XS-ZTR series LVDT

Product Description

The XS-ZTR Series of LVDTs were specifically designed for measuring displacements in extremely high and very low, cryogenic temperature environments. The XS-ZTR will operate continuously from -320 to +1020ºF [-195 to +550°C], and will survive non-operating temperatures of up to +1200F [650°C]. It is also capable of performing within specification after radiation exposure to a total integrated neutron flux of 3 x 1020 NVT or 3 x 1024 n/m2 , and gamma-ray total integrated dose radiation of 1011 rad or 109 Gy. The XS-ZTR is made exclusively from inorganic materials, specifically selected for their compatible expansion coefficients in order to minimize thermally induced stresses. The coil windings are of ceramic insulated precious metal alloys, while all seams and joints are either welded or brazed with high temperature alloys. The leads are sheathed in stainless steel, with conductors composed of nickel with magnesium oxide insulation. These cables can be terminated to a sealed header or connector if required. As most inorganic insulation materials are hygroscopic, the entire coil assembly is hermetically sealed inside a stainless steel case. This prevents moisture accumulation, insulation leakage, and protects the coil from hostile surrounding media while allowing the core to move freely. The XS-ZTR Series is compatible with all Measurement Specialties LVDT signal conditioners, controllers and readouts. For moderate temperature and radiation applications, consider using our HR-Z series LVDT, mild radiation resistant.
