Precision Devices, Inc. Digital Surfometer Series 400 System

Always at the forefront of technological development in surface measurement systems, Precision Devices, Inc. introduces the completely new modular Series 400.

All 400 series models utilize the same basic hardware, with model differences determined by the software installed, style of tracer and optional plotter. Starting with a basic Ra (Roughness Average) system, the units may be upgraded for future needs by simply adding parameter modules.

Simplicity is also inherent in the operation of the instrument, with prompts to guide the operator as the system gathers data, calculates the results and automatically displays the selected parameter, cutoff and system settings. The vacuum fluorescent display is bright and has a wide viewing angle, making it easy to read from any position.

Product Components

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. The 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.

Operation is at once simple, sophisticated and secure. The instrument is configured by an easy-to-use set-up menu. The user selects the proper settings for the cutoff, stroke length, standard 2RC and Gaussian filters (Rk filter optional), parameter functions, serial port and plotter operation. Set the exact stroke length required or use the standard 5-cutoffs. After setting, the programming can be secured by a turn of the lockout key, which prevents inadvertent changes. Once configured, the system operates by pressing the Start Button or through use of an optional remote start switch.

Piloters/Motor Drives

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 skidpads 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.

The Skidless Piloter

The skidless motor drive has an internal reference in the drive unit. Skidless instruments of the 400 Series are designed to evaluate small, difficult-to-reach areas that are not accessible by skid-type tracers. The motor drive is mounted on a granite base to minimize vibration and to provide a level, stable surface for locating the work piece. For more precise measurement setup, the stroke length can be set to the proper distance for the surface being measured. This is ideally suited for short stroke requirements such as grooves. This drive may also be programmed to acquire data in either direction.

The Rotary Piloter

The rotary piloter is designed to measure inside and outside diameters of parts such as balls, ball studs, and extruded tubing. The part is rotated across a stationary tracer, through an arc perpendicular to the lay. The drive, with proper tooling, will trace parts with a range from 6.35 mm to 63.5 mm (0.250 in to 2.500 in) inner or outer diameter. The amplifier will automatically adjust the speed of the rotary piloter, based upon the diameter of the measurement area, to attain a constant speed of 0.1 in/sec 2.54 mm/sec).

The piloter is able to take readings in clockwise or counterclockwise directions. It is easy to use, and can be changed from one part to another in seconds. The part can be mounted with exchangeable clamping devices.

Optional Thermal Graphic Plotter

An internal graphic plotter can be added to any of the 400 series amplifiers. The plotter is totally configurable to produce output that is appropriate to the user's needs. Plotter operation can be disabled, enabled or set for automatic plot. The user may print any combination of setup information, parameter values, roughness profile and Bearing Area Curve (BAC). The roughness profile printout has selectable horizontal and vertical magnification.

Accessories

Skid-Referenced Tracers

PDK The versatile PDK tracer, with the single SMT skidmount, can measure a 1/8 in. I.D. and O.D. to flat surfaces. The PDK has a series of standard, interchangeable double skidmounts available for most surface texture requirements.

PDM Rugged and durable, the PDM style tracer provides accurate reading throughout the surface texture measurement range. From super-fine to high micro finished, the PDM tracer offers the reliability for critical surface evaluation. Standard skidmounts permit measurements on outside diameters as small as 1/8 in to inside diameters from 1 13/16 in to flat surfaces.

Skidless Tracers

The PDG tracer does not use skids, but has various standard stylus assemblies that mount onto the tracer beam.

Other standard tracers and accessories are available based upon specific applications. If a standard product does not meet your exact need, Precision Devices, Inc. will design and build a tracer or stylus assembly that will satisfy your requirements.
