Product Type Smart Gauge Pressure Transmitter Output Signal 4-20 mA analog with HART Protocol (Rev 5/6/7) digital overlay Power Supply Loop-Powered (2-Wire). Operating Voltage: 12.5 to 36 V DC (Nominal 24 V DC). Measurement Type Gauge Pressure (Psig) Range Code (22) Must be confirmed via official range tables. For an IGP10 transmitter, 22 often corresponds to a range of 0-400 psi (0-27.6 bar). This is the most critical parameter to verify. Accuracy Typically ±0.1% of calibrated span (includes combined effects of linearity, hysteresis, and repeatability). Wetted Parts Diaphragm: Tantalum Flange: 316L Stainless Steel O-Rings: Viton® (Standard) or Kalrez®/FFKM (Option) Process Connection C1: 1/2" NPT Female Electrical Connection Not specified in model. Default is typically a 1/2" NPT conduit entry with a separate connection option code. Local Display None (Standard). An optional LCD indicator is available (would be denoted in model number, e.g., /M1). Ambient Temperature -40°C to 85°C (-40°F to 185°F) Process Temperature -40°C to 120°C (-40°F to 248°F) Protection Rating IP67 / NEMA 4X Safety Certifications Typically certified for hazardous areas by FM, FMc, ATEX, IECEx. Compliant with SIL 2/3 safety integrity levels. (Specific marks are on the product label).
