The Focovision by Transmission SPV-3 is used in prescription laboratories. It is connected to your computer network, from which it receives the nominal values of the prescription lens. Its main advantages are repeatability, accuracy, easy calibration, and especially its visualization system of the semivisible marks or the upper segment line corner of the addition. This system permits an accurate positioning on the different control points without any lens marking. It measures the lens optical power by using a light beam perpendicular to the concave lens surface at a certain wavelength (546 nm or 587 nm) and by measuring in all directions (360 degrees). In addition, it has a user friendly interface permitting an operator to learn how to perform the complete lens control (far view, prism reference point, near view, thickness, shape, etc.) with little training required. Minimal training required Very high measurement speed Flexibility (configurable procedures, easy to adapt, any toleran

Clippard's EFB series electronic fill and bleed circuits are a combination of Clippard pneumatic valve components used to inflate a volume or apparatus in one controllable function, and to release or vent pressure in a second controllable function. Fill and bleed circuits are commonly used in many applications where a particular pressure, firmness, or position can be controlled with the addition or venting of pressure. • Compact, robust design • Extremely fast response • Exceptionally long life • Multiple flow and pressure options • Variety of power and connection options • RoHS compliant Read More about the EFB Series Configure & View Products

ExxonMobil’s Wet Gas Scrubbing (WGS) technology allows refiners to reliably meet tough FCC emission regulations with well-proven technology.In 2002 and 2003, ExxonMobil Research and Engineering Company (EMRE) and Hamon Research-Cottrell (HR-C), entered into licensing and sublicensing agreements to provide ExxonMobil’s Wet Gas Scrubbing technology to sublicensees of HR-C.Expect these advantages:Can avoid costly CO boiler upgrades with allowable scrubber pressure drops as low as zero inches of water, Takes advantage of HRC’s almost 100 years of experience and global leadership position in providing air pollution control equipment to a wide range of industries, including refineries.Maximizes cat cracker availability - scrubber run lengths match longest FCC up-time in the industry, Meets or exceeds toughest particulate and SOx emission regulations, Produces environmentally benign wastewater safe for direct discharge, Collected catalyst suitable for direct low cost disposal

This 3-step control switch regulates EC fans, damper actuators, AC fan speed controllers or frequency inverters. It needs 10 VDC supply voltage. The device has an OFF position to stop the motor completely. Thus, the output signal is divided into 4 steps: 0 VDC and 3 other output voltages. The output for position 3 always equals the supplied voltage i.e. 10 VDC. The output ranges for positions 1 and 2 can be adjusted via internal trimmers. There is also a version with 2 predetermined voltage steps: SMT-D-4P-EM
