Introduction
The PASCO Model CI-6534A Low Pressure Sensor
(0-10kPa) is a pressure sensor that is designed to be
used with a PASCO computer interface. This low
pressure sensor is ideally suited for use with the
PASCO Respiration Belt or the PASCO Heat Engine
Apparatus.
CI-6534A Low Pressure Sensor
The low pressure sensor consists of the electronics
box with a cable that has a DIN plug for connecting to
a PASCO computer interface. The pressure sensor
uses a 10 kiloPascal transducer. This type of
transducer has two ports. The reference port of the
transducer is inside the electronics box. It is always
open to the atmosphere and not available to the user.
The other port is connected to the atmosphere via the
pressure port connector at the front of the pressure

sensor unit. It has a "quick-release" style connector for
attaching accessories such as the PASCO CI-6535
Respiration Belt accessory (which includes a Low
Pressure Sensor). The pressure sensor gives a reading
of "zero" when there is no pressure difference between
the internal reference port and the external pressure
port connector.
The transducer is durable, but it is designed to be used
with non corrosive gases such as air, helium, nitrogen,
etc. Do not let the transducer get wet. The maximum
short-term pressure that the sensor can tolerate without
permanent damage is about 100 kPa (14 psi). Please be
careful to not apply high pressure to the sensor.
The electronics box contains a precision operational
amplifier (op amp) that can drive a heavy capacitive

Connect the Pressure Sensor unit to analog channel A, B, or C of the Science Workshop computer interface box using the cable with the DIN connectors (Figure 2). Alternatively, the unit can be plugged directly into the analog channel barb jack.
- Page 4 Respiration Rate Sensor 012-07034A Mounting on an Experimental Apparatus Use the 1/4-20 threaded connector located on the bottom of the sensor box to secure the Pressure Sensor to an experimental apparatus (Figure 5). The alignment hole fits over an alignment pin included on some PASCO apparatuses.

Gay-Lussac’s Law (pressure vs. absolute temperature) Gay-Lussac’s Law states that if the volume remains constant, the pressure of a container of gas is directly proportional to its absolute temperature.
