Shop and search results
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.

Introduction To Building Management Systems
A BMS is most common in a large building. Its core function is to manage the environment within the building and may control temperature, carbon dioxide levels and humidity within a building. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimising heat/cooling losses.
Systems linked to a BMS typically represent 40% of a building\\\’s energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.
As well as controlling the building\\\’s internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for example, if a fire is detected then the system could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
Functions of Building Management Systems
The three basic functions of a central, computer-controlled BMS are:
the building’s facilities, mechanical, and electrical equipment for comfort, safety, and efficiency.
A BMS normally comprises of:
• Power systems
• Illumination system
• Electric power control system
• Heating,Ventilation and Air-conditioning HVAC System
• Security and observation system
• Magnetic card and access system
• Fire alarm system
• Lifts, elevators etc.
• Plumbing system
• Burglar alarms, CCTV
• Trace Heating
• Other engineering systems
• Home Automation System
• Fire alarm and Safety system
