Our Multi-Circuit Monitor power monitoring system provides a convenient solution for monitoring multiple electrical services which share a common voltage source. It also reports diagnostic information such as power factor, volts, amps, and kVAR, over an RS-485 network using the industry standard Modbus® communication protocol. To protect valuable equipment, it has built-in alarm registers for over- and under-voltage, current, and kVA.

The monitoring capabilities and open systems compatibility of the H8238 make it the ideal power monitoring solution for OEM, tenant submetering applications, and load management of power distribution units commonly used in internet data centers. The meter is a UL508 open type device without enclosure.

Introduction

Ever since the first commercial thermal imaging camera was

sold in 1965 for high voltage power line inspections, by what

would later become FLIR Systems, the use of thermal imaging

cameras for industrial applications has been an important market

segment for FLIR.

Since then thermal imaging technology has evolved. Thermal

imaging cameras have become compact systems that look just

like a digital video camera or digital photo camera. They are easy

to use and generate crisp real-time high-resolution images.

Thermal imaging technology has become one of the most

valuable diagnostic tools for industrial applications. By detecting

anomalies that are usually invisible to the naked eye, thermal

imaging allows corrective action to be taken before costly

system failures occur.

Optional VAV Accessories for use with ZN Line modules

The ZASF is part of a family of control modules designed specifically for VAV terminal box applications. It is designed to be used with the ZN341v+ and ZN141v+. It mounts directly on the secondary VAV damper shaft and provides an integral actuator and a second integrated flow sensor for damper positioning and air-flow sensing in dual duct or tracking systems.

Balancing Efficiency with Comfort

WebCTRL Environmental Index – Balancing Efficiency With Comfort

As energy prices continue to soar, facility managers are under increasing pressure to find ways to cut building operating costs. A simple solution would be to decrease energy consumption, but smart managers know that sacrificing comfort for energy savings could lead to even bigger financial problems. After all, studies have shown productivity decreases as comfort levels decline, leading to lost revenues in companies and difficult learning environments in school systems. What’s needed is a way to measure comfort, so managers would know exactly how far to cut energy usage without negatively impacting comfort.

Automated Logic’s Environmental Index provides the solution. Since the key component of comfort is temperature, ALC’s index starts with assigning point values based on the difference between zone temperature and heating and cooling set points. Other factors, such as humidity and CO2 levels, can also be computed into the numeric system to reflect one “comfort” score for all factors. This is a powerful tool for facility managers who need to identify buildings with performance problems or ensure buildings don’t become less efficient as changes are made.
