Description
Digital “Autozero & Span” option makes the pressure transmitter
TPSA Series a product extremely innovative and versatile. Designed thanks to the advanced electronics used by TPSA, this function allows zero and span adjustment in a simple, fast and reliable way, avoiding to use analogue trimmer, potential weak point and source of possible drifts or failures.
The starting is user friendly, simply touching the specific target mar- ked on the sensor body with a pen with magnetic head (included as standard).
Within few seconds the operation is concluded, without the need to dismantle or to open the instrument.
