Description

TD-700T is a digital indicator to measure and display physical quantity such as load, pressure, and torque working with strain gauge transducers. Colour graphic LCD display, high-speed sampling, TEDS function (IEEE1451.4 class 2 mix mode interface compliance) and various hold function, the various functions are condensed in a DIN half-size body.

  • High-performance colour graphic LCD screen
  • DIN size body, compact and lightweight
  • TEDS – plug and play
  • 4000 times / second (20000 times / sec at hold) high-speed processing

Product Features

Display options

Switchable display

Switchable between the 5-digit digital display that enables direct reading of physical quantities up to ±99999 and the bar meter display that shows an analogue representation of the indicator value.

Positive and negative value sample hold

TD-700T can sample, hold and average both positive and negative values. It can be used in measurements using dual pole devices such as torque sensors.

Static strain display

Allows the measurement of static strain. This function makes it easier to check load-cells for deterioration and plastic deformation.  

Comparison function

It is possible to set up to 4 values (HHI, HI, LO and LLO) to compare with the input signal. The definition of those values is changeable (e.g. 3 upper limits and 1 lower limit). This provides users with a wide variety of applications, and would help avoid damages and/or problems on your products.

Analogue voltage / current output (isolated)

TD-700T can also be used as a signal conditioner.
