Overview
The PT420 series 4-20mA classic string pot is available with full-scale measurement ranges from 2 to 100 inches.
The PT420 series 4-20mA classic string pot provides position feedback on hydraulic cylinders in factories and utilities, gate position in fresh or wastewater distribution systems, or valve opening in process-related applications. The PT420 installs in minutes by mounting its base to a fixed surface and attaching its cable to the movable object. The PT420 works without perfect parallel alignment, and when its stainless steel cable is retracted, its height is less than 5”.
