KTG-50 High Accuracy Dynamic Tuned Gyroscope for land strap-down
system
Feature
- High accuracy
- Long service life
- Wide dynamic range
- High reliability
Introduction
A Dynamically Tuned Gyroscope (DTG) is an advanced precision
instrument used for measuring and maintaining orientation and
angular velocity in various applications. Unlike traditional
gyroscopes that rely on spinning masses for stability, a DTG
employs innovative technology that dynamically adapts its resonant
frequency to external forces and vibrations, enhancing accuracy and
performance.
One of the key advantages of a DTG is its exceptional sensitivity
and precision. It can detect even the slightest changes in
orientation or angular velocity, making it suitable for a wide
range of applications, including aerospace, navigation, robotics,
and industrial equipment. DTGs are particularly valuable in
scenarios where high accuracy and resistance to external factors
such as vibrations, shocks, and temperature variations are crucial.
The KTG-50 has been utilized for water surface, land strap-down
systems, fast true-north seeking, television antenna trackers, and
is widely used in spaceflight strap-down inertial systems. The
gyroscope can also be employed for land, sea, aviation, and
space-flight transporters, as well as strap-down platform attitude
systems.

Installation
Products should be installed to ensure that X (Y) axis and the
measurement reference axis coincides, installation error should be
less than 5 '.
Operation
- Only products matching the appropriate power and locked loop
circuit board in order to work properly, need circuit board, please
explain in advance.
- When the product under normal use, you should turn on the power to
start the motor, about 10s, and then the on-lock loop, so that the
products in closed loop state; shutdown, disconnect locked loop so
that the product is in the open-loop operation, and then disconnect
power supply.
- Product energized, shut down in 20s, should avoid shaking the
product, the installation process should be light, light up, the
product non-collision, percussion.
- Product in the use of the process is strictly prohibited to pull
the plug.
- Product in the use of the process, can`t short circuit between
external power supply.
- Abnormality occurs during use, should immediately turn off the
power, fault isolation, if the product internal fault, the customer
shall promptly notify my company, my company organized by the
repair.
