Brand: Ashcroft Inc
Request Information

Free Shipping on Orders Over $365.72 USD

The Ashcroft® DXLdp Differential Transmitter uses patented Si-Glas™ technology, assuring precise measurement and control at extremely low dP pressures.

This model is virtually unaffected by shock or vibration. A perfect solution when critical pressure measurement is needed.
Features
  • The exclusive patented Ashcroft spoolcal actuator provides in-place system calibration without disturbing process tubes
  • Front access test jacks provide on-line signal reference without removing wiring
  • LED range status indicators for instant troubleshooting information
  • DIN rail mount - dramatically reduces installation and calibration costs
  • 2:1 range turndown options
  • CE standard with all outputs
  • On-board voltage regulation allows use of lower cost, unregulated power supply
