Inductance Type Displacement Transducer. Waterproof. High resolution, less friction, and small measuring reactive force. A differential transformer is used for the sensing element to convert mechanical displacement to an electric quantity (voltage). Protected from external electrical effects with magnetism shielding . Stable against temperature change and durable. Used to measure changes in length, thickness, unevenness, and expansion/contraction within an object. Rated Capacity: ±100mm. Frequency Response: DC to 15Hz. Nonlinearity: Within ±0.5%RO. Safe Excitation Voltage: 5V AC (carrier: 5kHz). Safe temperature range: -15° to 70°C. Cable: 5m 4-conductor shielded wire. Overall size: 520mm L x Ø33mm core dia. x 65mm H x 60mm W. Weight, Approx.: 1.2kg.
