The WJL1 series is a line of displacement transducers manufactured by BCM Sensors Technology. The transducers are suitable for measuring linear displacement, with a range of 10mm to 30mm. The tool features a compact and lightweight design in a rigid construction. When the unit is powered with 10V DC constant voltage, its output signal is 10mili-volt. The device also provides accurate measurement suitable for most applications involving linear displacements measurements. The transducer probe is made out of stainless steel with an aluminum alloy housing, and strain gauge technology.
