IXLdp Differential Pressure Transducer
The Ashcroft® IXLdp industrial differential transducer is used for measurement and control of extremely low pressures and flow. Using patented Si-Glas⢠technology, performance provides high sensitivity and repeatability for precise measurement and control at extremely low differential pressures. An ideal choice when stable, reliable pressure measurement and TruAccuracy⢠performance are needed.

Key Features:
- TruAccuracy⢠performance ensures the IXLdp meets its rated accuracy out of the box and is ready for installation with no additional calibration adjustments required.
- Rugged enclosure
- Wide selection of output signals and differential pressure ranges down to +/- 0.05 in. H2O
- Integral electrical termination isolates electronics from the process connections
- Optional FM approval for hazardous locations
- Outstanding overpressure protection
- Wide operating temperature capability
- Superior long-term stability
- 3-Year Warranty
- FM Approval optional
