Linear position sensor TLH

conductive plastic potentiometeranalogmetal

Potentiometric position transducer without actuating rod with lengthwise coupling for reduced overall dimensions; metal wiper carrier; shear force free linkage via ball coupling; long life span TLH transducers are designedfor the direct, accurate measurement of displacement orlength in control, regulationand measuring applications.The rodless design utilizes amagnetically-restrained stainless steel band to cover theopening through which theactuator operates. Thus, theactuator is driven from theside, along the unit length.This allows the transducer tobe shorter, and permits strokelengths up to 3000 mm.A ball coupling limits parallel orangular drive forces from beingtransmitted to the sensorbearings.The TLH series is designedfor use with mounting clampswhich simplifies installationand adjustment. Due to the design and theselected materials the temperature coefficient of the transducer is extremely small.Careful attention to detail andchoice of materials has resulted in a transducer with anextremely low drift due totemperature.The robust design ensuresreliable operation even underharsh environmental conditionssuch as vibration ortemperature changes. Themeasuring technology is bothpassive and absolute.The TLH transducer is immuneto external electrical interference, and retains absolutepositional information in theevent of power failure.As with all potentiometers, theoutput is real-time.
