Corporate Background

VARTEK Corporation custom designs and builds precision laboratory and ground support test equipment, such as excitation power sources and monitoring equipment. This equipment is used in the performance testing of gyroscopes, accelerometers and inertial navigation systems, both gimbal and strapdown.

VARTEK is proud to bring over 35 years of experience in test equipment development and manufacturing to every customer requirement. Throughout this time, Vartek has satisfied customer requirements by designing solutions to meet their specialized needs. Unique circuitry for gyro and accelerometer excitation, suspension and test measurement have been designed, such as:

START/RUN LINEAR RAMP DECAY: Provides for setting of the unit under test (UUT) Start voltage amplitude, duration and decay time to the voltage Run level. One of the observed effects has been reduced running power at a consistently repeatable level.

ANTI-HUNT: UUT Gyro motor hunt is actively minimized to enable precise monitoring of motor bearing performance with a differential wattmeter.

DYNAMIC RUN DOWN ANALYSIS: Sequentially removes the voltage input and sense leads from the UUT, preventing the wheel power source from effecting the back EMF of the motor while it is being monitored during a Dynamic Run Down (DRA) test.

PHASE ADVANCE: Controls the wheel power source output phases in a direction opposite to the direction of the UUT motor slip.

PHASE LOCK: Synchronizes multiple power supplies.

Design Approach

VARTEK's equipment is typically designed to precise customer specifications. Standard design modules are used to the greatest extent possible to provide rapid response in meeting those requirements. Manufacturing from standard modules ensures excellence in workmanship and flexibility in response. New modules are implemented with intelligent design using proven technology. Vartek's architectural simplicity supports ease of maintenance through module swapping. Intrinsic software is provided as needed to meet and support the operating functionality or communications required for customer's applications. Our goal is to deliver reliable equipment supported with clear, strong documentation.

Maintenance and Refurbishment Services

VARTEK also maintains and refurbishes existing precision test equipment for the inertial navigation industry including laboratory or ground support test equipment such as excitation supplies and monitoring instruments. In many instances we have updated older field equipment with state of the art technology. Please contact us when you have any questions about refurbishment needs.

Warranty

All equipment sold by VARTEK Corporation has a conditional limited warranty for a period of two (2) years for labor and materials. VARTEK expressly warrants that new units, new parts and overhauls (which shall mean complete recondition and furnishing new parts at VARTEK's discretion) made or sold by VARTEK will conform to agreed specifications, drawings and samples, and will be free from defects in material or workmanship for a period of two (2) years from date of shipment.
