+ Need Help Selecting a Pressure Switch?
Pressure switches are widely used by many industries and within many applications. The basic function of a pressure switch is to detect a pressure change and convert it into an electrical signal function – typically on/off or off/on. Pressure switches may be of electro-mechanical or electronic/solid-state design; and while each may have its advantages, arriving at the correct pressure switch for your application is the same. Learn more on how to select a pressure switch on our resource page.
+ Keeping Your Plant Safe with a Safety Instrumented System (SIS)
A Safety Instrumented System (SIS) is composed of a sensor, logic solver and final control element. These three components form a Safety Instrumented Function (SIF) that brings a process to a safe state during a hazardous event. Safety Instrumented Systems contain ten to hundreds of SIFs that make up the entire system and protect people, processes, equipment, environment and company image. Learn more about Safety Instrumented Systems on our SIS website.

+ What is The Sensor Box™
The Sensor Box™ can be your solution to expediting, high inventory and expensive downtime. One of the challenges in maintaining industrial temperature sensors is the variety. It is difficult for the typical process plant to stock every sensor configuration they might need to replace – until now. By combining common parts into a modular system, a relatively small amount of stock can translate into the variety you need – quickly, and without expediting. Learn more about The Sensor Box™ or watch our video, "Build A Sensor in Minutes".
