A.I. Tek Instruments Tachometers Tachtrol 10 Series

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. Our prices reflect the design, quality, ruggedness, and engineering of the equipment.

What you really get with AI-Tek Instruments is a superb price-performance ratio. It may not initially be the least expensive equipment available; but, in the long run, the value of this equipment is that it will outperform and outlast others.

The Tachometers Tachtrol 10 Series 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 Tachometers Tachtrol 10 Series 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 Tachometers Tachtrol 10 Series.

Features

• wide range of AC or DC power (12-30 Vdc, 80-264Vac 50-60Hz)
• Greatly improved instrument accuracy, processing speed, and response time.
• Frequency, period, or counter modes.
• User-defined inputs for logic level, averaging, alarm set points, and hysteresis,
• Signal normalization and math functions allow the mathematical manipulation of input signals. Results can be displayed along with user-defined units.
• Accepts sinusoidal and square wave inputs as found in variable reluctance and digital output speed sensors.
• Accepts bi-directional sensor inputs and will decode quadrature or direction signal logic
• 2 solid-state relays (fast response time) and 2 mechanical relays (high power)
• Analog output: 0-20mA, 4-20mA, -20-0-(+) 20mA (can be used with bi-directional sensor)

Application

• Fast response Overspeed shutdown
• 2 Channel Speed/Draw Monitor
• Bi-directional Tachometer
• Reverse Rotation Alarm
