To determine the temperature range you require, consult with your vehicles manufacturer for the operating exhaust temperature under normal conditions. If your vehicle doesn't currently have a Pyrometer, you will need to consult with your mechanic on what will be required for installation on your particular equipment.

WHY IS A PYROMETER IMPORTANT? (top)

  • Pyrometers measure exhaust temperature to verify maximum allowable operating temperature and protect the vehicle's engine from over-heating and potential damage. For example: When hauling a heavy load up a hill, a pyrometer will give a quicker indication of an overheating situation than monitoring the engine cooling system temperature.
  • As a rule, heavy-duty applications - truck and bus, off-highway, marine - generate high heat. Pyrometers monitor temperature rise in critical high operating temperature environments.
  • Operator response time impacts throttle settings and lag causes wasteful over-correction. An incorrect setting may cause an over-temperature condition. Pyrometers help operators maintain optimal settings.
  • Pyrometers may indicate harmful over-fueling conditions as well. Over-fueling contributes to carbon build-up, lube oil dilution and higher operating temperatures.
  • Pyrometers help optimize trim settings in boats in order to synchronize motors.
  • Pyrometers help monitor applications with a so-called "dead load" that generate high temperature (e.g. tractors). Exhaust temperature is in direct relation to load.

FEATURES AND BENEFITS: (top)

  • Rugged, shielded, long-life pyrometer movement for faster, linear and accurate responses to changes in exhaust temperature
  • Works with grounded OR ungrounded thermocouples
  • Form-Fit-Function compatible with competitors' models for easy drop-in replacement
  • No external power required to drive pyrometer (except for illumination)
  • Popular operating temperature ranges
  • Black anodized or chrome-plated bezels
  • Single or dual-scale graphics, color coded for certain models
  • Light kits included for 2" and 3" models
  • Electrically dampened to minimize pointer over-shoot & flutter
  • Corrosion-resistant zinc-plated steel cases

GENERAL SPECIFICATIONS: (top)

  • 2.05" and 3.05" diameter products (nominal)
  • Eight popular configurations replace Isspro products
  • 1500° and 1800°F temperature ranges
  • Work with type "K" thermocouples
  • 100° and 250° pointer sweep
  • "Ruggedized" design for superior performance in heavy-duty applications
  • Superior flux distribution and magnet system generates more torque for faster response and accuracy
  • No external power required to drive gauge
  • Made in U.S.A.
