Product
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.

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®.

Breakout Box and Data Logger
1U643-001
-
The 1U634 Breakout Box and Data Logger was developed for the Cessna Excel to serve as the main diagnostics tool for the aircraft?? electronic modules. It allows access to the module pins, and its internal microcomputer digitizes the signals and transmits them to a PC-compatible computer. Advanced software in the computer displays pin voltages either in numerical or graphical form. Data files can be recorded on disk, and played back at a later time for detailed analysis.

4000B ARINC-style Directional Gyroscopes
-
This instrument was developed for those pilots that prefer the distinct, professional look of an ARINC-styled cockpit. It is identical to the standard 4000B model differing mainly in aesthetics. Besides its distinct bezel and airplane, the display graphics and colors differentiate it from the standard model. A heading reminder bug is available as an option.

Restrained Airspeeds
-
These airspeed indicators have restrained 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’clock 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).

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.

Autopilot Attitude Gyroscopes
5000E/L-series
-
The 5000E air-driven attitude gyro is another variation of our standard 5000B model. It includes inductive pickoffs that generate the signals necessaryto drive an autopilot. The intuitive display has a moving horizon mask that indicates the position of the aircraft’s wings in relation to the natural horizon. This attitude information is passed along to the autopilot system.

Product
Multifunction Engine Gauge
1U417-series
-
The three essential engine parameters are packaged in a 3” instrument. The 1U417 was derived from the Garwin 22-804 and is a direct replacement. As evidenced by its predecessor, the three most essential engine parameters have traditionally been the most requested by our customers.
