LT802 Rolling Force Display Controller
◆ Introduction
LT802 applies to resistor strain type sensor, which is specially designed for rolling force measurement, pressure or tension test, with more functions than previous force measurement instrument. In the LT802 uses many advanced techniques to eliminate the effect of temperature drift and time drift. Unique automatic calibration and nonlinear correction function in site of the force-measuring system. With fully digital debugging, it makes your work easier, and it is a very high ratio of performance to price force measuring instrument.
Features:
·Applies to resistor strain type sensor
·Can be connected with two independent sensors ( A&B) and calibrate separately.
·3 display windows show A、B、A+B or︱A-B︱
·The Σ-△ conversion, strong disturbance resistance
·Multilevel digital filter, adapted to different needs of field
·Full digital debugging and operation
·Two calibration methods: weight calibration or automatic calibration
(Automatic calibration is very useful for the elusive field calibration places)
· Optional as many as 12 point calibration method, easy realizes the nonlinear correction function in force measuring systems
·With a peak hold function
·The instrument has the number recognition function, convenient system networking
·With self-locking function, to prevent operation by mistake
·Easy to use, 7 buttons complete all operations
·Optional four 4~20mA analog output, a RS232C or RS485 serial port, five alarm control contact output, with sound and light alarm function
