Profile: Carlen Controls, Inc. designs, manufactures and services feedback transducer systems for mill automation. We offer a single shaft mounted device as opposed to multiple belt drives and pedestals. Our electronic interface modules are used for connection to the control system. CC1200 digital pulse tachometer is used with drive motors requiring a hollow shaft for the passage of fluids to the drive load. CC1500 linear transducer was originally designed for steel mill screwdown position control, which requires a high degree of reliability in a hostile environment including heat, liquids and dirt, which is used in applications include coil cars, side guide positioning, down coilers and continuous casting position control. CC450-AE absolute encoder is used as a position feedback device where absolute measurement is required.
