TAKE CONTROL OF POWER AND ECONOMY GAUGES MADE IN USA!

For anyone driving a diesel rig, a pyrometer should be the first instrument considered. A pyrometer is used in a diesel application to measure the temperature of the exhaust at a specific point in the exhaust system. By monitoring this temperature, we can measure the vital signs of the engine operation. The most critical component of a diesel engine is the fuel injection pump. The fuel injection pump controls the timing, fuel mixture and tuning functions. Exhaust temperature is the best way to monitor the fuel injection pump. Pyrometer readings allow the operator to constantly monitor the engines "safe zone" of operation. By establishing high and low ranges for you particular vehicle combination, you can tow with complete confidence. Without this information, you are only guessing that the engine is marking its peak power or delivering maximum fuel efficiency. See details of the pyrometer gauge including installation overview.

Turbocharged?

Turbocharged diesels are becoming more popular all the time. Turbochargers enable and engine to produce substantially more power than a naturally aspirated engine by forcing more air into the combustion chamber. And all of this is accomplished without any substantial loss of fuel efficiency. Yet, due to the compression of air created by turbochargers, some engine functions become more critical. As more air is forced into the combustion chamber, the fuel mixture has to be enriched to keep the engine from running to lean.

The manufactures of your vehicle pay close attention to all the functions going on as turbo boost occurs. Your turbocharged engine is designed to operate at certain boost levels to provide you with optimum performance and economy. A turbo boost gauge will let you know if you're operating in this "proper range". You'll also be able to determine if you are having a malfunction so you can head off damage to your turbo by having it serviced at the first sign of a malfunction.

How important is vacuum

In a gas engine, engine vacuum is your measuring stick for engine efficiency. For decades, vacuum gauges have been used to improve driving habits by those who know how to use them. The have even been offered as optional equipment on new cars from Detroit, marked in "green zones" for the driver to use as a guide for how hard to push down on the gas peddle. The rule of thumb is, the more vacuum your engine is pulling, the better. By being able to monitor the vacuum, you can adjust the throttle pressure you keep on the gas to significantly improve mileage and performance. And you might be amazed at the benefit you'll realize in towing applications as the vacuum gauge will enable you to better utilize your gearing. With the popularity of auxiliary gearboxes in the last decade, drivers now have up to ten gear ratios available. Just select one that gives the highest reading on the vacuum gauge (within the engine rpm range, of course) and the results on your fuel usage will be surprising. See details of the vacuum gauge.

Fluid temperatures

All internal combustion engines have a "sweet zone" of operational temperature where the components are designed to perform at their best. Critical in both gas and diesel engines, this is the temperature range at which all of the operating systems of the vehicle are designed and engineered to provide the most efficiency and extended service live. Not exceeding these temperatures, especially for long periods, is crucial to the life of these components.

Transmission fluid temperatures are critical. Unlike the radiator fluids which cool quickly, automatic transmission fluid can heat up rapidly and take a long time to cool down. The fluid serves three purposes in the transmission. It acts as a hydraulic fluid, it cools, and it lubricates the internal moving parts. Insufficient transmission cooling can cause premature wear or complete transmission failure. By periodically eyeing your transmission fluid temperature gauge, and knowing what you "high" should be, you will be able to recognize a problem developing before it becomes critical. See details of the temperature gauge.

Thermocouples

Our Type "K" Thermocouples are housed in Inconel or Incoloy tubular housings, with isolated or grounded tip (hot junction). Thermocouple assemblies are offered in straight or right-angle bend configurations, with 1/8 NPT, 1/4 NPT or other mounting. Flexible, stainless steel braided leads can be provided in varying lengths, with popular terminations (i.e., ring lugs, type "K" connector). Extension thermocouple-wire lead sets are also available. Types "J" and "E" are also available.

Other than keeping the vehicle between the lines on the road, being able to monitor a vehicle's vital systems may be the most important task a driver can perform. Accurate instrumentation, and the knowledge to interpret the information they provide, are paramount to maximum performance and service of today's sophisticated RV's and tow vehicles. We offer a performance monitoring gauges for diesel & gas pickup trucks, a complete line of gauges and components allowing you to monitor the performance of your vehicle. Components are offered for GM, Chevrolet, Ford, Dodge and Chrysler pickup trucks including Blazer, Silverado, Duramax diesel, Dodge Ram diesel and Ford PowerStroke diesels. Gauges are offered as individual items and components allowing you to save money by purchasing only the parts you need to complete your instrument cluster. We offer Pyrometer for monitoring turbo output temperature, turbo boost pressure and other critical temperatures that are especially important to monitor in diesel operation.

Precise instrumentation is the lifeline to the mechanical happenings of your vehicle. We offer Hewitt instruments components that can keep you informed as to vital system functions. Hewitt instruments manufactures the finest automotive gauges available with aircraft quality, our gauges are designed with clean, easy installation and superb fit. Detailed gauge parts list and pricing schedule. Pillar and pod mount parts list and pricing schedule. In addition in the right hand panel of this page you can see the complete kits we offer.

Pillar mounts that we offer accommodate 2 or 3 gauge clusters, they are made of plastic and can be painted to match the interior of your vehicle. They provide a finished look, allowing wires or tube to be routed out of site. We offer both full pillar and short pod typed mounts. Vehicles with stock speaker in pillar are accommodated. Gauge cluster is turned at precisely the right angle to the driver, the 2 1/16" dia. analog gauges; instruments are easy to read, mounted to prevent the gauges from reflecting on the windshield at night. The gauge housing is constructed of heavy thickness material for a lifetime of service without warping or cracking. In short, you can depend on and be proud built-in appearance of your instrument system.

Towing

Let's look at a typical towing situation. You purchased a one-ton tow vehicle and had it outfitted with a fifth wheel to tow you "home on wheels". Essentially, you have the same drivetrain as the guy driving his pick-up like a car to and from work. That's why, after the initial vehicle purchase, you start modifying it to get it up to the task. And while you can make it work, you put you vehicle to the test in cross-country driving with your "home" in tow.

With a Diesel?

Diesel engines are wonderful in the right applications. But how do you know if your are getting the peak performance designed into your diesel engine? ..

With proper instrumentation, you'll know if your fuel injection is providing the right mixture or if the turbo is delivering the correct boost necessary for the performance the factory specified. Both are very important functions of a turbo diesel. But what's included in proper instrumentation and what does it tell you.
