Data Monitoring System
1S663-001
-
The 1S663-001 Data Monitoring System was specifically developed for the Cessna Citation X and serves as the primary diagnostic tool for the aircraft?? electronic Logic Modules. The system is FAA certified for airborne operation. Aft compartment and cabin modules can be tested two at a time while remaining in place. The system is also capable of monitoring the fuel quantity system during flight.

XYZ Bootstrap Directional Gyroscopes
4000H-series
-
Sigma Tek's Directional Gyro with heading synchro output provides a cost effective link to "bootstrap" other instruments requiring heading information for: display orientation to aircraft heading, heading stabilization functions, and other navigational calculations and/or solutions. Specific applications include: Argus Moving Map Display®, L-3 Avionics Stormscope®, and Insight Strike Finder®.

Standard Airspeeds
-
These airspeed indicators have unrestrained movements.These instruments are actuated by ram air and ambient atmospheric pressure obtained from the aircraft pitot and static pressure systems. A moveable pointer and a fixed dial indicate airspeed with the zero index at the 12 o??lock position. Temperature compensation is internal and there is no external zero adjustment. Pointer damping is internally adjustable.

Autopilot Directional Gyroscopes
4000C/D-series
-
The 4000C/D is an air-driven directional gyro with A.C. autopilot pickoffs. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. Two knobs control the gyro. The left knob is used to cage the unit, and the right knob is used to select the instrument’s heading. To change course, the right selector knob is pressed and turned to disengage the dial shaft and set the pointer to a new heading. Releasing the selector knob re-engages the pointer with the dial shaft. As the aircraft turns onto a new course, the pointer returns to its original position. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

True Airspeeds
-
These true speed indicators are differential pressure indicators that measure the difference between static and total pressure produced by ram air from the pitot. The indicated airspeed can be corrected for changes in altitude by turning the knob to align the outside air temperature with the altitude. The moveable airspeed scale will then show the actual, or true, airspeed.

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.

Cageable Attitude Gyroscopes
5000M-series
-
The 5000M is an air-driven gyro that has a pictorial horizon mask and fixed airplane. The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are displayed so that the pilot’s sensing of the gyro indication is the same as the interpretation of the relation between the wings of the aircraft and the natural horizon during visual flight.

Dual Fuel Gauge
1U432-series
-
The 1U432 dual fuel gauge is packaged as a compact, 3” instrument. It has dual D’Arsonval movements that are driven by two resistive bulb transducers in the fuel tanks. The two opposing pointers stand out sharply from the non-reflective black background.
