AC Calibration Standard
1U647-001
The 1U647-001 is a low cost calibration standard used to determine if a 1U632-100 or a 1U663-100 DMU requires factory calibration. Its portability makes it ideal for field-testing. The standard generates signals that simulate the aircraft’s resolvers, rotary variable transformers (RVTs), and linear variable displacement transformers (LVDTs). The unit also generates a pulse width modulated (PWM) signal, and routes the output of an ARINC 429 source to the different DMU input channels. The calibration standard connects directly to the DMU and replaces the output signals of an active extender card. Discrete switch settings simplify testing. The unit is housed in a rugged aluminum case.

Multifunction Engine Gauge
1U378-series
This 3” instrument combines the three essential engine parameters in a compact package. Rugged D’Arsonval meter movements with two jewels are used to indicate cylinder head and oil temperatures. A brass bourdon tube mechanism precisely indicates oil pressure. A selection of fittings is available to simplify installation.

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.

Customized Indicator Cluster Gauge Kits
169CL-series
Over the past 40 years, Sigma Tek has custom designed and manufactured reliable, proven instruments for virtually every type of aircraft that flies. This includes precision modular instrumentation configured to customer's exact specifications. Cluster modules measure 1.44" square, and can be arranged in almost any combination for optimum panel utilization. Individual modules are easily removed for calibration and service.

Standard Attitude Gyroscopes
5000B-series
The 5000B 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.

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.

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.

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.

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.

ARINC-style Attitude Gyroscopes
1U367-series
The 1U367 has a pictorial horizon mask and a fixed airplane. The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are diaplayed so that the pilot's sensing of the gyro's horizon indication is the same as the interpretation of the relationship between the wings of the aircraft and the natural horizon during visual flight.

Standard Directional Gyroscopes
4000B-series
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. 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).
