Description Component Item
Contains the crosshead lift controls as well as the Emergency
Stop switch. Load Frame Control Module 4
Contains hydraulic pressure gages as well as controls to clamp
and unclamp hydraulic grips. Grip Control Module 5
Clamps the crosshead to the columns. (Optional) Hydraulic Crosshead Locks 6
Sends a signal proportional to the forces being applied to it back
to the interface PC via the controller. The load cell shown
measures both tensile and compressive forces. Force Sensor (Load Cell) 7
Applies forces to specimens. A linear actuator is shown. It applies
compressive and tensile forces. Other types of actuators are
available (such as rotary actuators). Actuator 8
Controls the rate and direction of hydraulic fluid to the actuator. Servovalve 9
Controls the application and removal of hydraulic pressure to
the load unit. Hydraulic Service Manifold
(HSM) 10
Improves the actuator's response and reduces hydraulic line
fluctuations. One accumulator connects to the pressure line, and
the other to the return line. Accumulators 11
Measures the position of the actuator. The sensor is mounted
inside the actuator. Displacement Sensor (LVDT) 12
Load Frame Controls Overview
Control Panel
The controls for the Series 370 Load Unit are located on a module mounted to the front of the load unit.
The following control panel is shown with all available options. The control panel on your load unit might
not have all of these controls depending on your specific configuration.
