Functional Overview
Purpose of Equipment 
The panels are used to control pressure and monitor flow of liquids in and out 
of various testing apparatus. The device can be used with other equipment to
perform these ASTM procedures: D4767, D2850, D5084 and other international
standards. 
How equipment can be used: 
•	 To	back-pressure	saturate	a	specimen.	
•	 Monitor	consolidation	or	swell	(volume	change)	
•	 Control	pressure	and	monitor	volume	change	during	a	shear	test.	
•	 Monitor	flow	in	and	out	of	a	sample	and	control	pressure	for	 
permeability testing.
Description 
Humboldt FlexPanels are available in 5 separate panel configurations, which can 
be grouped together to accommodate from 1 to 5 cell setups. The five different
types of Panels include:
HM-4140.3F— A Master Controller. The Master Control panel can be used
to control the functions of up to 5 cells utilizing combinations
of HM-4150A and HM-4160A FlexPanels. Each cell requires a
group of dedicated control burettes. HM-4150A panels provide
1 group of controls and the HM-4160A panels provide 2 groups
of controls.
HM-4150.3F— 1 group of control burettes and an integral master controller
HM-4160.3F— 2 groups of control burettes and an integral master controller
HM-4140M.3F— Same as HM-4140.3F, except it reads in kPa
HM-4150M.3F— Same as HM-4150.3F, except it reads in kPa
HM-4160M.3F— Same as HM-4160.3F, except it reads in kPa
HM-4150A— Add-on panel with 1 group of control burettes
HM-4160A— Add-on panel with 2 groups of control burettes
