DXLdp Differential Pressure Transmitter

DXLdp Differential Pressure Transmitter

The Ashcroft® DXLdp differential transmitter uses patented Si-Glas technology, assuring precise measurement and control at extremely low dP pressures.
The Ashcroft® DXLdp differential pressure transducer is designed for use in high density panels in critical cleanroom, isolation room and control room applications. The DXLdp incorporates a DIN rail mount, LED status indicators and the patented Ashcroft SpoolCal® actuator to provide in-place system calibration without disturbing process connections. It utilizes Ashcroft’s SiGlas™ technology that enables unrivaled measurement sensitivity and long term repeatability. The DXLdp incorporates a host of features designed to reduce installation time and costs. It is also manufactured to Ashcroft’s straight forward TruAccuracy™ terminal point standard that eliminates confusion from statistically derived accuracy specifications and avoids the need for user calibration at the time of installation. Available in ranges as low as 12.5 Pa, the DXLdp is the perfect low pressure dp sensor for Pharmaceutical and BioTech applications, isolation laboratories, semiconductor and other mission critical  industries. It is backed with a three year product warranty.
