Weight
0.6 kg Ideal for measuring esophageal pressure with
air-filled catheter, mouth pressures and transdi-
aphragmatic pressures For use with most research animals
This differential pressure transducer is mainly used for
measuring esophageal pressure using air filled catheter.
It is ideal for use with mouse, hamster, rat, guinea pig,
rabbit, ferret, cat and dog.
This Differential Pressure Transducers is for
very low differential pressure measurements.
They are especially suitable for applications in
plethysmography and pneumotachography.
This Transducer has very small internal vol-
ume and volumetric displacement to achieve
high frequency response. It is highly resistant
to mechanical shock and over-pressure. A
diaphragm of magnetically permeable materi-
al clamped between two symmetrical assem-
blies completes a magnetic circuit with each E-
core. Application of pressure causes
diaphragm deflection, increasing the gap in
the magnetic flux path of one core and
decreasing the gap equally in the other core.
The magnetic reluctance varies with the size of
the gap, changing the inductance ratio. The
inductance ratio is then measured by an
Carrier Frequency bridge amplifier in which
an output voltage proportional to pressure is obtained. The CFBA Amplifier for the
PLUGSYS or a regular bridge amplfier in combination with the Carrier Frequency
Adapter Box on can be used.
All exposed parts of these Transducers are made from 410 stainless steel to prevent
corrosion. They have a 3.1 m (10 ft) cable and are supplied individually with two
pieces of 4.8 mm (0.31 in) ID hose for connection to a Pneumotachometer, see
pages F40 to F41. Interchangeable Replacement Diaphragms are offered separately
to change the Transducers operating pressure range. For very low differential
