Typically, a pyroelectric sensor, composed of pyroelectric film and circuitry in a housing filled with dry air or nitrogen, is used for clinical thermometry. Infrared radiation changes the temperature of a thin foil of pyroelectrical material, such as polyvinylidene fluoride.
In addition to thermopiles, we offer pyroelectric sensors, infrared light sources and Pirani vacuum sensors. Thermopile Based Products. Thermopile sensors operate by generating a small thermoelectric voltage proportional to the detected radiation. They can be used to determine surface temperatures or to measure the concentration of certain gases, like CO2, CO, N2O, hydrocarbons or anesthetics ...
Pyroelectric crystals have a rare asymmetry due to their single polar axis. This causes their polarisation to change with temperature. This so-called pyroelectric effect is used in sensor technology. For this, a thin pyroelectric crystal is coated perpendicular to the polar axis with electrodes. On the upper electrode of the crystal, an absorbing layer (black layer) is applied. When this layer ...
Pyroelectric IR sensor. Compares to the five senses of human, infrared sensor is the role of “eye”. Material called ferroelectrics absorbs thermal energy that changes spontaneous polarization generating a surface electrical charge. The charge is proportional to polarization change. This phenomenon is called the pyroelectric effect.
Sensors. KEMET offers a growing portfolio of sensors that detect infrared thermal energy and vibration. Our pyroelectric sensor recognizes changes in the pyroelectric spectrum within its viewing proximity. KEMET vibration sensors are sensitive enough to monitor and predict failures in industrial equipment before it can become a major issue.
Pyroelectric detectors are thermal detectors: Temperature fluctuations produce a charge change on the surface of pyroelectric crystals, which produces a corresponding electrical signal. This temperature gradient can be created by the absorption of light.
Pyroelectric sensors for measuring repetitively pulsed energy at up to 25 kHz. These sensors use a pyroelectric crystal that generates an electric charge proportional to the heat absorbed. The response time of the pyroelectric sensor depends on the time it takes for the heat to enter the crystal and heat it up. For metallic type pyro detectors, this time is tens of μs and thus the metallic ...
· Pyroelectric sensors are not suited for CW measurements, as they convert energy from light pulses into voltage pulses. A black broadband or ceramic coating is used for low or high power measurements, respectively. Large sensor areas from Ø11 mm to Ø45 mm allow easy alignment. The energy sensors features BNC connectors for use with an oscilloscope, as well as standard power …
· Pyroelectric sensors help to ensure that automated electronic devices work properly. Thus, these devices can be relied on because they are safe to use. Sensors that take Advantage of Pyroelectric Effect Motion Sensors. Infrared motion sensors are either passive or active. Active infrared sensors such as garage door security sensors work over a longer distance because the sensor and …
The Pyroelectric Infrared sensor is made of a crystalline material that responds to the change of incident thermal radiation and develops a related electrical signal when a heat source (human body) crosses over the sensor FOV. This type of sensor responds to the variation of infrared radiation rather than the infrared radiation itself.

Pyroelectric sensors comprise of a material which is not only highly sensitive to thermal changes but will also pick up mechanical and electro-magnetic distortions. The latter can be very frustrating since in many cases, it arises only in the last stage of product design and may require major changes. This webinar will provide effective strategies for coping with difficulties that may be ...

Pyroelectric detectors are sensors for light which are based on the pyroelectric effect. They are widely used for detecting laser pulses (rather than continuous-wave light), often in the infrared spectral region, and with the potential for a very broad spectral response. Pyroelectric detectors are used as the central parts of many optical energy meters, and are typically operated at room ...
