Instruction Manual 012-11726A ® *012-11726* Hydraulics Structures Set ME-6984
The cover page shows the ME-6984 Hydraulics Structures model of a hydraulic boom. Pressurized fluid moves from the syringe to the hydraulic cylinder. As the piston moves out of the cylinder, it lifts the boom structure.

Model No. ME-6984 Theory Theory Hydraulics is a topic in applied science and engineering that deals with the mechanical properties of liquids. Pneumatics is a topic that deals with the study and application of the use of pressurized gas to affect mechanical motion. Blaise Pascal described the behavior of a fluid (gas or liquid) in a closed container. Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container.
Hydraulics Structures Set Operation Couplers Pressure Sensor Coupler The pressure sensor coupler has a “T” shape. The shorter arms of the “T” have a male luer lock at one end and a female luer lock at the other. The longer arm of the “T” has an inline quick connector at the end for connecting to the pressure port on a pressure sensor. Push the inline quick connector onto the pressure port, and turn the quick connector clockwise (left to right) until the connector locks in place.
Model No. ME-6984 Operation the piston of the smaller syringe than it is to push on the piston of the larger syringe.
Hydraulics Structures Set Adding Load Cells Using a Liquid Instead of a Gas Fill a syringe with a liquid. Connect the syringe to the syringe coupler. Push the piston slowly to force liquid from the syringe into the syringe coupler until all the air is pushed out of the coupler. Finally, connect a second syringe (or the hydraulic cylinder) with the piston all the way in to the liquid filled syringe coupler.

Hydraulics Structures Set Ideal Gas Law Introduction The Ideal Gas Law Apparatus, TD-8596A, allows simultaneous measurements of temperature and pressure of a gas as it is compressed. A low thermal mass thermistor is built into the base of the syringe to measure temperature changes inside the syringe. The response time is around 0.5 second. The plunger is equipped with a mechanical stop that protects the thermistor, and also allows for a predetermined change in volume.
Model No. ME-6984 Ideal Gas Law Procedure Set the plunger for a volume of 40 cubic centimeters (cc). Hold the base of the IGL Apparatus firmly against a sturdy horizontal surface. Ideal Gas Law Apparatus TD-8596A Pressure Sensor Coupler sidearm Temperature Connector plug Syringe Coupler Pressure/Temperature Sensor PS-2146 To PASport Interface PASport Extension Cable PS-2500 Slap down on the plunger with the palm of your hand to fully compress the gas inside the syringe.
