3410 Intrinsically Safe Low Profile Load Cell

3410 Intrinsically Safe Low Profile Load Cell

Specially designed load cells with loop-powered intrinsically safe amplified output for use in oil field and other hazardous locations. These load cells are derived from other proven Interface models by adding high resistance strain gages for low-current loop power and shielded internal amplifier for extra low emissions and minimal EMI susceptibility.

  • Stainless steel construction
  • Sealed connector
  • IP68 environmental protection
  • Internally amplified 4-20 mA output, loop-powered
  • Unipolar (T or C) or bipolar (T and C)
  • Zero and span adjustment access
  • CE certified
  • Explosion protection by Intrinsic Safety per ATEX designation: II 2 G Ex ib IIC T4

Model 3400 family are Intrinsically Safe Load Cell

The Model 3400 is a family of load cells of various mechanical configurations, all with the same internal 4–20 mA loop-powered amplifier and 4000-5000 ohm strain gage bridge. All load cells in the family are intrinsically safe when installed per the installation manual and are certified as such by the following Notified Body:

Physikalisch-Technische Bundesanstalt
Intrinsic Safety is an explosion protection technique that ensures that a circuit operating in an explosive atmosphere cannot cause ignition. This is done by limiting the electrical and thermal energy in the load cell. The 3400 protection is for Zone 1 and the ATEX designation is:
