A.I. Tek Instruments Tachometers Tachpak 30 Series


AI-Tek Instruments offers fast response and high-precision tachometers for monitoring and protection of critical processes. Our prices reflect a high degree of design, quality, ruggedness, and engineering. What you really get with AI-Tek Instruments is a superb price-performance ratio.

Not all tachometers are the same, and this is certainly true of the AI-Tek Instruments tachometry line. Designed with severe industrial environments in mind, these units will provide reliable around-the-clock operation for years under adverse conditions. AI-Tek Instruments is a leader in manufacturing this type of instrument.

AI-Tek has taken its years of experience in designing and manufacturing tachometers for Military, Petro-Chem, Industrial, Rail, Power Generation, and Marine industries and put that expertise into every tachometer we make. Either TACHTROL or TACHPAK, any of the wide range of standard and custom sensors will integrate seamlessly with our tachometers.

The new generation TACHPAK and TACHTROL series tachometers have been designed with all of the functions and durability embodied in the previous tachometer series as well as improvements to extend performance, accuracy, and function.

With the exception of the Tachtrol 20, both TACHPAK and TACHTROL now share a common processing platform. This commonality allows both to perform identical tachometry functions, streamlines programming, and minimizes the learning curve.

The main physical difference between the two is the characteristic integrated display function found in all TACHTROL series tachometers.

The Tachometers Tachpak 30 Series computing tachometer is DIN rail mounted, can measure two independent speed input frequencies, convert them to relevant units that drive visual displays, mechanical & solid state relays, and analog output.

AI-Tek Tachometers are highly configurable microprocessor-based instruments that provide measuring, monitoring, and control to critical equipment. All aspects of speed sensor input signal validation, mathematical manipulation of the signal, and output control response behavior are user-defined.

Speed sensor signals are input into the tach and analyzed to be valid, mathematically manipulated into units relevant to the user then assigned to define the behavior of the display, analog output, and relays. The software program keeps safety, accuracy, and response time at the top of the task hierarchy.
