1.1
Introduction: Safety Considerations
WARNING 1:
The power supply/signal conditioner
should not be opened by anyone other than qualified
service personnel.
This product is intended for use by
qualified personnel who recognize shock hazards and
are familiar with the safety precautions required to avoid
injury.
WARNING 2:
This equipment is designed with user
safety in mind; however, the protection provided by the
equipment may be impaired if the equipment is used in a
manner not specified by PCB Piezotronics, Inc.
Caution 1:
Cables can kill your equipment.
High
voltage electrostatic discharge can damage electrical
devices. Similar to a capacitor, a cable can hold a
charge caused by triboelectric transfer, such as that
which occurs in the following:
Laying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact with a non-grounded person.
The solution for product safety: 1) Connect the cables
only with the AC power off. 2) Temporarily
“
short
”
the
end of the cable before attaching it to any signal input or
output.
Caution 2:
ESD considerations should be made prior to
performing any internal adjustments on the equipment.
Any piece of electronic equipment is vulnerable to ESD
when opened for adjustments. Internal adjustments
should therefore be done ONLY at an ESD-safe work
area. Many products have ESD protection, but the level
of protection may be exceeded by extremely high
voltage.
The
Caution
heading used in this manual explains
hazards that could damage the instrument.
1.2 Introduction
The Model 482B06 / F482B06 is a single-channel, line-
operated signal conditioner for use with ICP
®
sensor.
This unit provides a 24VDC, 4mA constant current
excitation to ICP® pressure, force or vibration sensors.
It also decouples the sensor
’
s DC bias voltage from the
AC measurement signal .
This unit also contains provisions for channel fault
monitoring, as well as a provision for externally varying
the constant current over a 2 to 20 mA range. This
model is factory set at 4 mA. ( Please refer the Model
482B06 / F482B06 specification sheet ).
2.0 Description
The Model 482B06 is powered by a 115V, 50-400Hz
AC line supply and the Model F482B06 by a 230V,50-
400Hz supply. The desired input power is selected by
using a switch located on the base. Other than that, there
is no difference in operation between the 482B06 and
the F482B06.
The rear panel contains one BNC jacks for sensor
INPUT and one BNC jack for signal OUTPUT
connection (refer Figure 3).
The AC measurement signal is decoupled from the
sensor DC bias by a coupling capacitor and brought to
the OUTPUT jack.
The bias or fault meter consists of a color-coded front
panel meter located on the front panel. The fault meter
reflect the measured sensor bias of that channel as being
in either the red, green or yellow. (refer Figure 1 and
section 3.0)
Please refer the sensor data sheet for specific sensor bias
voltage and additional specification.
