CPI Thermals Help Young Pilots, Fly Safe

Embry Riddle Aeronautical University has long been a staple of aviation education across the United States. Formed in 1925, It is the largest accredited university system specializing in aviation and aerospace. It has multiple locations with its primary campus residing in Daytona, Florida. One of the many planes Embry Riddle uses is the new Diamond Aircraft DA42 L-360. This twin engine propeller plane from Austrian company Diamond Aircraft was chosen because it offered so many advantages


Weatherproof Switches, More Than Just Waterproof.

In the world of industrial grade weatherproof switches, you have to worry about more than just water mixing with your electrons. Mac Stuhler, Vice President of Business Development for CPI, puts it this way. “We learned a long time ago that manufacturers were buying our switches because they are waterproof, but that they were going into applications that required many more dimensions of robustness to be viable solutions.” Over a period of 70 years, CPI has


CPI Waterproof Switch Panels

It’s not much of a stretch to take some of our panel mountable waterproof switches and package them into a custom panel that can be provided to manufacturers as a complete assembly. Many manufacturers find this more cost effective than doing the work themselves and we also become responsible for the testing and wiring of the switch and any special termination connectors, another headache removed.

Dump Truck Safety System Design

The design of the modern work truck is moving forward at an amazing pace. With long haul trucks, the focus has been on collision avoidance systems and advanced controls for fuel economy, but dump truck builders have long had a different focus. For Dump Trucks, it’s all about safety. Historically, makers of class 8 dump trucks have not exactly been “early adopters” of technology, preferring instead to allow these


Lift Controls Reach New Heights With CPI Switches.

One of the more overlooked uses of CPI’s line of waterproof limit switches may be its selection for a wide variety of outdoor, harsh duty lift activation systems. These systems have a number of attributes that make CPI waterproof pendant switches a perfect solution:

  1. Lift switches are often hand actuated by humans.
  2. The switches are exposed to outdoor conditions of wind, dust, oil splashes or heavy rain or salt spray.
  3. The switches are


Top 5 reasons Your Waterproof Switches … Aren’t.

Engineers searching for electromechanical switches that are truly waterproof are generally doing so for a few common reasons:

  1. Their switch will be used outdoors. (ie. Lawn mowers, generator, etc…)
  2. Their switch may be fully submerged for periods of time. (Military Humvee’s, recreational vehicles, boating applications)
  3. Their switch has to be both waterproof and heavy duty to avoid general failure due to salt water, wind, sand spray, and other airborne or liquid particulates that may be


Thermal Switches for Military and Commercial Jets

In a past life I was privileged to work on the very first fly-by-wire system used on the F16. This was the first system of its type used in an operational jet fighter utilizing a quad redundant custom designed CPU and optical fiber to relay cockpit commands to control surfaces in a matter of milliseconds. Since then there have been thousands if not millions of improvements large and small to the F16 which remains a staple


Valve Position Sensing for Mission Critical Flow Applications.

Systems like municipal water supplies, sewage treatment plants, massive cooling and lubrication systems used in chemical, petrochemical, and the oil and gas industry, all share one thing in common: large flow valves that are critically opened and closed by computer controls to insure proper system operation, or prevent critical safety thresholds from being violated. Flow rates in these systems can be 10’s of thousands of gallons per hour at high pressure so valve control has
