Auto Zero Element
The optional auto zero element allows the transmitter to perform as a maintenance free unit. The element automatically adjusts the transmitters zero point from time to time, this eliminates the zero point long term drift of the piezoresistive sensing element. Units without an Auto Zero Element will require a manual zeroing at least every 12 months.
