An experimental investigation of metrological characteristics of designed Universal Sensors and Transducers Interface (USTI-MOB) integrated circuit working in duty-cycle and duty-off factor measuring modes is described in the article. The USTI-MOB is based on the novel patented methods for duty-cycle – to – digital conversion. Experiments have confirmed the high metrological performance at low power consumption (0.35 mA current consumption at Vcc = 1.8 V). So, the relative error of duty-cycle – to – code conversion is changed from ±0.08 to ±1.00 % in all specified measuring range of USTI-MOB. Metrological characteristics and functionality make the USTI-MOB very suitable for various sensor systems designs, based on duty-cycle output sensors. In this case the significant time-to- marked reduction and design simplification can be achieved.
