1.Non-contact measurement small displacement (less then 2mm)
2.Measure and track small displacement in automatic control
troduction
TRLP series of linear small displacement sensor uses magnetoresistive sensing element and permanent magnet to achieve small displacement (less then 2mm) non-contact measurement. Its structure uses plate spring overhead device so as to eliminate the error caused by shaking and friction. The signal processing circuit uses temperature compensation circuit to reduce temperature drift possibly caused by temperature changes. TRLP-I model sensor can achieve current transformation of signal and output standard 4-20mA current signal.
