AI-TEK Tach-Pak 3 - Digital Process Tachometer - NonIndicating

The AI-TEK Tach-Pak 3 computing tachometer is a single channel instrument. It measures input frequency and converts the resulting quantities to a meter output, an analog output and four relays.  The microcomputer based Tach-Pak 3 permits a combination of fast response and high accuracy.  The instrument functions can be easily programmed in the field or altered at any time using a unique internal switch design.

Typically, this instrument is used with magnetic sensors as a signal source.  However, it may receive a sine wave or TTL signal from any frequency source.

 

Quick Response - 50 ms updates above 100Hz High accuracy.  =/-.5% for analog outputs & +/- .05% for relay setpoints. Field Programmable - No additional calibration required AC or DC Power

Digital Configuration - Utilizes adaptive period averaging & floating point calculation 2 Analog Current Outputs 0-1ma, 0-20ma, 4-20ma. 4 relays - Sealed 6 amp SPDT auto reset or latching CSA Listed

AI-TEK Tachtrol 2 - DISCONTINUED - Call (800) 576 - 6308 or Email for replacement model(s).

The AI-TEK Tachtrol 2 speed/rate monitor is a single channel digital indicator.  It displays measured values in engineering units: RPM,FPM, frequency or other values.  This is an indicator only and does not have any outputs.

AI-TEK Tachtrol 3 - Dual Input Indicating Digital Tachometer

The AI-TEK (Airpax) Tachtrol 3 computing tachometer is a single or dual channel instrument. It measures input frequencies and displays the resulting quantities in RPM, FPM, %Draw or other rates.  Measurement using the period mode (time per event) permits a combination of fast response and high accuracy.

AI-TEK Split & Solid Gears  - Click Here to access detailed info on all products.

Split Gears When using an AI-TEK speed sensor in RPM measurement, split gears provide a convenient and simple means of installation where shaft disassembly is not feasible.  The two halves of the gear are fastened with clamping screws, thus assuring close fit.  All split gears are 12 diametral pitch, 14.5 degree pressure angle.

Solid Gear FLW also offers a 20 diametral pitch, 14.5 degree pressure angle, solid steel gear.  This gear can be rebored to fit shaft diameters up to 1.375".  It is secured to the shaft with 2 set screws.

Tachometer Tape - Click Here to access detailed info on all products.

Model TT Tachometer Tape provides speed and frequency measurements from a magnetic pickup when only a smooth shaft or wheel is available. Tachometer Tape is a slotted, 1-inch (2.54 cm) wide, 1/16 inch (0.16 cm) thick strip of flexible magnetic polymer. Pressure sensitive adhesive on back side allows fastening to a smooth shaft.  Minimum shaft diameter: 2 inches (5.08 cm).

To calculate length required:	click for larger photo
1) Determine shaft circumference
2) Determine number of discontinuities by dividing circumference plus 2 in (for overlap) by 0.45
Price:  $36/12inches
