SA-20P Auxanometer
Overview
The SA-20P Auxanometer is a draw thread displacement transducer. Installation simply involves bolting down the housing and then attaching the draw thread to the part, which is to be measured. The output of the SA-20 Auxanometer is proportional to the amount of thread pulled out of the unit. The thread is a plastic stretch-resistant cord and is tensioned by an internal spring pack giving the unit, amongst others, the ability to adjust the tension. The output of the SA-20 Auxanometer is Voltage.
Standard output cable length is 4 meters.
Specifications
| Measurement (draw thread) range | 0 to 2 m |
| Resolution | 2 mm |
| A thread is ended with a ring for connecting an extension wire (thread, cord, clip) provided by a user. | |
| Protection index | IP 53 |
| The mechanical analog display, located on the front panel, allows estimating approximately a current readout of the unit. | |
| The tension of the thread has two switchable levels, equivalent to 30 g and 50 g counterweight, approximately. | |
| A thread outlet is located at the bottom panel of the housing. A guide wheel and a lug provide the upward thread direction. | |
| Mounted on a trunk or other base with the use of two screws or bandings (not included into delivery set). | |
