24 May 2006 -- SensorsONE is launching the NEW digital autozero and span option for the Gefran TK industrial pressure transmitter and the TPSA precision pressure transmitter. The Gefran TKDA and TPSADA from SensorsONE incorporates an innovative and versatile zero and span trimmer which removes the need to manually adjust potentiometers or purchase expensive proprietary handheld terminals to set the 4 to 20mA current output. All pressure sensors drift over time and the main component of drift is contributed by the change in zero offset.
The Gefran Digital Autozero from SensorsONE makes it very easy to perform a zero adjustment as often as necessary to ensure the most accurate pressure measurement.
Digital autozero and span works by simply placing a magnetic pen close to a marked target on the body tube of the pressure transmitter and by following the calibration procedure steps the pressure sensor can be calibrated very quickly without any fiddling with pots or without any need to connect handheld computers or PDAs.
The 4-20mA output zero can be coarse trimmed up to +/-10% full scale, and fine trimmed to a resolution of +/-0.075% full scale.
