3.2.3 Installing the charge amplifier
Charge amplifier should be fixed with two vibrations
damping clamps as shown in the picture below. Select a
location where the temperature does certainly not exceed
110 °C. Route and fix the integrated cable between
sensor and charge amplifier so it is protected against
mechanical damage. Keep it away from any source of
heat such as the exhaust or hot fuel lines.
Picture shows an example of Charge Amplifier installation
with Stauff’s damping clamps fixed with clamp body with
rubber insert with film hinge. Clamp Assembly order code
is 419 PAR.
Clamp body, order code 4 PAR:
Standard type
Basic Material – Polyamide
Temperature Resistance -40 °C ... +120 °C /
-40 °F ... +248 °F
Rubber insert with film hinge, order code RI 19 (4+4S):
Exact outside diameter D = 19 mm:
Basic Material – Thermoplastic Elastomer (73 Shore-A)
Temperature Resistance -40 °C ... +125 °C /
-40 °F ... +257 °F
Recommended is to use a product that is intended for the
extra vibration/noise reducing installation of pipes and
tubes or the extra gentle installation of hoses and cables.
3.2.4 Cable between charge amplifier and data acquisition unit
We recommend using cable type 1700B69A…, which is
available in different lengths (for more detailed infor-
mation see datasheet of Type 7614CG1/CG2, doc. no.
003-044).
This cable can be made by the user. Use a shielded
cable; otherwise the sensor is not conform with CE rules.
The wiring must be done according to the electric block
diagram shown in chapter 5.2.5
