Description
The Honeywell DCAL401GS is a high-performance low differential pressure sensor designed for critical applications in HVAC, medical equipment, and industrial automation. It delivers precise and reliable pressure measurements, ensuring optimal system control and enhanced operational efficiency in demanding environments.
Product Details
The Honeywell DCAL401GS is a professional micro-pressure gage sensor from Honeywell’s well‑known Micro Switch product line, engineered to deliver accurate and reliable low-pressure detection in various demanding environments. It operates on a 4.25 VDC power supply and supports a pressure range of 0.04 PSIG, making it ideal for applications requiring precise micro-pressure measurement.
This sensor adopts a 4‑pin SIP (Single In-Line Package) structure, enabling easy PCB mounting and integration into compact control systems. Its standard 0.19‑inch pressure port supports convenient tubing connection for air or non‑corrosive gas media. The device features high sensitivity, low thermal drift, and strong electromagnetic compatibility, ensuring stable output signals even in harsh industrial and HVAC environments.
Typical applications include airflow and static pressure monitoring in air conditioning and heating systems, pressure feedback in gas furnaces, leak detection in pneumatic components, and precise pressure control in medical equipment. It serves as a reliable replacement and upgrade part for many Lennox, Carrier, Trane, and York HVAC systems, helping maintain system efficiency, safety, and stable operation.
Honeywell DCAL401GS combines compact size, high precision, and durable performance, making it a preferred component for manufacturers and maintenance technicians in the HVAC, pneumatic control, and medical device industries.
