Pressure
Quartz High-Pressure Sensor
for Ballistic Pressure Measurement to 6 000 bar
6215_000-043e-05.07
Type 6215...
The front sealed high pressure sensor surtable for ballistic pres-
sure measurement up to 6 000 bar.
NATO Standard
Extremely long service life
Very good long term stability
Description
Compared to the shoulder sealing used so far, the front seal-
ing technically improves the sensor considerably. The result-
ing main advantages are a considerably lower mechanical and
thermal stress of the sensor, no mounting gap (small dead
volume) and a largely reduced surface pressure in the sealing
part.
The Type 6215... has been accepted by NATO as the successor
to Kistler Type 6203 (AC/225 LG/3-SG/1). The existing NATO
Standardization Agreements (STANAGs) and Manuals of Proof
and Inspections (MOPIs) are being amended accordingly.
Application
Use for all ballistic measurements. Depending on the measur-
ing configuration, the sensor can be installed with an addi-
tional thermal protection shield or a diaphragm protection.
Mounting
The front seal allows the use of an additional attachment.
Figure 3 shows the installation with thermal protection shield
Type 6565A and thermal protective plate Type 1181A to re-
duce thermal shock error. For measurements in which the sen-
sor is exposed to heat over the entire pressure profile (e.g. in
pressure bombs and cartridge chambers).
Figure 4 shows the installation with diaphragm protector Type
6567. Recommended for measurements at the case mouth
and along the measuring barrel as protection against mechani-
cal damage from metal fragments and powder particles. It is
essential to follow the operating instructions when machining
the measuring hole and for installation.
