Prime USA Scales offers our OP-916 floor scale in a variety of sizes from 2’x2′ up to 7’x7′. Our floor scale features a variety of capacities from 1,000 lb up to 10,000 lb. This unique model offers our 4-20ma output relay indicator for batching applications. Setting target weights to fill bags, drums, feed, and many other uses.

The OP-900R1-12 relay indicator allows for target weight and relay functions. When a setpoint (target weight) is programmed into the digital indicator it will send an alarm to notify a user when the target weight has been reached. The indicator can also send electrical output signals to be used with relays to control the filling device. This will help to improve accuracy, target weight, and provide the user with repeatability. In many applications there may be multiple ingredients being dispensed into containers, drums, or sacks. Additional setpoints (target weights) can be used for each ingredient to produce a final batch.
