Request InfoTT Electronics plcCARROLLTON, Texas, March 24, 2009 – Providing design engineers with a simplified means of detecting the presence of fluid in transparent tubing, TT electronics Optek Technology has expanded its family of fluid sensors to include automatic calibration circuitry and a preset trip level feature. Designated the OCB350 series, the sensors require only an optical device and a power supply for operation. They use an LED/phototransistor to sense the change in refractive properties between full and empty tubing as it passes through the sensor housing, creating multiple output states such as “fluid present,” “no fluid present” and...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueExtended InGaAs DetectorsHermetically sealed, surface-mount device-packaged 1.7- and 2.6-μm InGaAs PIN ATLAS photodiodes from Marktech Optoelectronics Inc. are designed for spacecraft, aerospace, medical, defense,...Photonics.com 12/12/2022Optical Sensing InterrogatorsFemto Sensing International has expanded its SX line of optical sensing interrogators for high-sensor-count fiber Bragg grating (FBG) applications.
