DIR Digital Load Indicator

DIR Digital Load Indicator

The DIR digital is a basic, easy-to-use, budget-minded load indicator. The DIR model simultaneously displays both live load and rate of load in force units per second during a test and peak load automatically at the end of a test. The DIR is one of the easiest-to-use digitals available, featuring automatic test reset—eliminating the need to zero between tests—and automatic peak-load display at the end of a test through the pre-set sample-break detector function. The digital’s face is set on a 60º angle for easier reading of load values, and the display uses 3/8” (9.5 mm) characters protected by a nonglare, scratch-resistant window. Users can select from load-value engineering units of lbs., kN, kg, and N. Designed for years of dependable service, the digital’s tactile keys have a life cycle of greater than two million uses, and accuracy is ±.5% of indicated load from 1% to 100% of machine capacity, exceeding ASTM C-39 and E-4 requirements. The calibration program is password protected in permanent, non-volatile memory. The DIR digital has no hardcopy test documentation capabilities.

SD Digital Load Indicator

SD Digital Load Indicator

The SD Digital System was designed for production-testing laboratories where dependability, accuracy, and minimal operator input is required. During a test it indicates live load or stress and rate of load simultaneously, and at the end of a test it automatically displays both peak stress and load. Plus, if activated, the average rate of load applied to a specimen during a test can also be displayed. The SD is truly operator-friendly; using menu-driven scroll-through prompts. A pre-set menu lists six common specimen types from which to select: cylinder, cube, beam center or third point, round, and cross-sectional area. All test information is easily read on the indicator’s back-lit LCD display, which can show test data in any of the selectable engineering units, including lbs., kN, N, kg, psi, MPa, Kpa, kg/cm2, in, mm, cm, seconds, or minutes. A durable membrane keypad allows you to scroll, enter, store, print, or enter numbers manually.

Accuracy is achieved through a five-point calibration program using piece wise linear fit between points to exceed ASTM C-39 and E-4 requirements at better than ±.5% of indicated load from 1% to full machine capacity. The linearity of the calibration in specific areas is further improved through a unique edit-calibration program, which allows the on-site calibrator to re-enter the program and reset an individual value assigned to a point. For added dependability, if the digital’s calibration is ever changed or lost, its original calibration can be reinstalled in the field by reentering the original A/D conversion values into the program. Up to four separate calibration programs can be stored in the SD, allowing it to be used with multiple transducer/load cell combinations in one or more load frames.

For hard-copy test documentation, up to 750 tests can be stored in memory and printed directly on an optional serial-port printer or transferred to a PC through an RS-232 serial port. The print function allows the operator to print only the current test or all stored tests at once. The standard test report uses a spreadsheet format and lists sequential test number, date and time, specimen ID number, specimen type, specimen area and length, peak load and stress, cylinder correction factor, and cylinder break type. Optional information includes average rate of load applied to a test specimen, specimen age and weight, job ID number, and a statistical summary of peak load and stress.

LXI Digital Load Indicator

LXI Digital Load Indicator

The LXI Digital System is the system of choice for commercial and in-house testing laboratories where ease of operation, accuracy, and test documentation are required. During a test it displays load, stress, rate of loading in load or stress units seconds or minutes, plus the type of specimen being tested and its size - all simultaneously on the indicator’s four-line display. At the end of a test it automatically displays peak stress and load, and, if activated, the average rate of load applied to the specimen during the test, with an accuracy exceeding ASTM C39 and E4 requirements. The LXI’s user-friendly scroll-through test set-up menu allows the operator to select an option and enter a “yes/no” command to activate or a numeric value to set the test parameter field. A pre-set menu lists seven common specimen types to select from: cylinder, cube, beam center, beam third point, and cross-sectional area, allowing you to select, display, and document test data. All test information is easily read on the indicator’s back-lit LCD display, which can show test data in any of the selectable engineering units, including lbs., kN, N, kg, psi, MPa, Kpa, kg/cm2, in, mm, cm, seconds, or minutes. A durable membrane keypad allows you to scroll, enter, store, print, or enter numeric values. Calibration is also password-protected.

Accuracy is achieved through a 10-point calibration program using piece wise linear fit between points to exceed ASTM C39 and E4 requirements at better than +.5% of indicated load from 1% to full machine capacity. The linearity of the calibration curve in specific areas is further improved through a unique edit calibration function, which allows the on-site calibrator to re-enter the program and reset an individual value assigned to a calibration point. The indicator can also be used with multiple transducer/load cell combinations with one or more load frames by storing up to six separate calibration programs. For added dependability, the LXI features a unique restore calibration program that allows the calibration to be re-installed in the field if it is ever changed, lost, or the unit is damaged. Simply enter the original load value points and their corresponding A/D counts into the calibration program via the digital keypad. Your machine’s original calibration information is maintained in the unit’s Q.C. inspection report. For hard-copy test documentation, up to 1,000 tests can be stored in memory and printed directly on a parallel-port printer or transferred to a PC through a standard RS-232 serial port. The system also features the X-Y plotting of a load or stress vs. time graph with title block listing date and time, specimen ID number, and peak stress of the test. An optional compatible printer is required for graphing.

The standard test report printout is in a spreadsheet format and lists the following information: sequential test number, date and time, specimen ID number, specimen type, specimen area and length, peak load, and peak stress. Optional data includes average rate of load applied to a specimen during a test, cylinder correction factor to C-39, cylinder break type, cylinder cap type, specimen age and weight, operator ID number, and statistical summary of peak load and stress. Print options allow you to print only the current test or all stored tests and X-Y graphs.
