3400 Intrinsically Safe Load Cells

Why the Interface series 3400 Intrinsically Safe Load Cells is the best in class: • 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 (approval pending) per ATEX Zone 1 designation: II 2 G Ex ib IIC T4

The 3400 Series are a specially designed versions of Interface 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.

ATEX approval requires a stainless steel housing and a sealed design such as our IP68, so many standard Interface models qualify with only slight factory modification. Many of the types of load cells available are listed below and can can be ordered customized to match customer application requirements. Please contact the factory for specific information.

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.

The Interface line of Intrinsically Safe products consists of the following models:

• 3400 Tension and Compression Low Profile load cell,
• 3400 Compression Only Low Profile load cell,
• 
  Tension-Compression Column Type load cell,
• 
  Model 3461 and 3462 Load Pins,
• 
  3401 Compression Beam,
• 3403 Tension Link

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
Braunschweig, Germany

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: II 2 G Ex ib IIC T4

Specific Models 3401 through 3499 are unique in being constructed in accordance with the certified circuit. Configurations for mechanical connections and force capacities are created to fit individual applications. The following are representative of specific models.
