Sensor Box™

A Modular Temperature Sensor Assembly System For The Instrumentation Maintenance Professional



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.

The Sensor Box

You Have A Problem...


3:00 PM on a Friday afternoon, and you’ve just discovered a temperature sensor has failed in an important process. The Safety Engineer wants the process shut down, but you’re under pressure to keep production moving. You’re going to spend the rest of the afternoon in “Panic Mode,” calling every sensor supplier you can  think of, begging for the best delivery at a premium. Not very pretty.


If this sounds familiar, then the SENSOR BOX™ was developed to help improve your life. Maintenance or instrument technicians can now build a new temperature sensor assembly, install it and the plant can be back up and running in minutes rather than days! The SENSOR BOX™ is designed for any plant where temperature sensors are an important part of the operation, and downtime is not an option.



The Sensor Box

The Sensor Box™ provides the Process customer with an alternative to expediting, emergency orders and large amounts of “dead” inventory. A modular system of sensors, hardware and tools, the Sensor Box™ is used by the maintenance professional to build a variety of temperature sensor assemblies on-site, in minutes. Among the benefits that customers report are:


  Improved Process Up-time

  Greatly Reduces Expediting, Emergency Orders and Premium Charges

  Fewer Emergency Orders

  Lower, More Flexible Inventory


The Sensor Box™ can be customized in many ways to meet your specific needs.


Building Your Sensor Box


A Sensor Box™ is specified in three stages, to maximize its flexibility to your needs:

1. The foundation: the Tool Box and tools required to build sensors (everything you need will be close at hand!)

2. The sensor diameter(s) required – choose based on either 0.250” or 0.188” diameters (need both? Add parts as


3. The terminal heads required – choose either NEMA 4 or explosion-proof terminal heads (or specify option E99 and

    customize the box however you like!)
