CXLdp Differential Pressure Transmitter

Product catalog summary

Introduction
The CXLdp Differential Pressure Transmitter is an innovative solution for low-pressure measurement, designed for building energy management and comfort control. It features a rugged ABS package suitable for DIN rail or standard panel mounting, and includes a LED power status indicator for troubleshooting and quick location on ducts.

Exclusive Features

Detachable Euro style terminal block to minimize wiring errors and reduce field wiring time.
19 standard pressure ranges, all capable of withstanding 15 psi without damage or calibration change.
Digitally compensated with NIST traceable accuracy models of 0.4% F.S. and 0.8% F.S.

Sensor Technology
The transmitter uses the patented Ashcroft Si-Glas™ variable capacitance sensor, a MEMS sensor known for its sensitivity and long-term stability. It is digitally compensated using a reliable application-specific integrated circuit (ASIC).
