UMA airspeed indicators are fully FAA TSO'd to C2d specifications for installation on certified aircraft. Installable in a fixed wing aircraft with a reciprocating or turboprop engine. Must be installed in a temperature controlled environment form -55 to 85°C, to a max altitude of 25,000 ft. These airspeed indicators are available in different versions, 2-1/4",Single Speed MPH and 3-1/8" single or dual scale (MPH/Knots) versions with an outside/Inside scale: 40-200 MPH/40-170 Knots, housed in a Valox 420 Plastic case and weighting 8.6 oz. They are offered with or without certification. ASI markings are sold separately for each unit at additional cost. Please select the markings option if markings are required. 

UMA NON TSO'd mechanical manifold pressure gauges (MPGs) are offered in two series, the conventional 2-1/4" manifold lightweight  gauges with a slim design and a single diaphragm and the newer 3-1/8" and 2-1/4" gauges which incorporate a dual diaphragm design improving the longevity and reliability of the instrument. Standard markings are black and white while optional color markings can be ordered. Cases are from cast aluminum or Valox 420 plastic depending on model selected.

1-1/4 inch TSO'd Electronic Fuel Pressure Gauges from UMA INSTRUMENTS. Black & White dial marking. Available in different pressure (PSI) ranges. Case: Aluminum. Weight: 4.0 oz. UMA sensors are sold separately.

TSO'd Electronic Fuel Quantity gauges from UMA INSTRUMENTS (indicated by the letter "T" in the PN) are offered in 1-1/4 in. and 2-1/4 in. sizes for installation in respective panel hole diameters and mounted with (4) 6-32 screws. Smaller 1-1/4 in. instruments can be cluster mounted as close as 11/2” centers utilizing panel space without compromising readability. They can be powered from 14 or 28 volts. Signals are acquired from remote mounted sensors, processed and displayed on black analog dials with white easy to read markings indicating empty to full fuel level. Each gauge uses rugged aircore meter movement for vibration resistance and repeatability. Available in different versions based on their sender type and range. UMA sensors are sold separately.

This 2-1/4 inch flap indicator uses a resistance potentiometer as a flap position sensor. Transmitter is required. Wt: 9.8 oz.

UMA line of precision electronic pressure senders feature precision, solid state sensors and circuitry to give unequalled performance and are designed for rugged use in just about any environment.  They are offered in TSO'd and Non TSO'd models and gauge, differential and absolute types. UMA TSO'd electronic pressure senders are the most economical TSO’d units on the market. They are compatible with avgas, jet fuel, engine oil and many other fluids. Because they have internal voltage regulation, they are compatible with indicating instruments that do not have precision output voltages. Units for fuel and oil pressure are certified under TSO C47. Units for manifold pressure are under TSO C45a. For additional information please refer to the attached documentation.

UMA  2-1/4" electric tachometers with their high resolution and easy to read displays were designed to offer aviation styling and performance for all types of aircraft. The analog model has a 270° sweep which provides great resolution in both the 3500 and 7000 ranges. The digital model has a bright LED display. Separate power source required. Installation is simple and instructions are included. They can replace mechanical tachometers in Lycoming/Continental engines.

Current: 80 milliamps ­ Size: 2.25" round x 2.75"deep.

UMA NON TSO'd Electronic Amp Meter Gauges (Ammeters) are available in different series for different measurement ranges and installation in different panel hole diameters. 1-1/4" series allow utilization of panel space without compromising readability. They can be powered from 14 or 28 volts. Signals are acquired from remote mounted sensors, processed and displayed on analog dials with easy to read markings. Each gauge uses rugged aircore meter movement for vibration resistance and repeatability. Each gauge can be placed in a 1-1/4” diameter hole and mounted behind the panel with (4) 6-32 screws. They can be cluster mounted as close as 11/2” centers. Also available as new manufacture electric with 2-1/4" dia. Other UMA series of electronic ammeters include 2-1/4" series with moving coil and 85° Sweep and 2-1/4" Dual Amp/ 0-30 volt meters with moving coil  and 85° sweep.

NOTES:

These ammeters come with the suitable shunt. Different shunts are used depending on ammeter part number.

All Part Numbers beginning with the letter "T" are TSO'd for Certified Aircraft.

These UMA new manufacture NON TSO'd electric ammeters offer accuracy, rugged construction, and contemporary styling. They are available in different  measurement ranges with a 270° sweep and are suitable for installation in 2-1/4" panel hole diameters. Made in U. S. A. and furnished with shunt.

UMA Electronic Hydraulic Pressure Gauges are offered in TSO'd and Non TSO'd models and 1-1/4"  or 2-1/4" diameters to fit respective aircraft panel openings. They are housed in aluminium or Valox 420 plastic cases (depending on the model) and connect to  precision, high pressure transducers which mount directly to the aircraft's hydraulic system. Standard markings are black and white. Recommended for new design projects and applications. 

Note: Pressure Transducers (Senders) ARE NOT INCLUDED in the prices of the pressure gauges. They are sold separately and are not TSO'd.

UMA Non TSO'd airspeed indicators are offered in 2-1/4" and 3-1/8" Single (MPH) and Dual Range (MPH/Knots) versions for installation on experimental aircraft only.
