Description

 

Efficient measurement of degree of blackening in diesel engines

The Testo 338 is an electronic smoke pump that enables the busy engineer to quickly measure the levels of soot an engine is producing during planned or regular maintenance schedules.

Available in two configurations, with or without Bluetooth communications capabilities, the Testo 338 is easy to use, compact, robust, and fast to operate. It only requires one hand for use and with the touch of a button, and can link to printers via its IRDA port for record retention.

After the measurement, soot concentration (mg/m³) as well as the degree of blackening is displayed. This can be altered to display either as an FSN (Filter Smoke Number) or as a Bosch number.

Typical applications for the Testo 338 include:

  • Diesel power or heating engines
  • Ship-owning and ship-building companies on marine engines
  • Industrial engines/turbines
  • Mining and prospecting
  • Construction machines and land-moving vehicles

Modern technology for the highest level of convenience

For most diesel engines, the degree of blackening requires regular measurement. This is used to check whether prescribed limit values are being adhered to, and can also be used to identify problems inside the engine at an early stage.

Up to now, blackening measurements were carried out manually with a hand pump and a comparison table. Automatic measurements were only possible with stationary equipment or large measurement apparatus. testo have come up with a resolution to this problem.

The testo 338 is a mobile measuring instrument which allows you to measure the degree of blackening both easily and efficiently. It is the first and only mobile measuring instrument which measures the degree of blackening automatically, without any additional analysis. This enables an efficient and professional smoke-count analysis of the engine to be made in a matter of seconds, using one manageable, user friendly piece of equipment.

It contains an optical, a temperature and a differential pressure sensor. Together, these sensors create a consistent picture of the degree of blackening. The measurement results can be printed out and documented on site. In addition to this, the measurement data can be transferred to the flue gas analyser testo 330 or a computer via Bluetooth and stored there.
