Miniature measuring probe for direct mounting or mounting
in a glow plug adapter, resulting in an extremely short
gas duct.
It can also be used in multivalve engines with small displacement. For the front diameter of only 4 mm, a measuring bore of 5 mm is sufficient. The probe mounts easily, after only slight modifications of the cylinder head, even across cooling water ducts, whereby sealing is assured by O-rings.
In the Type 6057A, a new piezoelectric crystal is used
which gives the sensor of unchanged size a sensitivity of -15 pC/bar. This will vary at most by ±1.5% within the
temperature range of 200 ±50°C. The front sealing guarantees efficient heat dissipation and therefore a short-time maximum
operating temperature of 400°C.
The miniature pressure probe performs measurements under critical space conditions in the engine combustion chamber: multivalve engines, motorcycles and small engines. For indicating cylinder pressure in diesel engines with glow plug adapter.
• Resistant to knocking
• Especially for indicating with glow plug adapter
• Low thermal shock error thanks to front sealing
• Very high sensitivity thanks to new piezoelectric crystal
