Pressure Sensors - PCB Piezotronics ICP 102M205 Installation And Operating Manual

1.0 INTRODUCTION
The series of miniature pressure sensors described by
this operating guide is designed for low pressure, high
resolution applications and features acceleration
compensation.
Uses include monitoring of low pressure hydraulic
and pneumatic phenomena in the presence of shock
and vibration such as on jet engines, compressors,
turbines and other operating machinery, high intensity
sound and turbulence measurements, and many other
industrial R & D applications.
2.0 DESCRIPTION
This series is comprised of six sensor models having
high sensitivities, but differing in mechanical
configuration.

Typical ICP Probe Style Sensor
Each model utilizes the basic ICP
shown in above figure. The pressure probe consists of
the Model 112A high sensitivity acceleration-
compensated quartz element and an IC source
follower amplifier joined together as an inseparable
assembly.

concept.
Models 112A21, 112A22 and 112A23 are in the
basic probe configuration as shown in Figure 1, and
are installed with a hollow clamp nut with 5/16-24
external threads. The housings of these models are at
electrical ground potential.
Series 111: Probe Style Sensor
The Model 102A05 utilizes the same basic pressure
probe, mounted in a 3/8-24 threaded mounting
adaptor with shoulder seal. The probe is assembled
into the adaptor at the factory in an "off ground"
configuration, i.e., the probe body is electrically
insulated from the external mounting adaptor body.
Do not attempt to disassemble probe and adaptor.
