Food, General IR Spectroscopy & Oil Monitoring Sensors
QDA Pyroelectric Infrared Food, General IR
Spectroscopy & Oil Monitoring Sensors, Array
Overview
KEMETs QDA line sensor arrays, or linear arrays, utilize
unique thin-film pyroelectric PZT material to offer
outstanding resolution and performance across a wide
infrared wavelength range.
The ASIC readout electronics output is a multiplexed,
amplified and filtered analogue signal for each sensor
element. The sensor is housed in a low profile sealed metal
package along with a temperature sensor, and can be fitted
within a choice of filter windows.
An additional “+1” sensor element can provide higher
sensitivity on a discrete wavelength, typically for lubrication
oil or foodstuffs. This +1 sensor is located for ATR and
transmission use.
Applications
General IR spectroscopy (portable, robust spectral
engines)
Lubricating oil and fuel monitoring (quality, wear,
adulteration)
• Foodstuffs (constitution, adulteration, milk tampering,
decay)
Industrial process and safety
Process monitoring (wind turbine, petrochemical,
pharmaceutical)
• Engine condition monitoring
Temperature measurement (non-contact line scanning
measurement)
Flame, material, gas and gas flues analysis
• HVAC and refrigerants
Home and building technology
• Environmental and pollution monitoring
• Laser calibration
• Imaging (line scanning)
• Medical capnography
Markers in blood and body fluids

The product(s) above contains a substance by more than 0.1wt% per product weight that was published in the 8th update of
the REACH SVHC substances (December 19, 2012).
3. Regarding the safety of the food sensors (Piezoceramic products):
The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as the main ingredient. It
is chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please
note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.
4. Technical product information on the food sensors (Piezoceramic products):
The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide (PZT)
has been established, and there is no alternative material that can exhibit superior performance than PZT at this moment.
Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) AnnexIII (7c.1).
5. The responsibility of piezoceramic manufacturers:
Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the
article 33 of the REACH regulation.

Clock Diagram
510 Element Line Sensor Array
The 510 channel line sensor contains two multiplexed analogue outputs, each one providing data from 255 channels. The
first output (pin 9) provides data from all the even numbered pixels, counting upwards from 2 to 510. The second output
(pin 11) provides data from all the odd numbered pixels, starting at pixel 509 and counting downwards to pixel 1. The clock
diagram below shows which pixel numbers are available from each output as the device is clocked.
Pixel 1 is the nearest pin 1 of the device.

QDA Pyroelectric Infrared Food, General IR Spectroscopy & Oil Monitoring Sensors, Array
Circuit Diagram
The amplification circuit consists of low-noise preamplifiers for each individual sensor elements, analogue switches and
an output amplifier. The pre-amplifiers transform the signal charges measured at each sensor element into a conditioned
voltage. The amplified signal is then passed to sample and hold, multiplexer output buffer for the read-out process. The
digital inputs are CMOS compatible. A 10k NTC thermistor is integrated within the package to monitor the line
sensor temperature.

Handling Precautions
Pyroelectric Infrared Sensors should be kept away from indirect and direct sunlight, the headlights of cars, wind, and
exposure to strong vibration and strong shock.
Do not use in water, alcohol ETA, corrosive gas or under sea breeze.
Do not be expose to corrosive substances.
Do not drop or apply any mechanical stress.
The performance of this device can be affected by ESD. Precautions should be used when handling and installing the
sensor. Precision devices such as this sensor can be damaged or caused not to meet published specification due to ESD.
Please note that there is limited ESD protection built-in as the device is optimised for low power consumption and low noise
operation. Human Body Model (HBM), per JS-001: 2,000 V.
Pyroelectric Infrared Sensors should be stored in normal working environments.
Solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long-term
storage.
KEMET recommends that ambient storage conditions are < 30°C and < 60% relative humidity and that maximum storage
temperature does not exceed 110°C. Atmospheres should be free of chlorine and sulfur-bearing compounds.
Temperature fluctuations should be minimized to avoid condensation on the parts.
For optimized solderability sensors stock should be used promptly, preferably within 24 months of receipt.
