Sensor 851S, LVDT displacement sensor
Swiss displacement sensors are used for measuring various lengths, diameters, thicknesses, height differences, runout, concentricity, and perpendicularity. The clamping method is simple, universal, accurate in measurement, and suitable for use in processing workshops.
Advantages of PETER LVDT sensor：
·Displacement guidance adopts ball bearings to ensure high accuracy of measurement
·Good linear error within the measurement range
·Various range sensors, including vacuum lift and compressed air drive models
·Good product compatibility (Mahr, Marpos)
·Mature half bridge and LVDT technologies ensure measurement stability and accuracy
·Over 10 million cycles of service life |
 |
Characteristics of PETER sensor:
·0-10.6mm with multiple strokes
·Unified φ 8h6 clamping straight handle
·The lifting drive includes precision spring form, vacuum lifting, and compressed air drive
·Standard hard alloy measuring ball, some sensors can replace the measuring head form according to personal needs
·Friction free, ball supported sliding measurement ensures durability and repeatability
·Adjustable force measurement
·Design firmly and continuously updated |
