Studying Chemical Reactions by Monitoring

Pressure

Many chemical reactions produce gases that can cause

an increase in pressure in a sealed container. The

pressure change can be used to monitor the rate of the

reaction.

Other

PASCO scientific also produces an Absolute Pressure

Sensor (Model CI-6532A), a Differential Pressure

Sensor (Model CI-6533) and a Barometer (Model CI-

6531A). The Absolute Pressure Sensor has a range

from 0 to 700 kiloPascals. The Differential Pressure

Sensor is similar to the CI-6532A, except that both

ports of the transducer are open to the atmosphere. It

is designed for experiments where pressure differs

from one part of the apparatus to another, such as in a

Venturi tube or for a demonstration of Bernoulli’s

principle. The Barometer has a range from 800 to

1100 milliBar (24 to 32 inches of mercury). It is

designed to be a reliable, accurate pressure sensor

for weather studies. It is temperature compensated

and has a voltage regulator, so changes in

temperature or changes in the computer’s power

supply will not interfere with the data.
