|Preferred Label||Biospherical Instruments QSP-2155 underwater PAR sensor|
|Definition||A custom-built version of the QSP-2150 Quantum Scalar Irradiance PAR Sensor, the QSP-2155 is designed for use on Teledyne Webb autonomous underwater vehicles, such as gliders. It is electronically and functionally equivalent to the QSP-2150, developed for multi-parameter logging applications, but its housing is tailored specifically for glider use. It uses a scalar irradiance collector to obtain a uniform directional response over 3.6-pi steradians. A stainless steel encased optical light pipe guides flux from the collector to a filtered silicon photodetector, resulting in a flat quantum response over the PAR spectral region (400-700 nm). The sensor produces a digital ASCII output and uses a Teledyne-Impulse MCBH series connector. It uses a 24-bit analog to digital converter (ADC) operating at frequencies of 4 to up to 250 Hz. It has a stability (dark reading) of < 0.003 microE m-2 sec-1 and operates in waters depths up to 2000 m.|
