This document is the operating manual for the Model 3190 True Mold Angle Device produced by Troxler.
The Troxler Model 3190 True Mold Angle Device (TMA) is an external, passive measuring device designed to provide real-time display of compaction angles for the Model 4140 Gyratory Compactor. It attaches to the frame of the compactor and measures the mold angle externally without interfering with normal operation or limiting sample size.
| Ambient Operating Temperature | 10 to 50°C (50 to 122 °F) |
|---|---|
| Power Requirements | 12 V dc, 500 mA |
| Weight (Unit) | 3.6 kg (8 lb) |
The TMA uses a simple two-point measuring method with a trigonometric function to calculate the true mold angle.
No, it is a passive measuring device that does not affect the mold angle or the relationship between the sample and the ram head.
