SPECIFICATIONS
| Sensitivity | Less than .001 psi (±.02 inH2O .508 mm water) |
| Repeatability | Better than ±.002 psi (± .05 inH2O/ 1.27 mm water) |
| Accuracy | ±.007 psi (±0.2 inH2O / .508 mm water) |
| Temperature range | 30 ° F to 300 ° F (0 °C to 149 °C) |
| Pressure range | Sensor is a 1:1 pneumatic force balance diaphragm capable of repeating hydrostatic pressure as an equivalent pneumatic output. Functional pressure limit is 130 psi (or 3598 inches @ 1.00 specific gravity) determined by supply pressure (35–150 psi) less 20 psi. |
| Maximum depth measurement | 1937 inH2O (49.0 m water) |
| Wetted materials | Silicone rubber O-ring (meets the requirements of 3-A) Titanium diaphragm, commercially pure (meets the requirements of 3-A 74-07). Optional diaphragm materials: Silicone rubber Fittings/adapter wetted surfaces are typically 316L Stainless Steel (as supplied by KING-GAGE). |
| Air consumption | Total air consumption of sensor package (including sensor control) is less than 10 CFH or 0.16 scfm. |
| D/P sensor control combined accuracy* | 0 psid to 5 psid transmitter/control ±0.34% full scale 0 psid to 10 psid transmitter/control ±0.27% full scale 0 psid to 15 psid transmitter/control ±0.24% full scale 0 psid to 30 psid transmitter/control ±0.22% full scale 0 psid to 50 psid transmitter/control ±0.21% full scale |
| Voltage supply requirements | 14 Vdc tp 40 Vdc (unregulated) to power signal loop using 868 D/P Sensor Control. |
| Compressed air supply requirements | 35 psig to 150 psig (2.4–10.3 bar); clean, dry air (or inert gas) |
* Combined accuracy refers to the primary accuracy of the sensor in combination with the secondary accuracy of the D/P transmitter.
