reported peak-to-valley surface profile height, since the probe foot sits on fewer peaks as the contact area decreases.
