The FT20 and FT50 force transducers are designed for measurement applications in animal experimental research or other technical uses in general laboratory, light industrial or office environments. The FT20 has a maximal load of ± 20 cN (~20 g force) and the FT50 has a maximal load of ± 50 cN (~50 g force).

The installed sensor system is based on a resistance full bridge circuit, which can be directly connected to any HA-HSE bridge amplifier, e.g. the PLUGSYS TAM amplifier module. If using other DC bridge amplifiers, e.g. Grass or Gould, there are different connection cables available.

Key Features

  •  Isometric (low displacement of the measurement cell)
  • Can be used in both directions, pull or push
  • Two ranges available +/-20 g, and +/-50 g full scale (FS) 
  • Suitable for small muscle and tissue samples like papillary muscle, Purkinje fibers and vessel rings
  • Resistance full bridge circuit (Wheatstone bridge) can be used with most commonly used DC bridge amplifiers
  • Supply voltage range 5 to 10 VDC (max. 15 mA
  • Removable connection cable with 6-pin binder connector for HA-HSE bridge amps or additionally available special cables for products from other manufacturers, e.g. Grass or Gould.
  • Removable holder with two M5 fastening threads for horizontal or vertical rod mounting
  • Compact design, two mechanical end stops as overload protection and additional front

Included Items

  • Force transducer FT20 or FT50
  • Removable holder with 8 mm mounting rod
  • Standard connection cable
  • Small spring attachment hook
  • Test weight 1 cN (~1 g)
  • Hexagon screwdriver 2.5 mm
  • User’s manual
  • Storage box
