11. PC 1750 Transducer
PC 1750 T
RANSDUCER
transducers and pressure amplifiers to measure
different gas pressures in the breathing system.
There are two versions of PC 1750 T
• PC 1750A and B with four pressure transducers
mounted on the PC board. In case of pressure
transducer failure, the complete PC 1750 must be
replaced.
• PC 1750C (or later) with four PC 1781 P
T connected to PC 1750. In case of
RANSDUCER
pressure transducer failure, the concerned PC 1781
can be replaced.

The four pressure transducers are connected to the
breathing system with internal tubings. The following
gas pressures are measured:
1. Expiratory pressure (EXP)
2. Inspiratory pressure (INSP)
3. PEEP pressure (PEEP)
4. Manual breathing bag pressure (MAN).

• Expiratory flow transducer
• Bellows position sensor.
As the gas in the breathing system may be
contaminated, the pressure transducers must be
protected with filters. The PEEP pressure transducer
filter is mounted on the internal tube and connected
onto the transducer. The other three filters are
mounted into the silicone muff in the patient
cassette docking station, see illustration below.
All four filters must be replaced during the "Six
months maintenance" and the "Twelve months
maintenance".

the concentration knob on the vaporizer. The
mechanical interlocking system makes it impossible
for more than one vaporizer to be active at a time.
There are two connection nipples for each vaporizer:
• One outlet nipple for fresh gas to the vaporizer.
• One inlet nipple for fresh gas from the vaporizer.
There is a one-way valve (OV9 – OV11) in each one
of the inlet nipples.
The following parts in the vaporizer magazine must
be replaced during the "Twelve months
maintenance":
• Two O-rings on the hub inside the vaporizer
magazine.
• One-way valve and O-ring inside each inlet nipple.
• O-ring on each inlet and outlet nipple (seals
towards the vaporizers).
