The PSP-CCD is a 2-megapixel CCD camera used for pressure and temperature sensitive paint data acquisition. The camera is small and lightweight allowing for an array of cameras to be mounted in small areas. Communication with the PSP-CCD is via Gigabit Ethernet. The camera comes in two options, one a color sensor and one a monochrome sensor. The color camera is used in Binary PSP and particle shadow velocimetry applications whereas the monochrome version is used in monochrome PSP or surface stress sensitive film applications. 1.9 megapixel CCD sensor GigE Connectivity 8- or 12-bit output format External TTL input and strobe output Easy to use software interface tailored to PSP and TSP Lens control available via ProAcquire software and LC-2 controller (sold separately) Sensor Resolution 1600 x 1200 (1.9 megapixel) Type KAI-2020 CCD Format 11.89 mm (H) x 8.94 mm (V), 14.8 mm diagonal (1” optical format) Pixel Size 7.4 μm Frame Rate 35 fps (40 MHz) Standard clock 44 fps (50 MHz) Overclocked Electron Full Well Capacity 20,000 e− Readout Noise 20 electrons Dynamic Range 60dB Output Format(s) 8, 12 Binning H/L 1x, 2x, 3x, 4x, 8x Maximum Exposure 10 seconds Minimum Exposure 50 μs Shutter Global Trigger Inputs External (TTL via IN1/IN2), software, computer Options Level, edge, pulse width, internal exposure Modes Free-run, standard, double, frame accumulation Strobe Output Programmable position and duration Communication Interface GigE On Board Memory None Software Interface ProAcquire Lens Control Available in ProAcquire (LC-2 integration) Environmental Vibration/Shock DIN EN 60068-2-64 Operating Temperature Range 0˚C to 50˚C Humidity 20% to 80% non-condensing Size & Weight Size 98.5 mm (L) x 29 mm (H), 44 mm (L) Weight 220 grams Lens Mount c-mount Power Requirements External Power Input 12-24 VDC Power Consumption 4.9 W @ 12 VDC Export ECCN EAR99
The educational PSP/TSP system provides everything needed for new users to get started using PSP and TSP. This system provides high spatial resolution, excellent dynamic range, but lower data capture rates than our higher-end systems. For applications where time in the wind tunnel is not a critical issue, it represents an excellent cost/performance trade-off. This system provides full capability for undergraduate demonstrations, training, and laboratory exercises. It will support all but the most demanding graduate and faculty research programs requiring distributed pressure and temperature measurements in wind tunnel environments. The system employs proven ISSI LED technology for excitation of the luminous probes in the paints. The camera is based on a color CCD sensor, eliminating the need for a filter wheel when using bi-luminophore paints. The OMS-Lite software package is easy to use and fully supports the educational and research capabilities of the PSP/TSP system. Standard System Components: - Color CCD Camera: 12 bit, 1.9 Megapixel color CCD camera with Gigabit Ethernet connectivity - LM2X-DM-400 LED Array: High-power UV LED module with TTL control - PSG-3: Pulse/delay generator for instrument control and synchronization - Parbolic Reflector and Diffuser: Focuses output of LM2 series LEDs from 120- to 40-degrees giving 2-3 times increased focused output. - PSP/TSP Starter Kit: PSP starter kit including beginner paints in spray cans, Binary FIB and FIB Basecoat with HVLP paint gun and airbrush with compressor and fittings. - Optical Kit: This kit contains all lenses and filters needed to get started using PSP and TSP. Available with c-mount or Canon® EF mount lenses. - ProAcquire and OMS-Lite: Data acquisition and data reduction software. Test models used in the lab experiments are provided with the the educational PSP/TSP system. An aluminum delta wing and NACA 0012 airfoil model are included with the system along with the mounting hardware to install them for either 1/4″-20 or M6. Other models are available to purchase upon request as well as pressure tapped models. The PSP system package has several options for purchase. Depending on the size of the facility the system will be used in, some different optical kits may be appropriate. Additional LEDs and cameras can also be added to systems and seamlessly integrated. Building a system with the appropriate hardware for your facility is paramount to the success of the results.

Temperature Sensitive Paint is an optical sensor for temperature measurements. A paint-like coating is applied to a surface and the fluorescence of the paint is monitored with a camera. The paint fluorescence is a function of the local temperature, and therefore, each pixel on the camera acts as a thermocouple.
CATEGORY
Binary paint is composed of two probes, a pressure sensor and a reference probe. The reference probe is used to compensate for errors caused by model displacement/deformation. It can also be used to compensate for temperature.

The PSG-3 is a four channel digital pulse/delay generator used for controlling the timing of experiment parameters and can be used as an experiment master clock or externally triggered (or gated) by an external event. The PSG-3 replaces the PSG-2 in the ISSI product line. Pulse width, delay, repetition rate, and other timing parameters are controlled by a simple user interface (or also by any web browser interface) and communication is via Ethernet or USB. Features - Two dual-channel independently programmable pulse generators (each PSG-3 has 4 total channels). The PSG-3 can produce two separate frequency outputs either synchronously or asynchronously. - Four high-current TTL level outputs extend the utility of this generator by allowing it to drive low impedance loads (50 Ohms) such as solenoids and drive logic over long cable runs - Browser accessible HTTP-interface (internal web-server) - Remotely programmable through Ethernet or USB via simple software interface (or HTTP-based API) - Multiple timing bases (ns, us, ms) - Multiple PSG-3s can be cascaded to increase the number of channels - BNC inhibit input (TTL high level) to allow the PSG-3 to be gated by an external source - User application controlled or external signal triggering - Firmware upgradeability through USB - 50 MHz maximum trigger rate (20ns delay resolution) - Divide-by-N from 1-255 - Input Trigger Threshold 0.05-5.0V - Simple LabVIEW® integration Ideal for laser timing systems, automated testing, and precision pulse applications.
