Level sensor

By Design News Staff -- Design News, October 5, 1998

Model OLS-12 optical level sensor provides a rapid response to change of liquid level and a stable process control with no moving parts to grind or wear out. Designed for corrosive applications, the pfa-grade Teflon unit's bright green and red LEDs offer local indication for the presence or absence of liquids. This sensor incorporates an NPN open collector output signal. Current consumption is 35 mA dc maximum, and power supply is 10 to 28V dc. Leads are 22 gauge and 18 inches long with tinned ends.

Light Matters: A High-Performance, "No-Compromise" Solid State Lamp?
First, let's define "no-compromise". In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package, and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
