Type: Differential pressure transmitter with a metal sensor (welded metallic membrane) for measuring pressure differences. Accuracy: Typical reference accuracy ±0.10 % of span; in “PLATINUM” version up to ±0.075 %. Measuring range: From very low differential pressures (~0.5 mbar) up to about 40 bar. Turn-down ratio: Up to 100:1. Process temperature / ambient: Ambient approx –40 °C to +85 °C (for standard versions). Process connection temperatures vary. Output / communications: Typical 4-20 mA + HART; available also with PROFIBUS PA / FOUNDATION Fieldbus as options. Approvals / Safety: Certified up to SIL2 (functional safety) according to IEC 61508 / IEC 61511. Materials: Wetted parts in 316L stainless steel; membranes may be 316L or Alloy C. Application range: Flow (volume or mass) measurement (in combination with primary elements), level/volume/mass measurement in liquids, differential-pressure monitoring (e.g., filters/pumps).
