Hard Gage Calibration



More Views

FVM and Twin Pines Metrology, divisions of WESTport Corporation use state of the art equipment to ensure the highest degree of measurement uncertainty. With this equipment, and our custom-designed software, we are able to offer you the best possible turnaround time, and pricing in the industry. The hard gage calibration lab is held at 68°F with relative humidity not to exceed 45%. Both temperature and humidity are closely monitored by our Honeywell environmental control unit. We also have a suspended floor to help avoid unnecessary vibration and ensure a good measurement uncertainty of all of our equipment.

When your gages come into our ISO/IEC 17025 accredited hard gage lab, they have already been thoroughly cleaned and inspected for shipping damage. Gages sit in the lab for 24 hours in order to acclimate to the proper laboratory conditions. When the gages are calibrated, they are also closely inspected for nicks, burrs, and corrosion; then re-cleaned and stickered. When packaged for return, gages are either coated in dip-seal, or oiled and wrapped in bubble wrap, and boxed securely. Calibration pricing includes cleaning, and level 4 certification. Average turnaround time is 1-3 days.

Pratt and Whitney Supermicrometer

The Pratt & Whitney Supermicrometer has a 10 inch travel and a measurement uncertainty of 17µin over 1 inch of travel. It is extremely accurate for thread gaging. With a RS232 output that is directly networked to our software, we are capable of entering data at the touch of a button. Some capabilities include thread plugs, thread setting plugs, thickness gages, and length standards.

The Series 400 Amplifier
The Series 400 Amplifier is a sophisticated yet easy to use instrument with a modular surface texture program. All models feature a vacuum fluorescent display and sealed membrane keypad. An RS-232 communication port is standard (RS-485 optional), along with a remote start switch port and lockout key switch. Battery power is included on all models with the graphic plotter, and is optional on all other models.


The Skid-Reference Piloter
Skid-referenced systems are designed to measure normal I.D., O.D., and flat surfaces. The skid-referenced motor drive (piloter) contains a motor which moves the linkarm with the tracer across the surface to be sampled. The tracers have skid pads which establish a reference line. The transducer translates the vertical motion of the diamond tip stylus in relation to the reference line. The piloter traverses at a speed of 0.1 in/sec (2.54 mm/sec) for the travel length specified and can be set to acquire data in either direction. Our patented Lite-Touch Linkarm protects the tracer and surface from inadvertent damage and comes standard with each system, unless otherwise specified.
