Model Foxboro 873RS-AIPCGZ Type Absolute Pressure Transmitter Output Signal 4-20 mA DC analog with superimposed HART® protocol (digital) Power Supply 10.5 to 42 V DC (loop-powered, typical 24 V DC) Housing Rating Explosion-Proof / Flameproof - Class I, Division 1, Groups B, C, D (North America) - ATEX / IECEx: Ex d IIC T6 Gb (Europe / International) Enclosure Material Cast aluminum with a black epoxy finish. Sensor Technology Silicon Capacitive (High Accuracy) Performance / Accuracy ±0.1% of calibrated span (includes linearity, hysteresis, and repeatability). This is a high-accuracy version. Process Connection Typically 1/2" NPT female (or other as specified by "GZ" suffix). The "CGZ" code often includes 316L SST wetted parts. Pressure Ranges (URL) The "RS" indicates a specific range series. Common URL (Upper Range Limit) values are 100 inH₂O, 500 inH₂O, 1000 inH₂O, 3000 psi, etc. The exact URL is defined by the order code. Adjustable Span Up to 100:1 turndown from the sensor's Upper Range Limit (URL). Ambient Temperature -40°C to +85°C (-40°F to +185°F) Process Temperature -40°C to +120°C (-40°F to +248°F) (with standard fill fluid) Stability ±0.1% of URL per year for 10 years. Display Optional Local Operator Interface (LOI) can be mounted on the transmitter for local readout and configuration.
