3416 & 3430 Coil Tubing Load Cells

3416 & 3430 Coil Tubing Load Cells

These are designed for measuring tension and compression on coil tubing in the oil industry.

  • Hermetically sealed cell
  • Performance to 0.05%
  • 4-20 mA
  • ATEX approved

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.

Model 3400 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:
