PF80

Wire crack meter with datalogger

Turning displacement into measurable data over time
PF80 detects and records every change.

PF80 is a wire crack meter with an integrated, independently operating datalogger for the acquisition and storage of displacement and ambient temperature values.
It allows the monitoring of movements in cracks and joints and the measurement of linear displacements.

Two versions are available for measurement download and configuration via graphical interface and software:
• PF80-WIRELESS – wireless connection to PC
• PF80-USB – Mini-USB connection to PC

KEY BENEFITS
	80 mm stroke
	Extendable cable
	Displacement & temperature
	Integrated datalogger
	Battery powered
	Data download
	Easy installation & low visual impact

APPLICATION FIELDS
	Bridges & viaducts
	Buildings & masonry
	Joints
	Crack patterns
	Linear displacements

OPERATION
The PF80 converts linear displacement into a change in the angular position of a rotary potentiometer. The stainless steel wire, wound around a drum, extends or retracts following the movement of the structure.
	1. Wire drum
	2. Stainless steel wire
	3. Rotary potentiometer

DATA MANAGEMENT
		Data Checker Quick display of displacement and temperature graphs
		Formato CSV - Format CSV File compatibili con comuni software di analisi

Intuitive software. Easy configuration. Data ready for analysis.
The software allows acquisition settings to be configured, measurements to be downloaded, displacement and temperature data to be viewed.

Acquired data can be analysed and displayed graphically for a quick assessment of trends over time.
