Customised sensors integrate control electronics

MCE is developing a capability for the integration of drive and control electronics in specialised sensor applications such as pressure and flow measurement and accelerometers.

Micro Circuit Engineering (MCE) of Tewkesbury, UK, is developing a capability for the integration of drive and control electronics in specialised sensor applications such as pressure and flow measurement and accelerometers.

The service is intended to meet the requirement for sensors and measurement devices that cannot be satisfied through the purchase of off-the-shelf components.

It will permit system designers to provide enhanced performance through: locating the drive, measurement and control circuitry close to the sensing element; maximising the scope for miniaturisation; allowing the sensor to be used in remote or difficult-to-access locations; and enhancing sensor performance by the use of purpose-designed device packaging.

This type of custom approach using bare sensors can provide a sensor system that meets performance, dimensional, communication and environmental specifications that cannot easily be achieved with off-the-shelf components.

MCE has gained considerable experience in developing custom solutions for sensor systems.

Its capabilities include design and production of mixed signal ASICs.

These can incorporate the analogue signal and digital processing circuitry on one piece of silicon to condition the analogue signal from the sensor and provide analogue-to-digital conversion close to the bare sensor.

MCE is also experienced in integration of the sensors, the drive and the control circuitry within a miniaturised package.

Customised packaging and assembly extends the capabilities of the sensor system to permit operation at high temperatures, high or low pressures, or other special requirements.

Remote data transmission can be included, using telemetric devices with power provided by radio frequency induction.
