Provided herein is a differential temperature sensor which utilizes multiple temperature sensors to quickly and accurately calculate ambient fluid temperature with a reduced response time. The provided systems and methods utilize a first fluid temperature sensor and a second probe temperature sensor to account for the thermal impact of the device on the ambient fluid temperature and the effect of heat within the device, or temperature difference between the probe and fluid temperature, on the first fluid temperature sensor measurement.

Fast response temperature sensors

Provided are turbidometers and fluorometers having a unique form-factor to accommodate a number of optical components in a confined geometry. This provides the ability to compensate for change in light intensity from an optical source even in a closed-loop manner. The ability to package reference and signal detectors, along with a relatively large diameter LED light source in a confined geometry is particularly suited for applications requiring small-diameter sensors, such as multi-parameter sonde devices having a total diameter that is in the sub-two inch range.

Compact sensor for measuring turbidity or fluorescence in a fluid sample

Methods and apparatus for system identification operate by computing phase and amplitude using linear filters. By digitally processing the linearly filtered signals or data, the phase and amplitude based on measurements of the input and output of a system, are determined.
