Standard Universal Testing Machines / inspekt mini:

inspekt mini, 3 kN with peeling device

Load frames

The universal testing machine inspekt mini is available with load frames of 3 kN and 5 kN. The frame arms are driven by DC motor via a play-free pre-stressed ball race spindle.

The driving spindle is protected against fouling by bellows. Optionally, the speed range can be extended up to 2,000 mm/min and the arm lift can be extended to 1,100 mm.

inspekt mini with LT1

Force measurement

Force measurement is conducted by a strain gauge dynamometer.

The measurement electronics provide Class 1 (optionally Class 0.5) accuracy acc. to DIN EN ISO 7500 in the range between 0.8 and 100 % nominal load. All load cells are equipped with sensor plugs guaranteeing the automatic recognition of adjustment and calibration parameters.

Measurement and Control System

All elements of voltage supply as well as machine and motor control of the inspekt mini series are arranged in a desktop unit.Machine control and synchronous data collection are provided by a digital controller.The connection to the computer and application software is implemented through the RS232 user interface.

The machines can be operated either with PC or as standalone version for simple testing jobs. The controller has ports for additional data collection cards. The basic version is delivered with force and distance measurement channels. For the standalone version, the measured data are represented by a standard PC printer directly connected to the electronics, and the digital force-distance display.
