Note:* Improved accuracies of 0.25% F.S. and 0.1% F.S. are available for many ranges. Please refer to data sheet
Note:** mV/V and V/V output sensitivities are dependent on stroke length. Specific data sheets have output tables.
Stellar Technology provides a selection of DIN-rail mount signal conditioners to compliment our AC/AC LVDTs. These products provide valuable complementary solutions for those applications requiring high level analog outputs and where the LVDT may be exposed to conditions detrimental to internal signal conditioning or the required LVDT configuration will not accommodate an internal amplifier.
