Strain Gauge Transmitter
The Hardy HI 2204LT transmitter 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.”
Notice for Non RoHS Compliant Construction
The transmitter produces a current limited, 5 VDC excitation voltage that 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.
Hardy’s process weighing solutions are easy to install, configure, commission, and operate. They are easy to maintain and save you time, money, raw materials, and/or finished product. Contact us today to integrate weight into your application!
