Designed to meet ASHRAE 15 and other building code requirements for mechanical rooms, MSA has released the new Chillgard® 5000 Refrigerant Leak Monitor. With the ability to read down to the 1 ppm level, MSA’s Chillgard 5000 provides an early response to HVAC refrigerant gas leaks, which allows maintenance crews to respond more quickly and to avoid the consequences and costs of hazardous gas leaks. Refrigerant gas is considered a toxic gas and although refrigerants have low toxicity, at high concentrations they can displace oxygen. Serious injury or death can result from worker oxygen deficiency.
Fluke Corp. has expanded the capabilities of its Condition Monitoring system to include thermal monitoring with the addition of the new Fluke® 3550 FC Thermal Imaging Sensor. Fluke officials said maintenance managers can now collect a more comprehensive variety of key-indicator data — thermal imaging, voltage, current, temperature, and power — on critical equipment to build a real-time picture of an asset’s condition.
Vibration fluctuations in HVAC systems are an early indicator of problems that cause equipment failure such as pump cavitation, unbalanced fans, and bad bearings. Sensaphone’s® new Vibration Sensor can be permanently mounted on equipment like generators, cooling towers, fans, and circulating pumps on chillers and boilers to continuously monitor vibration velocity and detect unusual conditions.
The Sensaphone® Airflow Sensor measures the rate of airflow and alerts data center managers when conditions fall outside the ideal range. The sensor monitors the presence or absence of cool moving air and provides relative airflow as a percentage from 0 to 100.
MEMSIC Inc. has created its MEMS based pressure sensor designed for VAV damper control as well as HVC applications such as room pressure monitoring, fume hood controls, furnace press switches, heat recovery systems, burner control, fan control, filter monitoring, and many others.
Engineered Systems magazine’s March 2019 issue examines the innovations offered by manufacturers at the 2019 AHR Expo and engineers at the ASHRAE Winter Conference, explores the difference between direct drive and belt drive fans in institutional applications, compares and contrasts the prescriptive and performance paths for boiler compliance, and much more.
