HI 2204 Weight Transmitter

Strain Gauge Transmitter

The Hardy HI 2204LT comes sealed and potted to withstand typical industrial environments. It has a course zero offset adjustment to remove dead load, a fine zero adjustment to compensate for small differences between load cells/ points, and a span adjustment to set the operating range for the “live load.”

The transmitter produces a current limited, 5 VDC excitation voltage which powers the load cell/point momentarily at the rate of about 90 times per second and converts the signal read into a 4-20 mA output. The transmitter is used primarily in level by weight and force measurement applications.

The HI 2204LT is capable of developing its full 4-20 mA signal while requiring a "live load" of only 33% of the total load cell capacity. This is true even when four 3 mV/V, 350 ohm load cells/points are used.

The transmitter is available mounted in either an optional NEMA 4 rated painted steel (-A3) or NEMA 4X rated stainless steel (-A5) summing junction box for multiple load cell systems.

An intrinsic barrier assembly model HI 705IBA is available for using the HI 2204LT transmitter in a safe environment with the systems load cells in a hazardous rated environment.
