First out in the new “R” series line of fixed infrared sensors, this product is a non-contact temperature sensor designed for use in OEM equipment and industrial process control and monitoring applications.
Designed to measure IAQ, this product is a contamination-resistant optical sensor that enables accurate measurements throughout its projected lifetime of more than eight years. It measures 41 x 41 x 12 mm3 and fits in compact applications like wall-mounted or compact air quality devices.
To overcome the concerns of the mild flammability of A2L refrigerants, this product detects gas leaks for mixtures containing R-32. The device provides feedback to mitigation control systems and/or creates a shutdown process. This sensor core targets the R-32 gas concentration in the A2L mixtures; calculates the air volume concentration of the refrigerant gas; and relates it to the avoidance thresholds by levels of lower flammability limit.
These sensors accurately measure the relative humidity and temperature in commercial and residential buildings. Besides existing versions with analogue outputs, the devices are now also available with Modbus Rooftop Unit or BACnet interface, which facilitates integration into modern climate control systems.
This monitor measures CO2 and CO gases, temperatures, relative humidity, dew point, and wet bulb temperature. Compact and handheld, it has an easy-to-use menu system, immediate response time, magnetic rubber boot, PC software and USB connection, lithium-ion rechargeable battery, and optional CO sensor for safety.
The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announced the second public review of BSR/ACCA 15 OBD - 201x (On Board Diagnostic Codes for HVACR Equipment). The 60-day public review period begins March 16, 2018 and closes on May 15, 2018.
TUSCALOOSA, Ala. — Engineering researchers at The University of Alabama are part of a nationwide project to find ways of reducing energy used to heat, cool, and ventilate buildings.
Dr. Zheng O’Neill, UA assistant professor of mechanical engineering, is leading a team developing testing standards and control strategies for sensors used to control HVAC in commercial and residential buildings.
In this issue of The NEWS, we present the Residential Heating Showcase, featuring the latest heating equipment to hit residential HVAC. We also discuss developments in the tools and test instruments market.
