Description
The PASCO Model PS-2151 Thermocline Sensor
allows students to study the relationship between
depth and temperature in a body of water.
The sensor head has two sensors built into a
watertight housing: a depth sensor and a tempera-
ture sensor. It has a 10 m cable with a connector
that plugs into the amplifier box. The amplifier
box, in turn, plugs into your PASPORT interface.
The depth sensor is a
gauge-type pressure sen-
sor with a stainless steel
housing and a stainless
steel diaphragm. The
entire sensor head is
designed to resist the
corrosive effects of salt
water.
Operation
Connect the Thermocline Sensor head to the
amplifier box. Connect the amplifier box to a
PASPORT interface. If you will use a computer to
collect data, connect the interface to the computer
and start DataStudio.
Start data recording and lower the sensor head
into the water. The temperature sensor takes a few
seconds to respond to changes in temperature, so
lower the sensor head slowly. For the most accu-
