ワイヤレスデータ収録システム ワイヤレスコントローラ ZT-120

Wireless Data Recording System Wireless Controller ZT-120

The wireless data recording system consists of the wireless module ZT-014 and the wireless controller ZT-120.
The wireless module incorporates an A/D converter that converts measurement data from strain gage transducers into digital data for interval measurement, data recording, and monitoring. Since wiring from the sensor to the controller can be made wireless, it is ideal for measurement in locations where wiring of measurement cables is difficult or detracts from the landscape, or for measurement of moving objects, reducing wiring labor and costs.
Measurement data is stored in the memory of the wireless module, and the wireless controller and PC are brought in periodically to collect the data.

Insertion inclinometer management

Insertion-type inclinometer management software IMP-7210

IMP-7210 is the software for data processing of the measurement data of insertion inclinometers.
The software imports via RS-232C the insertion inclinometer measurement data measured using a measuring instrument (TC-32K/TC-31K) and stored in the data memory, and uses the data to determine the sectional and cumulative displacement of the insertion inclinometer at each depth and outputs graphs such as contrast and distribution diagrams and lists of data.
The measured data of the insertion inclinometer can also be input manually and directly.

Features
  • Observation hole numbers (hereafter referred to as hole numbers) can be set up to 99.
  • Compatible with the incremental, normal and multi-channel modes of the measuring instrument (TC-32K/TC-31K).
  • Measurement data stored on the memory card of the measuring instrument (TC-32K/TC-31K/TC-31M) can be read directly by a PC for data processing.
  • Initial value data can be arbitrarily selected from the measurement data.
  • Data from daily rainfall and water level gauges can be input, and can be contrasted and graphed with the measured data of the insertion-type inclinometer.
  • The contrast chart, change over time chart, distribution chart and numerical table can be printed.
