AVONGARD - TP11 Plus Tell-tale
Avongard Plus Tell-Tales can be used to monitor horizontal or vertical movement across a crack on a flat surface. The Plus offers two upgrades to the standard design. Rather than presetting the two measuring plates together at zero with tape, the plus uses four small pegs, which ensure alignment during installation and then removed during monitoring. The plus also provides measuring flats, which allow accurate readings to be taken with calipers during monitoring.
Application: Monitoring of crack displacement on concrete or walled structures.
Range: ± 25 mm horizontal and ± 10 mm vertical.
Accuracy: ±1.0 mm on the scale, or to an accuracy of ±0.1 mm with calipers
Temperature: -40 to +80 degrees C.
The coefficient of thermal expansion is 6.8 x 10-5 cm/cm per degree C.
