T-TEST K12

What it does

This unit integrates with a PC to acquire, display, and record real-time data from monitored tests conducted in the field using displacement, pressure, or load sensors.

Strengths

1. Low cost
2. High precision
3. Practical and portable enclosure
4. Maximum acquisition frequency of 2 Hz
5. Optional wireless communication system between unit and PC

Description

Operates on a rechargeable internal 6V battery (can also be used in buffer mode if connected to the mains). Connection to the PC is via a USB cable (included).

The unit is housed in a reinforced IP67 enclosure, easy to transport, with a minimum sampling frequency of 2 Hz and 16-bit resolution.

Can connect to:

12 displacement (or deformation, inclination, pressure, etc.) potentiometric or other
technology sensors with an analog voltage output of 0-2.5V or 0-5V or with a current
output of 4-20mA;

1 load cell
(if using a mechanical or motorized load application system) or pressure transducer or other type with a current output of 4-20mA;

1 NTC temperature sensor for ambient temperature or another type of sensor using the included 4-20mA adapter.

The included T-TEST software manages load tests (on structures like floors, piles, trusses, etc.) and other types of inspection tests.
The software acquires data from connected sensors, provides real-time visualization, and records data for later processing. If the load sensor is not connected, the software allows manual entry of the applied load value. The K12 software complements this by graphing “Force-Displacement,” “Pressure-Flow,” etc., and handles real-time zooming and exporting graphs as PNG images.
