MURPHY Exhaust Pyrometers Mechanical Temperature Gauges
排气高温表

排气温度过高是所有发动机的主要损坏因素。监测这种温度的好方法是使用高温计。排气温度过高是由于燃油/空气比升高或发动机中的燃油量超过了支撑它的空气量所致。这种情况可能是由于过度节流、空气滤清器脏污、不同的燃油、燃油系统故障、海拔高度变化、发动机失调和许多其他原因造成的。但不管是什么原因,高温计在严重损坏发生之前就显示出这种情况。Excessive exhaust temperature is a major damaging factor to all engines. The best way to monitor this temperature is with the use of a pyrometer. Excessive exhaust temperature is caused by an upset fuel/air ratio or more fuel in the engine than there is air to support it. This condition can occur as a result of over throttling, a dirty air cleaner, different fuels, a malfunctioning fuel system, change of altitude, an out-of-tune engine and many other causes. But whatever the cause, a pyrometer indicates this condition before serious damage occurs.

 

  • Single or dual port reading
  • 2% accuracy
  • Sealed construction
  • Temperature compensation
  • Easy to read scales

 

The Single 10705147 and Dual 10705146 Port Pyrometers monitor exhaust temperatures in all types of engines. The Dual Port Pyrometer can monitor each bank of a V-type engine allowing you to compare readings at all times. Both pyrometers feature an easy-to-read illuminated dial with scales in both Fahrenheit and Celsius. They require no outside power (except for dial lighting). Spring-loaded jewels and alloy pivots increase durability. Murphy offers pyrometer accessories such as thermocouples and wire lead assembly suitable for stationary or mobile engines, power units, agricultural and construction equipment, as well as marine and trucking.
