Product Overview
The Multi Process Trainer Prozessi PX 24 provides a comprehensive platform for studying five advanced process control strategies on a single system. The trainer consists of an SS304 stainless steel water supply tank and a submersible pump providing continuous closed loop circulation through a transparent acrylic process tank (0-100% graduated scale). An electronic level transmitter (0-250 mm range, 4-20 mA output) monitors tank level. Three orifice meters with two differential pressure transmitters (capacitance type, 0-200 mm range, 4-20 mA square root output) measure flow at multiple points. Three rotameters (10-100 LPH each) provide visual flow indication. A 1/4″ pneumatic control valve (3-15 psig input, air to close, linear characteristic) regulates process flow. An I/P converter transforms 4-20 mA signals into 3-15 psig pneumatic commands. Process signals connect to an NI USB-6001 data acquisition device (14-bit, 20 KS/S, 4 analog inputs, 2 analog outputs) via USB communication to a computer. An air regulator (0-2.5 kg/cm2) and two pressure gauges monitor pneumatic pressure. A 24 VDC power supply energizes transmitters and converters. The Multi Process Trainer measures 600W x 500D x 1600H mm and includes LabVIEW-based software with trend plots, data logging and export functions. It requires clean, oil and moisture-free compressed air at 2 Bar, 50 LPH consumption.

Construction and Design
The Multi Process Trainer Prozessi PX 24 is mounted on a vertical standalone structure measuring 600W x 500D x 1600H mm. An SS304 stainless steel supply tank at the top provides water for the closed loop system. A fractional horse power submersible pump circulates water through transparent acrylic process tank fitted with 0-100% graduated scale. An electronic level transmitter (0-250 mm range, 4-20 mA output) monitors tank level continuously. Three orifice meter stations are installed in series with flow paths, each paired with a differential pressure transmitter (capacitance type, 0-200 mm range, square root output). Three rotameters (10-100 LPH each) provide simultaneous visual flow indication at different system points. A 1/4″ pneumatic control valve (3-15 psig input, air to close, linear characteristic) regulates flow through one of the process paths. An I/P converter transforms 4-20 mA electrical signals into 3-15 psig pneumatic signals for valve actuation. All analog signals from the level and differential pressure transmitters connect to an NI USB-6001 data acquisition module providing 4 analog inputs and 2 analog outputs. The DAQ device interfaces with a computer through USB communication. An air regulator (0-2.5 kg/cm2) and two pressure gauges (0-2.5 kg/cm2 and 0-7 kg/cm2) monitor pneumatic system pressure. A 24 VDC power supply (0.7 A) energizes the transmitters and I/P converter. The Multi Process Trainer requires clean, oil and moisture-free compressed air at 2 Bar pressure with 50 LPH consumption.
