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.

Accelerometers (aka G-Meters) are used extensively in a wide range of applications including Aviation, Marine, Automotive, Military, and others. They are also used  in inertial navigation and guidance systems in airplane and ship autopilots.They help in a better understanding of static, such as gravity, or dynamic forces due to motion or vibration acting on an object.

Original Mechanical and more recent Digital accelerometers, used on civil and military aircraft, measure the instantaneous acceleration (or G-force) of an aircraft and its occupants compared to Earth's standard gravitational pull, in units of "G" (e.g., 1G, 2G). They enable pilots to monitor flight conditions, maintain safety, or practice aerobatics or combat maneuvers. Made by different manufacturers, they are offered as non-certified instruments, for use on  experimental and homebuilt aircraft, or certified products, installed on civil transport an military aircraft.

Mechanical accelerometers, included in this listing, use traditional components like proof masses, springs, and damping to measure acceleration based on displacement, offering high accuracy and durability for specific applications like flight stabilization and weapons communication. They are often of larger size and more expensive. Digital accelerometers, separately listed, are often Micromachined Micro-electromechanical (MEMS) systems, integrating sensors with microelectronic circuits for smaller size, lower cost, and high precision, making them ideal for flight stabilization, AHARS, and autopilot systems.

The choice of an accelerometer depends on the application's need for accuracy, size, cost, and resistance to harsh environments. 

Please consult the Product Description section and the supplied documentation for more information on different brands of our offered accelerometers.

UNITED INSTRUMENTS 8000/8100 Series Air Speed Indicators (ASI) are FAA TSO'd for installation on certified aircraft. 

The 8000 Series ASI indicate the speed relative to the air at sea level altitude. The 8100 Series True ASI indicate the speed relative to the air at sea level or the desired altitude.The indicator has an inner dial to indicate true airspeed. The altitude and temperature are the conversion factors used to obtain this reading with the use of a setting knob. 

When properly connected to an airspeed tube, the 8000/8100 Series airspeed indicators measure the differential pressure developed between the pitot and static opening. 

The pressure is indicated in units of airspeed mph (M) and/or knots (K).

The FLYdat Engine Management Unit (EMU) has been specially developed by TL ELEKTRONIC for BRP-ROTAX® aircraft engines for storing & indicating engine operating data including Engine Speed, Cylinder Head temperature (CHT), Exhaust Gas Temperature (EGT), Ambient Air Temperature (not on 912 / 914  engines), Cooling Water Temperature of  (only on 582 UL, 618 UL engines), Oil Temperature & Pressure (only on 912 / 914 engines) & hours of operation. It featured  8 sensor input ports, variably occupied according to engine type. In addition, all the input ports were equipped with an alarm, responding when the signalled engine operating value was equal or above the respective stored operating limit. The FLYdat could be used with BRP-ROTAX® 447 UL SCDI, 503 UL DCDI, 582 UL DCDI, 618 UL DCDI, 912/914 DCDI series engines.The engine type, engine number, hour of operation, temperature unit and the respective engine limits could be programmed.

The FLYdat is no longer a listed TL ELEKTRONIC product. It can be replaced by its direct successor, TL ELEKTRONIC Integra TL-6724 Digital EMS, developed in cooperation with BRP-ROTAX®, which forms part of Integra family of Multifunctional Flight Instrument (EFIS) &  Engine Monitoring Systems (EMS) for Light Aircraft. FLYdat units in NEW SURPLUS & USED Conditions, and related parts, may still be supplied depending on existing inventories. Other Aircraft Engine Monitoring Systems (EMS) from different manufacturers (listed separately) are also offered and they could also be considered as alternatives. 

The Integra TL-6724 multifunctional EMS integrates all primary engine instruments (i.e. Tachometer, Manifold Pressure Indicator, EGT, CHT, Oil and Water Temperature Indicator, Fuel Quantity, Fuel Pressure and Fuel Flow Indicator, Voltmeter, Ammeter, Timer, IAT, OAT etc.) and also propeller control for Constant Speed and Choke Control. Designed for use with all light aircraft engines. Its EFIS counterpart, TL-6524, integrates all primary engine instruments and also includes navigation systems (HSI, CDI with connection to the popular Garmin SL-30 and many others) and worldwide 3-D terrain maps. For a total glass cockpit solution, TL-6624 EFIS & EMS Integra integrates all the features of TL-6524 and TL-6724, while TL-6824 Remote Integra Display is also offered displaying all flight and engine data measured by TL-6524, TL-6624 and TL-6724.
