Reflective /Infrared Sensors Help Control Product Flow on Conveyors
Intended for zero pressure accumulation applications, SICK’s recently launched R/IR sensors are designed to be mounted between the rollers on conveyors where mounting space is limited. The mounting location makes the sensors less susceptible to damage. Members of the company’s ZoneControl line, the sensors help control product flow on conveyors, reducing jams and allowing product […]
Detect the Presence or Absence of Liquid in a Transparent Pipe
Using through-beam sensing technology with a 950-nm infrared LED, Autonics BL Series liquid level sensors can accurately detect the presence or absence of liquid in a transparent pipe. This could be for a critical monitoring situation in process control or other applications. For this approach to work, the W23 X H14 X L13-mm sensor requires […]
Affordable Thermal Imager Announced for Smartphones
At CES 2014, thermal imaging company FLIR announced the FLIR ONE™ personal thermal imaging device that targets consumer applications. The non-contact device detects infrared (IR) energy (heat) and converts it into an electronic signal for displaying a thermal image on a smartphone screen and performing temperature calculations. In its report on “Uncooled Infrared Imaging Technology […]
Google’s Acquisition of Hardware Supplier Advances IoT Connectivity
With Google Inc’s announcement of its plans to acquire Nest Labs Inc, the Internet of Things (IoT) received a tremendous boost. Nest Labs makes smart thermostats and smoke alarms that have a high degree of connectivity. The Nest Protect smoke alarm uses six sensors: photoelectric smoke sensor, carbon monoxide (CO) sensor, heat sensor, light sensor, […]
Rugged IR Sources for Gas Sensors
Infrared (IR) sources are used for gas detection in a variety of measurement techniques including non-dispersive infrared spectroscopy, (NDIR), photoacoustic infrared spectroscopy (PAS) and attenuated-total-reflectance FTIR spectroscopy (ATR). For its IR sources, Axetris uses micromachined, electrically-modulated, thermal infrared emitters to detect CO, CO2, VOC, NOx, NH3, SOx, SF6, hydrocarbons, humidity, anesthetic agents, refrigerants and breath […]
