A "burn building" is a structure that is built by local fire departments then, set on fire. The fire is intentionally set to determine how hot it burns, how quickly it spreads from room to room, how various contruction materials combust, what insulating materials may be best to use, etc. The image to the left is the lastest Burn Building Temperature Monitoring System. Pictured in front of the enclosure are special, high temperture sensors that are mounted through and behind walls within the burn building structure. This type of system may be designed with simple digital temperature indicators and / or with a multi-channel recorder for for data collection and analysis. 05/02/2008 2-Zone Infrared Temperature Monitoring & Control Panel This 2-zone temperature indicating & control system was designed to take 4-20mA signals from two IR transmitters and display both normal operating temperatures and peak temperatures of the processed parts. A DIN rail mounted power supply for the IR sensors and alarm relay outputs were also supplied as part of the system. The panel was prewired, calibrated, fused and tested prior to shipment. 10/18/2007 Wireless Water Pumping Control System A large military base requested that we help design a water level monitoring and control system. The system was an extremely simple concept. A person was to visually monitor water level in a holding pond. When the level got low, manually turn on pumps to refill the pond from the supply lakes. The tricky part was the pumps were close to the supply lakes - miles from the holding area and in a low lying area. By using wireless technology (transmitters, recievers & a signal repeater), the system was installed and working quickly without long, expensive runs of conduit, cable and hours of labor. Pictured at the left are the outdoor enclosures built to house all of the wireless equipment. 12/05/2006 2-Zone Heated Table & Control System Over the years, several customers have ask us to design & build heated tables. The applications for these tables have ranged from preheating plastic parts to heating valuable art work & paintings for restoration. Pictured at the left are the basic components used in our latest 2-zone system. Silicone rubber heating blankets are used for a smooth, consistant heat source and the custom control system is designed for high accuracy temperature & power control.
