Selectable Pressure Ranges

Model 2500 Model 7000
-100 to +100 Pa 0 to 1000 Pa
0 to 100 Pa 0 to 1500 Pa
0 to 250 Pa 0 to 2000 Pa
0 to 500 Pa 0 to 2500 Pa
0 to 1000 Pa 0 to 3000 Pa
0 to 1500 Pa 0 to 4000 Pa
0 to 2000 Pa 0 to 5000 Pa
0 to 2500 Pa 0 to 7000 Pa


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.
