1. Introduction

AI-TEK TACHTROL 10 &30 (TT) and TACHPAK 10 & 30 (TP) series instruments are

dual input, industrial tachometers used to measure the rate of events from a given

process. Using the proportional signal outputs from either passive or active sensors, TT

and TP can measure, monitor and react to events as simple as the speed of a shaft, or as

complex as relating the differential in speed of 2 independent rotating objects.

TACHTROL

plus

provides additional function as a remote display and also serves as a

gateway for secure, remote programming. Both TT and TP share a common processing

platform. This commonality allows both to perform identical tachometry functions,

streamlines programming and minimizes the learning curve. The main difference

between the two is the characteristic integrated display function found in all TACHTROL

series tachometers.

1.1. Overview

A speed sensor placed near a moving target such as a rotating gear generates a

series of pulses whose frequency is proportional to the speed of the target. This

information is utilized by the tachometer as the basis for its function. Some key

features are as follows. See specification section for specific model and option

applicability.

• Wide range of AC or DC power

• 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 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)

• Two programming methods: Front panel on display or USB2.0 connectivity to

TACHLINK, a PC / Windows-based GUI (Graphical User Interface). The

GUI can be used to display data, program, perform security functions,

diagnostics, analog output calibration and real-time data logging.

• In the case of tachometer instruments embedded in explosion proof or NEMA

4X enclosures, remote access solves the problem of programming by making

use of an IR link to allow full front panel control via a hand-held remote.

• Utility RS485 communication also allows full GUI function but over longer

distances (up to 8000 ft)
