Bailey & Mackey pressure transducers
are divided into two groups each being based on a
different measuring technology.
The first group are:
Piezo-Resistive Transducers which use the
voltage that is generated when a semi-conductor
beam is deflected by an applied pressure, this
voltage is then amplified which in turn gives a voltage
or milli-amp output.
These devices give greater accuracies than the
Hall Effect devices and we manufacture this type of
transducer from ±0.1% to ±0.5% depending on the
application.
The second group are:
Hall Effect Transducers which uses a magnet
and a flux strength device to measure the deflection
of a diaphragm under pressure and give an analogue
signal to an amplifier which in turn gives a voltage or
milli-amp output.
These devices are low cost and have a similar
accuracy to a pressure gauge.
Both types of transducer outlined above have CE
marked versions to EN 50081 & EN 50082 for EMC
emission and immunity.
Corrosion resistant materials are available for both
70PT
the Hall Effect and the Piezo-resistive types to enable
them to be used on most fluids.
Bailey & Mackey Transducers can be
modified to make them more suitable for the 69PT
application on which they are to be used, please
contact our sales office for further assistance.
No maintenance is required with the pressure
transducers in this catalogue but periodic calibration
checks should be made and any re-calibration
adjustments made to ensure optimum performance.
A range of instruments calibrated to correspond with
the pressure transducers are also illustrated in this
catalogue.

Pressure Transducers Installation and Use Pressure Transducers Installation and Use
A Pressure Transducer correctly installed and to the correct
specification gives an electrical output proportional to the
pressure in the system which helps to ensure the safe working
of process plant and machinery.
a)
Before fitting the pressure transducer to a pressure source
check that the range (full scale) of the device is the same or
higher than the pressure to be applied.
b)
Before fitting the pressure transducer to a pressure source
check that the wetted parts are compatible with the fluid being
used, and that the pressure connection correctly matches that
of the pipework.
c)
When fitting the pressure transducer to pipework use correct
sealing methods. Do not use the transducer body to tighten
the pressure transducer to the pipework, use correct spanners
on the hexagon base.
d)
Do not use pressure transducers on Oxygen or Acetylene
unless approved by our Technical Department.
e)
Ambient and process temperature acting on the transducer
should be within catalogue values. The unit should be
protected from higher fluid temperatures by means of a
syphon tube filled with condensate before use. The fluid in
the pressure chamber should not be allowed to freeze or
crystallise as this will lead to rupture of the sensing element.
f)
Differential pressure transducers should not be used with
more than the range of the transducer applied to one side
unless approved by our Technical Department. Line pressure
must not exceed the line pressure stated on the pressure
transducers label. The higher of the two pressures must be
connected to the port marked high and the lower of the two
pressures must be connected to the port marked low.
g)
Ensure that the pressure transducer is connected electrically
in accordance with the installation instructions supplied
with the unit. Incorrect connection can damage the pressure
transducer beyond repair.
If in doubt concerning the application of any pressure transducer please contact
our Technical Department who will be only too pleased to give you advice.

Bailey & Mackey pressure transducers
are divided into two groups each being based on a
different measuring technology.
The first group are:
Piezo-Resistive Transducers which use the
voltage that is generated when a semi-conductor
beam is deflected by an applied pressure, this
voltage is then amplified which in turn gives a voltage
or milli-amp output.
These devices give greater accuracies than the
Hall Effect devices and we manufacture this type of
transducer from ±0.1% to ±0.5% depending on the
application.
The second group are:
Hall Effect Transducers which uses a magnet
and a flux strength device to measure the deflection
of a diaphragm under pressure and give an analogue
signal to an amplifier which in turn gives a voltage or
milli-amp output.
These devices are low cost and have a similar
accuracy to a pressure gauge.
Both types of transducer outlined above have CE
marked versions to EN 50081 & EN 50082 for EMC
emission and immunity.
Corrosion resistant materials are available for both
70PT
the Hall Effect and the Piezo-resistive types to enable
them to be used on most fluids.
Bailey & Mackey Transducers can be
modified to make them more suitable for the 69PT
application on which they are to be used, please
contact our sales office for further assistance.
No maintenance is required with the pressure
transducers in this catalogue but periodic calibration
checks should be made and any re-calibration
adjustments made to ensure optimum performance.
A range of instruments calibrated to correspond with
the pressure transducers are also illustrated in this
catalogue.

Pressure Transducers Installation and Use Pressure Transducers Installation and Use
A Pressure Transducer correctly installed and to the correct
specification gives an electrical output proportional to the
pressure in the system which helps to ensure the safe working
of process plant and machinery.
a)
Before fitting the pressure transducer to a pressure source
check that the range (full scale) of the device is the same or
higher than the pressure to be applied.
b)
Before fitting the pressure transducer to a pressure source
check that the wetted parts are compatible with the fluid being
used, and that the pressure connection correctly matches that
of the pipework.
c)
When fitting the pressure transducer to pipework use correct
sealing methods. Do not use the transducer body to tighten
the pressure transducer to the pipework, use correct spanners
on the hexagon base.
d)
Do not use pressure transducers on Oxygen or Acetylene
unless approved by our Technical Department.
e)
Ambient and process temperature acting on the transducer
should be within catalogue values. The unit should be
protected from higher fluid temperatures by means of a
syphon tube filled with condensate before use. The fluid in
the pressure chamber should not be allowed to freeze or
crystallise as this will lead to rupture of the sensing element.
f)
Differential pressure transducers should not be used with
more than the range of the transducer applied to one side
unless approved by our Technical Department. Line pressure
must not exceed the line pressure stated on the pressure
transducers label. The higher of the two pressures must be
connected to the port marked high and the lower of the two
pressures must be connected to the port marked low.
g)
Ensure that the pressure transducer is connected electrically
in accordance with the installation instructions supplied
with the unit. Incorrect connection can damage the pressure
transducer beyond repair.
If in doubt concerning the application of any pressure transducer please contact
our Technical Department who will be only too pleased to give you advice.

Pressure transducers are divided into two groups based on different measuring
technologies.
1 - Piezo-Resistive Transducers which use the voltage that is generated when a
semi-conductor beam is deflected by an applied pressure, this voltage is then
amplified which in turn gives a voltag or milli-amp output. These devices give
greater accuracies than the Hall Effect devices.
2 - Hall Effect Transducers use a magnet and a flux strength device to measure the
deflection of a diaphragm under pressure and give an analogue signal to an
amplifier which in turn gives a voltage or milli-amp output. These devices are
lower cost and have a similar accuracy to a pressure gauge.
