T3030 Series CO2 Sensors for Harsh Environments with Analog Outputs

Product Overview

The Amphenol Advanced Sensors Telaire T3030 Series is a range of Carbon Dioxide (CO2) Sensors specifically engineered for measuring CO2 in harsh or difficult environments. These accurate CO2 transmitters are designed for HVAC control applications and offer easy mounting with two external tabs. Built to withstand demanding conditions, they are rated up to IP67 (build dependent) and are available with optional potting for enhanced protection. The sensors utilize Non-Dispersive Infrared (NDIR) measuring technology and are factory-calibrated, offering accuracy for a 10-year life and an extended operating temperature range. Applications include incubators, buses, refrigerators, subway stations, railway carriages, and agricultural settings like glass houses, mushroom sheds, and animal sheds.
