ATEX Embedded Load Cell Amplifier, Strain Gauge Signal Conditioner (ICA5ATEX)

ATEX Intrinsically Safe
ICA5ATEX 4-20mA 2 wire

The ATEX miniature load cell signal conditioner offers a high performance strain gauge amplifier in miniature format, designed specifically for fitting inside load cells, converting a standard load cell to a mA output.

Offering high stability and fast response.

Optional (ILE) in line enclosure to convert a standard load cell to a conditioned load cell output

  • ATEX certificated strain gauge conditioner and load cell amplifier
  • Miniature PCB format for fitting inside sensors, 19mm diameter, 7.6mm height
  • 2 wire current loop 4-20mA output
  • Low interaction between the trimmers makes calibration fast and easy
  • High speed 1000 Hz
  • User selectable span and zero resistors
  • Robust design, high noise immunity & reverse polarity protected

FR=Full Range (16mA)Note 1: 1000 Ohm load cell – Typically 0.53V for 350 Ohm cell
Note 2: Set by calibration resistor
Note 3: Limited by the 300Ω barrier impedance
Note 4: 1000 Ohms load cell – change R1 to suit other load cell impedances.Note: Recommended bridge impedance is 1,000 OhmsNote: The voltage between either of the power supply connections and the load cell shield should not exceed 50V. Any leakage will be greater than 10M Ohms.
