Screen changer controller

Screen changer controller types:
'CLOSED LOOP' "TIME CYCLE™" Controllers:

The CLOSED LOOP algorithm uses our proprietary Screen Guide & Resolver Assembly™ to monitor and ensure a consistent rate of screen movement.
TIME CYCLE™ based controls operate on an algorithm that generates an operating cycle by which the screen advances in time cycles at a constant rate. The rate (inches or mm per hour) of screen travel is programmable and is automatically maintained by means of a feedback loop - the Resolver Assembly™.
The controls automatically compensate for minor variations in processing conditions such as fluctuations in head pressure or water temperature to maintain a consistent rate of screen advancement. This allows for fine tuning to the specific parameters of a given application, maintaining steady head pressure and conserving screen consumption.

'CLOSED LOOP’ “PRESSURE OVERRIDE™ Controllers:
The CLOSED LOOP algorithm uses our proprietary Screen Guide & Resolver Assembly™ to monitor and ensure a consistent rate of screen movement.
‘CLOSED LOOP’ “PRESSURE OVERRIDE™" controls incorporate all the features of the TIME CYCLE™ algorithm, i.e., a constant rate of screen advancement is maintained via a feedback loop.  The additional PRESSURE OVERRIDE™ (or Differential ΔP Pressure) feature automatically increases the rate of screen advancement by continuously monitoring the pressure before the screen (P1) - or the differential pressure across the screen (ΔP) -  to maintain uniform processing pressure (head pressure). The distance of screen advancement in both Time and Pressure Cycles is programmable to achieve a precise rate of movement, allowing for fine tuning to the specific parameters of a given application.

PLC based FLIP/FLOP™ (On/Off) Controllers:
The operating mode of these controls is based on an ON/OFF algorithm which produces repetitive, cyclical rates of screen travel. Parameters settings can be modified via the PLC display.
