HP62 Hopper weight controller

Hopper weight controller with entry for load cells* (digital amplifier at 65.500 points, integrated on board), litres counter for water calculation*, daily start clock*, sensor maximum charge of distribution's line*.

HP62/WHP62 doses the programmed quantity of feed to distribute with resolution to Hectogram and in the meantime it realizes the following functions:

- it verifies that during the distribution the feed increases in the hopper (stopping the distribution and signalling the alarm if a non-decrease of the weight occurs due to effect “bridge” of the feed in the silo);
- it verifies that the distribution of the programmed quantity of feed happens in a prefixed time (stopping the distribution and signalling the alarm if an overcoming of maximum time occurs);
- it verifies that the quantity of feed that is present in the silo doesn't fall under the prefixed quantity of “minimum supply” (signalling with the alarm the overcoming of this condition);
- it verifies the signal of the sensor of maximum charge of distribution line of the feed (stopping the distribution when the sensor intervenes and starting it again with a certain time of delay when the sensor permits it);
- it records the Kg of feed that have been consumed from the first day of the cycle;
- it records the litres of water that have been consumed from the first day of the cycle;
- it verifies in each moment the feed that is present.

The digital amplifier at 65.500 points with precision and a stability of 1 point on 65.500 and a termic drift of less than one point on 65.500 integrated on board of HP62 permits an exact control of the weighing, in order to connect every kind of load cells with an automatic procedure of cells calibration (no trimmers to adjust): pratically the precision of weighing system is the one that is declared of load cells.

It has small dimensions and it comes equipped in two versions:
HP62 model for panel mounting, with IP55 keyboard;
HP62/W model for wall mounting, with IP55 box.
