Technical specifications

Measuring range L depends on vector sensor type and collar thickness:

L=1.75×Dn+(Dn – Du), mm

where Dn – nominal collar thickness for sensor, mm;
Du – selected collar thickness, mm.

Linear displacement measuring accuracy:

±(0.02×Dn+0.01×|Dn –Du|), mm

0.1×Dn displacement measuring differential error within 0.5×L range:

±(0.03+0.002×Dn+0.01×|Dn –Du|), mm

DC-current output error, mA
