When to use a Real Thermal Switch not a Sensor

When CPI started making thermal switches for the Military in the 40’s, there really wasn’t any other choice. Thermocouple based switches with variable set-points and various temperature ranges of operation were made using the thermocouple materials of the day, mostly… Continue reading When to use a Real Thermal Switch not a Sensor

Military Grade Waterproof Switches

At CPI, we’ve been telling people for years about the robustness and reliability built into every USA designed and manufactured waterproof switch that we make. For applications from recreational vehicles, to advanced military and avionics applications, CPI switch hardware gets… Continue reading Military Grade Waterproof Switches

When Old Technology Becomes New Again – Part II

Two important considerations when looking at the integration of any hydraulic linear position sensor are the underlying technology and the packaging of the transducer. These principles effect size, life, maintainability, and above all, durability. The underlying technology used influences the… Continue reading When Old Technology Becomes New Again – Part II

When Old Technology Becomes New Again…

Interestingly when one looks back at the history of hydraulic position sensing technology some of the earliest ideas from as far back as the 1950’s revolved around both potentiometer based implementations and draw wire systems.  Potentiometer based systems with their… Continue reading When Old Technology Becomes New Again…

J4 Ball Switch – A Study in Hardness & Durability

Sometimes in engineering design, you just get it right. The right combination of materials, simplicity and elegance. Just the right amount of cleverness. Sometimes it even looks pretty. Sure as time goes on you make tweaks here and there, but… Continue reading J4 Ball Switch – A Study in Hardness & Durability

When Smoking is a Good Thing

If you work at TARDEC (the Tank and Automotive Research Development Center) you pretty much spend all day thinking about how to increase the survivability of ground vehicles during combat operations. In fact, the folks at TARDEC have created a… Continue reading When Smoking is a Good Thing

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… Continue reading Dump Truck Safety System Design

Dump Body Position Detection Gets National Attention

We’ve spoken in the past about the use of our limit switches as Dump Body position detection indicators, but recently this application was highlighted in a dramatically viral way. As Carlos Escobedo and his father were travelling down the East… Continue reading Dump Body Position Detection Gets National Attention
