Key parameters
Measuring range
0.25 inH2O to 10,000 psi via permanently installed PPT-1/PPT-2 pressure modules (single or dual)
Accuracy
From ±0.1% to ±0.025% of span depending on range/module (low-pressure capacitive ±0.1%/±0.06%/±0.07%; medium/high ±0.025%/±0.05%/±0.1%)
Output
RS-232 digital interface; dual-line LCD display (no analog process output)
Supply
110 Vac/60 Hz adapter standard; optional 220 Vac/50 Hz, 100 Vac, NiCd or alkaline pack
Process connection
1/8 NPT female
Wetted parts
PPM1 non-isolated (clean dry gas); PPM2 316 stainless steel media compatible
