Hydraulics
Hydraulics are the life blood of any airframe,
providing primary flight controls, as well as
controls for safe landing combining braking
and thrust reverse. Our sensors monitor
the hydraulic lines making sure they are
working effectively and safely.
Challenges
The Hydraulic systems operate in extreme
conditions, at altitudes generally up to 41,000 ft andtemperatures of -70 degrees fahrenheit. Therefore
reliable sub-systems and components are of criticalimportance. Within this application we understandthat qualifications can be arduous and therefore it isimportant to understand the requirements in detail.
Failures in this application can cause aircraft on
ground (AOG) conditions, which are hugely costly toairlines and overall air framer credibility. If a sensor
fails, we understand that in-service removals are
extremely costly and logistically challenging to theairline. This is why reliability is our number one priority
when it comes to providing flight-qualified sensors.

Solutions
We offer robust solutions, with field data supporting
MTBUR of up to 1.2 million operating hours. We provide
confidence to our customers that their assets will
operate reliably over the design life and beyond.
Our sensors are designed to meet the latest stringent
EMC / Lightning protection requirements driven byadoption of composite aircraft. We provide bespoke
solutions dependent on the needs of the customer,
including redundancy and integrated temperature
measurement as examples. Our brand is widely
recognized as the world’s leading supplier within
this application due to our longevity and technicalexpertise in this field.

ECS
The Environmental Control System (ECS) provides clean
air, thermal control and cabin pressure for the crew andpassengers. Our sensors ensure that these systems operate
efficiently and reliably, which ensure that passengers areable to fly safely and in comfort.

8

Challenges

Solutions

The ECS is an essential system within the airframe,
providing cabin and emergency air supply, fire
protection and anti-icing system. Therefore productreliability is paramount, especially in the sensor, which
is providing the information to the control system.
Often these sensors will be fitted for the whole life of
the aircraft, so performance over the aircraft’s lifetime
is crucially important. Failures within this application
can cause AOG conditions, which result in rising costs
for airlines and a loss of overall airframe credibility.
In service removals of failed sensors are particularly
costly and challenging from a logistical perspective,
thus affirming the importance of product reliability a characteristic that our products embody fromdesign through to qualification.

We provide accurate sensors for complex low
pressure differential pressure (ΔP) applications, aswell as a vast experience designing sensors to provide
a robust solution at a competitive price. Our sensors
within this application are used on all of the world’s
most produced aircraft.

Fuel
Fuel level and rate of consumption are vital
parameters for the pilot, to assess whether
there are any deviations to the calculated
consumption rate or indeed whether
unexpected flight path changes can beaccommodated. Additionally, in-flightmonitoring of the fuel inert gas is measured
to ensure the On-Board Inert Gas Generating
System (OBIGGS) is operating correctly, thus
providing robust safety checks for the pilot.
Challenges
Reliability is everything when it comes to fuel systems.
The accurate ΔP measurement, which combinedwith flow, enables fuel metering and specific fuelconsumption to be calculated. The data provided has
to be reliable and accurate due to the critical natureof how this information is being used. Also on anotherfuel application, where the inert gas level is monitored
to ensure there is no risk of ignition, a complex O2 andpressure sensor is required to provide confidence thatthe system is operating correctly.

Solutions
We are constantly challenging ourselves to reduce our
production costs whilst providing world class quality
sensors, because we understand that having a costcompetitive solution is essential to the success of ourown business and those of our customers. We havequalified our combined pressure and O2 sensor tothe most arduous EMC specification, providing ourcustomers with a market leading product. We have oursensors installed on the world’s most produced twin
aisle aircraft.

APU
The Auxiliary Power Unit (APU) provides essential functionality
to the aircraft, providing, electrical power, pneumatic or
hydraulic to start the engines, whilst also providing lighting,air conditioning and water pressure to the main cabin crew
and passengers, when grounded. It also plays a critical rolein the event of an engine failure, by providing the power torestart the engine(s) during flight. The Druck pressure sensors
measure the critical parameters to ensure these systems
operate safely and efficiently, whilst also ensuring ground
filtration checks can be completed to allow take off.

12

Challenges

Solutions

The APU needs to operate reliably when called upon,even in extreme temperature conditions. This could
be when the aircraft is being boarded, in locations
that regularly reach temperatures > 40 degrees
celsius or indeed at extreme cold temperatures, as
low as -56.5 degrees celsius, when in an unlikely
event such as an engine failure has occurred andpower is required to re-start the engine. These harshenvironments, which cannot support human life, needto operate to sustain life when called upon.

Our team offer many years of experience,
ensuring that products undergo a robust
qualification testing program. We have field provenreliability data from products in service today on
the world’s most produced commercial airframes.
We have supplied products of varying complexity,
which included a triple sensor configuration, offering
redundancy during operation, in turn providing a costeffective and reliable solution to our customer.

Additionally, accurate pressure sensors are necessary
at low pressures to ensure that filters are not blocked
prior to take off, which would result in an AOG event,resulting in high costs and unplanned removals.

EngineAircraft engines are extensively tested
to prove reliability. Certification testing is
extremely challenging and lengthy, due tothe absolute reliance on this complex system
to provide power to enable and to sustain
flight. To provide this level of reliability all
systems and components used within theengine need to be equally robust.

Our sensors allow the engine to operate,
through reliable measurement of the fueland oil pressure. Our sensors monitor
the engine health, providing prognostic
information and also critical engine control
data to the pilot.

Challenges

Solutions

The engine environment is arguably the most hostile
within the aircraft due to the extreme temperatures,
rapidly changing environmental conditions andexposure to the elements. The demands for continued,
reliable data from the products controlling the engine
parameters is a given. Fulfilling these needs isextremely challenging as the function of the sensor
ensures the engines operate safely and efficiently.
Being exposed to the elements at 41,000 feet at
temperatures close to = 70 degrees fahrenheit
requires a robust design, qualification process
and high quality manufacturing facility.

Our pressure measuring solutions have field provenreliability data, as well as having qualified products for
installation on the world’s most produced commercial
engines. We have partnered with OEM’s to design
bespoke solutions such as providing high burst
pressure, whilst maintaining high accuracy demands
and helped overcome pump ripple challenges. We
have gained the trust of our customers throughour rigorous and robust qualification process. Thisapplication has been a significant area of focus overthe past decade, where we have gained a tremendous
amount of knowledge.

ADC/ADM
Air Data Pressure Measurement from Pitot
and Static ports provides critical information
to the Integrated Air Data Inertial Reference
System (ADIRS) to enable the Captainand Flight Officer to understand key flightinformation such as Air Speed and Altitude,
which is then computed and displayed on
the Primary Flight Display.
Challenges
This application provides flight critical information
for the safe navigation and control of the aircraft,therefore product reliability and long term
performance is of great importance. Accuracy overthe life of the product, combined with the ability toconsistently operate within harsh environments are
extremely challenging.

Solutions
Our team has developed, over a 10 year period,a unique MEMS pressure sensor that provides
unprecedented levels of performance to meet thedemands for this application. The MEMS device
contains TERPS technology, which negates the effectsof long‑term stability concerns associated withtraditional piezo resistive technologies. This technology
has been subjected to harsh qualification testing toensure it is ready to serve this market.
