LINEARIZED ALPHAPROX INDUCTIVE MEASURING SENSORS

Description

Baumer Ltd. has expanded its existing line of non-contact AlphaProx inductive analog proximity sensors to include new models with linearized output for a range of industrial measuring applications.  Designed to detect metallic objects at ranges up to 16mm, Linearized AlphaProx Sensors are cost efficient alternatives to more expensive sensor technologies, and can be used to detect changes in position, distance, thickness, weight or pressure.

Linearized AlphaProx Sensors feature a teach-in function that allows the user to adjust the usable measuring range and select the direction of the output slope.  Offering a resolution of 10 microns, these compact sensors can switch between analog and digital output. The Linearized AlphaProx Sensors feature two outputs that can be programmed by teach-in.  Output 1 is an analog output and Output 2 is a window output.

The sensors’ rugged IP67-rated chromium steel housings withstand harsh conditions and exposure to contaminents such as water, oil, dirt, non-metallic particles, dust, and fibers.  Linearized AlphaProx Sensors withstand high shock and vibration and can be used in operating temperatures ranging from -10ºC to +70ºC.

Linearized AlphaProx Sensors deliver long-term reliability in a range of industrial applications including aerospace, automotive, energy generation, food/beverage processing, heavy equipment, medical, metalworking, packaging, printing and textile manufacturing, as well as steel and wood processing.
