Model Number P0972QL Product Type Gauge Pressure Transmitter Pressure Type Gauge Pressure (pressure relative to atmospheric pressure) Sensor Technology Silicon Resonant Sensor Output Signal 4-20 mA analog output with superimposed HART® Protocol for digital communication. Accuracy High accuracy, typically ±0.075% of the Upper Range Limit (URL) for most of its range. (The "QL" often denotes a range that supports this high accuracy). Long-Term Stability Excellent, typically ±0.1% of URL per 12 months. Pressure Ranges (URL) The "QL" suffix specifically indicates a different Upper Range Limit than the "QR" model. For example, while "QR" might cover a very high range, "QL" could indicate a lower or medium pressure range (e.g., a common QL range is 0-100 kPa / 0-15 psi). The exact value must be confirmed via the datasheet or nameplate. Process Connection Standard: 1/2-14 NPT internal thread. Wetted Parts Material 316L Stainless Steel (standard for diaphragm and process connections). Power Supply 2-wire, 12-45 VDC (loop-powered). Operating Temperature Electronics: -40°C to +85°C (-40°F to 185°F). Process Media: -40°C to +125°C (-40°F to 257°F). Protection Rating NEMA 4X / IP67 (weatherproof, dust-tight, and corrosion-resistant).
