CXLdp Differential Pressure Transmitter

CXLdp Differential Pressure Transmitter

The Ashcroft® CXLdp differential pressure transmitter uses the patented Si-Glas variable capacitance sensor, providing excellent sensitivity and long term stability.
The Ashcroft® CXLdp differential pressure transducer is designed for air handling applications including HVAC building systems, airflow metering and room pressurization control. It utilizes Ashcroft’s SiGlas™ technology that enables unrivaled measurement sensitivity and long term repeatability. The CXLdp 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. It is backed with a three year product warranty.
