Electric Attitude Gyroscopes
5000EG-series
The 5000EG gyro is based on our air-driven 5000B model, whose proven reliability has made it the industry standard for many years. There are two models available: 14 and 28 VDC. The rotor is precisely machined from a heavy-metal tungsten alloy, which has a higher mass than brass, contributing to the instrument’s demonstrated stability. The electric motor is driven by a built-in power inverter, and has an integrated air-erection mechanism. A warning flag is deployed upon loss of primary power. During acrobatic flights or short stops, the gyro’s mechanism can be caged whenever the knob is pulled.

Integrated Multi-Gas Detector for Unmanned Aerial System
MUVE C360
The FLIR MUVE™C360 is a multi-gas detector completely integrated with an unmanned aerial system (UAS) to provide real-time continuous monitoring of chemical hazards while on the move. The sensor block boasts 8-channels, which includes a photoionization detector (PID), Lower Explosive Limit (LEL) detector, and six other sensors. The integrated snorkel is designed to negate the effects of rotor wash, extending past the propellers to sample the unperturbed air. The MUVE C360 sensor block quickly latches to a proprietary integration dock mounted to the UAS. The FLIR calibration station features the same dock, so the operator can easily connect for routine sensor verification. Sensor readouts are prioritized based on alarm conditions and are displayed real-time on the pilot’s interface in the FLIR VueLink™ app. The MUVE C360 is a time-saving, game-changer for emergency responders, industrial safety officers, and environmental monitoring experts.

Motor Test for Electric Scooters
*The performance data of electric motors, in the majority of all cases, is performed by a brake test. Power input is calculated from current and voltage. Torque and power output are measured with a brake. It is important to reach, for each point, a persistent temperature. In case of large outer rotor BLDC motors, which are usually used for electric scooters, this traditional procedure may take many hours to complete, and is very complicated. *For several years, an innovative motor tester of MEA Testing Systems Ltd. is on the market. This testing system avoids any temperature confusion by testing a motor at constant temperature over the entire speed range. The test procedure is very fast, and gives the full load performances, including PWM current, voltage, torque, and driver efficiency, from stall up to no load. *During the test procedure, the motor is freely accelerated from stall to no load speed. The load of the motor is only the predetermined inertia of the rotor. From the moment of inertia and the acceleration, the torque of the motor is calculated and, also, the power output over the whole speed is given. Since the entire measuring time, depending on the motor size, is usually less than one second, the motor has no time to warm up. It remains at room temperature.

Flow Indicators
Flow indicator with rotor features a self-cleaning mechanism to ensure full visibility of the rotor at all times. Typical sight flow indicators suffer from poor indicator visibility through normal use from build-up that impedes observation of the rotor through the viewing window. Typically, for a sight flow indicator to be cleaned, it must be removed from the pipeline, cleaned and then replaced at some specified time, such as during plant shutdown. Unfortunately, dirt build-up does not typically schedule itself to correspond with planned shutdowns. Enter the KOBOLD DAA Series flow indicator. Simply twist the sight glass and the integral wipers clean the flow indicator's viewing area to allow unobstructed observation of the rotor. The offending contaminants are then simply washed away by the media flow. This process may be repeated as often as desired with no fuss and no downtime. The DAA is available with brass or stainless steel fittings with " to 1" NPT female threads. The DAA is also available without a rotor for observation of fluid condition.

Turbine Flow Meters
Axial turbine flow meters are designed with wear resistant internal components to provide trouble-free operation and a long service life. Fluid entering the flow meter is first conditioned by the inlet flow straightener which reduces turbulence in the fluid. The moving fluid causes the rotor to spin at a speed that is proportional to its flow rate. As the turbine blades on the rotor pass through the magnetic field of the pickup, an electronic pulse is generated.

Crowbar Resistors
Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.
