Digital Specialist Flexure Gauge, DU

Flexures are ideal for very high volume and high precision applications such as bearing component gauging. they are often the best solution for measuring moving material, such as roundness testing, with Orbit set to very high resolution and fast data transmission.

Digital Flexure (DU) - Specification

Digital Flexure
Measurement Performance	DU/1	DU/2
Mechanical Travel (mm)	1.7	2.5
Measurement Range (mm)	1.0	2.0
Repeatability¹	<0.1 µm
Resolution (user selectable)	<0.1 µm
Accuracy (% of reading)²	0.1
Tip Force (Spring Push) (horizontal attitude ±20%)	1.5 N at mid position
Tip Force (Pneumatic) (horizontal attitude ±20%)	1.0 N at mid position at 2 bar
Temperature Coefficient	<0.01% % FS/ºC
Overtravel (mm)	0.1	0.1

¹See Zonal Repeatablilty Specification for off center repeatability.
²Accuracy 0.1 µm or % reading, whichever greater. Accuracy assumes tip holder <20 mm and mounted on center. Spring operation with 1.5 N tip force.

Mechanical Specification
Flexure Material	Aluminium and Steel
Mass (including tool holder, 20 mm tip holder and ball tip) excluding PIE/Cable (g)	<60	<70
Mass of Tool Holder (g)	12
Gaiter Material	High Grade Polymer
Cable Length / Type	2 m / PUR
Operating Life (dependant on application)	>20 million cycles
Pneumatic Operating Pressure³	1.5 bar to 2.5 bar relative

³For best gauging results it is recommended that the flexure is operated so that the spring provides the gauging force and the pneumatic cylinder is used to retract the flexure.
