CATEGORY > Extensometers + Compressometers

TELL-TALE CRACK MONITORS

DESCRIPTION

Tell-Tales consist of two plates which overlap for part of their length. One plate is calibrated in millimeters and the overlapping plate is transparent and marked with a hairline cursor. As the crack width opens or closes, one plate moves relative to the other. The relationship of the cursor to the scale represents the amount of movement occurring. Range ±20 mm – Resolution 1 mm. The tell-tales are fixed with screws and adhesive across the crack to be monitored.

Standard Tell-Tale

The Standard Tell-Tale is produced in durable acrylic plastic and is used for monitoring movement across cracks in vertical and horizontal directions on flat surfaces. Coefficient of thermal expansion: 7x10-5cm/cm/°C.

Corner Tell-Tale Plus

The Corner Tell-Tale Plus is produced in polycarbonate and can be used for monitoring movement across cracks in internal and external corners. The TELL-TALE is hinged for use with interntal corners ranging from 70°- 180°. When used in pairs three dimensional movement can be monitored. Coefficient of thermal expansion: 7x10-5cm/cm/°C.

Displacement Tell-Tale Plus

The Displacement Tell-Tale Plus is produced in PVC rigid sheet and is used for monitoring movement across cracks when one surface moves out of plane with the other. The TELL-TALE monitors out of plane movement. Coefficient of thermal expansion: 7.3x10-5 cm/cm/°C.

Tell-Tale Plus

The Tell-Tale ‘Plus’ offers a weather resistant design that monitors the opening or closing of a crack to an accuracy of 1.0 mm, or to an accuracy of ±0.1 mm with calipers. Monitor vertical and horizontal movement with supplied crack record sheets. Also offers increased horizontal monitoring range to ±25 mm and manufactured in vandal resistant polycarbonate. Fixing slots and “extra grip” surface improves screw and adhesive fixings.
