Sensors

AUTOMOTIVE

Sensors play an important role within the automotive industry, providing on-board management systems with essential information.

Cars today require a variety of sensors to monitor elements such as engine speed, tyre pressure, air temperature and more. As being able to respond to changing conditions, by monitoring and responding to data is a must. A standard on board diagnostic interface on most modern-day automotive vehicles will now normally contain more than 50 individual sensors.

This has been largely driven by increased demands on safety, comfort, reliability, energy efficiency and reducing environmental impact. All key areas that are becoming more important in modern day cars, as more demanding requirements are placed upon the machines. As a result sensor technology has become an integral part of automotive vehicle design and manufacturing. We are committed to improving the safety of vehicles and helping to make them more energy efficient and environmentally friendly.

Quest’s automotive sensors are produced to exacting specifications, providing essential data used within a number of automotive vehicles. Allowing on-board systems to identify and respond to changing conditions both inside and out.

We also provide sensors to the automotive sector. These are regularly designed and manufactured to exacting specifications, often on a custom basis. As we have the experience and capacity to optimize and adapt sensors to meet individual requirements and markets.

Common Automotive Sensors
Some common sensors that can be found in most automotive vehicles.
  1. Fuel tank pressure sensors that monitor evaporative emissions and detect leaks.
  2. Gas sensors which ensure that only clean air can permeate the passenger compartment.
  3. ASICs that control speed dependent windscreen wiper rates and window lift controls.
  4. Electrochromic rear-view mirror dimming chips which make night time driving less stressful.
  5. Strain gauges that inform air bag deployment and ensure seat belts get fastened securely.
  6. Speed sensors used in Anti-lock Brake Systems (ABS) that monitor the wheel speed, helping to prevent wheels from locking up.
  7. Intake air temperature sensors monitor the temperature of the air entering the engine and help to regulate the air/fuel ratio.
  8. Position sensors are used to monitor the rotational speed of the crankshaft to control the fuel mixture and spark advance.
  9. Mass air flow (MAF) sensors are used to monitor the density and volume of air that enters the engine.

INDUSTRIAL

Industrial sensors are an essential component of modern manufacturing and production processes.

These devices are designed to detect and measure various physical parameters, such as temperature, pressure, and humidity, and provide real-time data to control systems and operators.

One of the primary benefits of industrial sensors is their ability to improve efficiency and productivity in manufacturing processes.

By providing accurate and timely data, sensors can help operators optimise production and reduce waste, leading to cost savings and increased profitability.

Sensors can also help improve product quality and safety by detecting and preventing defects or anomalies in the production process.

MEDICAL

The potential for MEMs based sensors to revolutionise the Health Tech and Well-Being market sectors has long been recognised and is rapidly gaining pace.

Of course regulatory compliance in this sector is of paramount importance but does represent a degree of inertia to be overcome before new ideas can be implemented.

Quests ASICs are used in heart pacemakers and our precision analogue foundry ICs in MRI and CT scanners. Quests foundry thermopile sensor chips are in widespread use in non contact ear thermometers. Quests photodiode manufacturing capabilities are exploited in urine analysis equipment where colouration of chemical strips are measured.

Most recently, production of blood viscosity sensors has started for personal INR monitoring systems for people at risk of stroke or heart problems.

Lab on a chip for blood analysis and nano wires with electro-polymerised, antigen selective coatings are current areas of R&D interest together with our commercial partners in industry and academia.

Quest is helping to make people healthy and live longer.

DEFENSE

Sensors in the Defense and Security Industry

Our sensors feature in defense and security devices across the globe

With defense and  security devices  becoming more advanced these products are using sensors to help to offer more capabilities.
Our sensors are used in Intelligence, Surveillance and Reconnaissance and the delivery of physical effects (electronic warfare, countermeasures, directed energy and weapons) have been and are being developed by Quest’s advanced design team.
This division focuses on:
  • Electronic warfare sensors
  • Surveillance system sensors
  • Weapons systems technology sensors
  • Undersea early warning sensors
  • Advanced propulsion and weapons effects such as drone fin sensors
Quest contributes to the security industry in many ways, producing sensors for a range of different products and devices from alarm systems to CCTV cameras.
Our custom ASICs feature in many different devices within the security industry, including;
  • security and alarm systems
  • security surveillance systems
We produced ASICs for the addressable protocols that monitor alarm systems in public buildings such as Hong Kong Airport and the twin Petronas Towers.
Our silicon chips are used within radiation detectors used by Homeland Security, nuclear power stations and passive infra-red motion detectors.
