Item Component
Description
4
Load Frame
Control
Module
Contains the crosshead lift controls as well as the
Emergency Stop
switch.
5
Grip Control
Module
Contains hydraulic pressure gages as well as controls to clamp and unclamp
hydraulic grips.
6
Hydraulic
Crosshead
Locks
Clamps the crosshead to the columns. (Optional)
7
Force Sensor
(Load Cell)
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.
8
Actuator
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).
9
Servovalve
Controls the rate and direction of hydraulic fluid to the actuator.
10
Hydraulic
Service
Manifold
(HSM)
Controls the application and removal of hydraulic pressure to the load unit.
11
Accumulators
Improves the actuator's response and reduces hydraulic line fluctuations.
One accumulator connects to the pressure line, and the other to the return
line.
12
Displacement
Sensor
(LVDT)
Measures the position of the actuator. The sensor is mounted inside the
actuator.
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.
