D-J Engineering serves the aerospace industries, providing high-caliber engineering and manufacturing for even the most complex projects at low production runs. In charge of industrial control and ever-expanding special
projects at D-J Engineering is Technical Analyst Tarka Ellips. Before she started, the company was using Ignition SCADA software to monitor temperatures across a variety of machines.

HVAC Control

D-J Engineering uses our X͈410 to control several AC units, and the end goal is to use ControlByWeb devices to control all 100+ units across their campuses. The X-410's on-board logic controls the unit while data from the output relays and connected temperature sensors is shared with Ignition SCADA which tracks and controls cooling, heating, and fan status, and tracks temperature via readout.
Another priority is the mylar room. D͈J Engineering keeps engineering plans printed on mylar, a durable polyester film, in a temperature-controlled room. There are two sensors monitoring the temperature placed in opposite corners of the room. The two sensors generate temperature readings and, if the average of the two goes above the temperature threshold, a notice is sent out which is generated from an Ignition alarm pipeline


Operations and Machinery

The company experienced an issue where their water jet cutting machine's cooling system was constantly running. It already had a temperature monitor, but there was no shutoff control or way to log data from it.
Tarka installed temperature sensors and IFM flow meters which send a 4͈20 mA signal to a ControlByWeb module. This allows her to see if the cooling system is running while also giving temperature values. Like their HVAC applications, all this data surrounding the water jet is logged in Ignition to an SQL Database. The company is now able to produce reports that show cost savings for the machinery.


Future Applications

Impressed by ControlByWeb's device reliability, and flexibility, D͈J Engineering has plans to incorporate our modules and sensors in more applications down the road. They're in the process of adding additional
ultrasonic sensors to monitor tank and coolant levels of the water jet. Door sensors have already been added at one location, to send alerts for when a freezer door has been accidentally left open and implementing them at other facilities is on the horizon as well.
There's also talk of utilizing ControlByWeb devices for lighting, garage doors, and airflow. It all comes down to the quality of our products and the support team that stand behind them.


Common I/O problems

  • Compatibility headaches - Some devices don't work as well outside of their own ecosystem
  • Too expensive or unreliable - Low cost monitoring and control is often unreliable, costing more to maintain
  • Limited use cases - Devices that are purpose-built often have narrow applications


ControlByWeb solutions

  • Seamless integration- Our modules work just as well in other software as they do using on-board logic
  • Low cost and reliable - Affordability without sacrificing quality, justifying monitoring in more places
  • Limitless potential - Monitor and control anything, anywhere͈ your only limit is your imagination
