Motion & Speed Measuring Instruments
High quality Motion & Speed Measuring Instruments designed for accurate measurement of rotational speed, linear motion, velocity, and acceleration across industrial, marine, automotive, and inspection applications.
Overview
Motion and Speed Measuring Instruments are used to measure the movement, rotational speed, linear velocity, and acceleration of mechanical systems and moving objects. These instruments are essential for monitoring performance, ensuring safety, and maintaining accuracy in industrial, automotive, marine, and inspection environments.
Rotational Speed Measurement
A tachometer is one of the most widely used motion measuring instruments. It is designed to measure the rotational speed of a shaft, motor, or rotating disk, typically expressed in revolutions per minute (RPM). Tachometers may operate using mechanical contact, optical sensing, magnetic pickup, or electronic signal processing.
Rate & Totalization Functions
In addition to RPM measurement, many tachometers also function as rate meters or totalizers, allowing users to track cumulative rotations, operating hours, or production cycles. This data is critical for maintenance planning and performance analysis.
Marine Speed Measurement
Pitometer logs, also known as pit logs, are specialized instruments used to measure a vessel’s speed relative to the surrounding water. These devices are used on both surface ships and submarines, with measured data typically integrated directly into the vessel’s navigation and control systems.
Velocity & Acceleration Measurement
Motion and speed measurement extends beyond rotation to include linear velocity and acceleration. Instruments designed for these applications are used to measure traveling speed, wind speed, machine feed rates, and acceleration in dynamic systems.
Speed Detection Technologies
Different technologies are employed depending on the application. These include mechanical sensing, optical detection, magnetic pickup, ultrasonic measurement, and radar-based systems. For example, law enforcement agencies commonly use RADAR and LIDAR instruments to measure vehicle speed with high accuracy.
