Described in this report is an analytical and experimental investigation of fluidic capillary temperature sensors and subsequent matching to a fluidic laminar gain block. Experimental sensor/gain-block sensitivities of 1.5 kPa/°C were obtained, which compared favorably with the analytical model. Assuming a dynamic range of 104 , resolutions of 0.001°C are estimated.
