S+S REGELTECHNIK 1301-7111-4010-200

The 1301‑7111‑4010‑200 solves a critical need in HVAC, ventilation, clean‑room, and filter‑monitoring systems: the need for flexible, accurate, and easy‑to‑integrate differential pressure measurement. Many basic sensors cover only a fixed pressure range or lack direct output — but this transmitter offers multi‑range switching (±100, ±300, ±500, ±1000 Pa), making it suitable for light airflow detection, filter differential pressure monitoring, duct draft control or air‑handling inspections. omniray.ch+1

Because it outputs a standard 0–10 V (or optionally 4–20 mA) signal, it integrates seamlessly with automation systems, BMS controllers, PLCs or fan controllers — giving you real‑time, continuous pressure data without extra converters. The built-in display allows maintenance staff or technicians to read pressure values directly on site, aiding quick diagnostics and system checks. auteknik.com+1

The transmitter uses a temperature‑compensated piezoresistive sensor — this ensures long‑term stability and accurate results even when ambient conditions fluctuate, which is crucial in HVAC ducts or filter housings where temperature and airflow can vary. mwhandel.no+1 Its housing is impact‑resistant, weatherproof (IP65), making the unit suitable for installation in dusty or humid ventilation shafts, mechanical rooms or industrial environments. Manual zero‑point calibration (with optional auto‑zero) and offset adjustment further enhance reliability over time. smartone.ee+1

Overall, compared to simple fixed‑range sensors or mechanical gauges, the 1301‑7111‑4010‑200 offers more versatility, easier integration, and better long‑term reliability — making it ideal for modern HVAC systems, clean‑rooms, ventilation control, or filter monitoring in commercial or industrial buildings.
