IES-PCI-423

Technical Specifications

Process Tanks and Vessels – The system includes a 50 L sump tank (SS 1.5 mm / PP 5 mm), an industrial cylindrical pressure vessel, and a transparent acrylic level tank (approx. 600 mm length) for conducting process control experiments involving liquid level and pressure.

Centrifugal Pump System – Two ½ HP centrifugal pumps operating on 230 V AC supply for fluid circulation and process simulation within the experimental setup.

Temperature Process Tank – Insulated process tank integrated with electric heater (1–3 kW) and thermostat for conducting temperature control experiments.

Process Piping Network – Industrial ¾″ CPVC / ½″ stainless steel piping system with ball valves and leak-proof fittings designed for safe and reliable fluid handling.

Flow Measurement System – Two flow transmitters / flow meters with measurement range 0–1000 LPH, providing 4–20 mA output signal and operating on 24 V DC supply.

Temperature Measurement System – RTD-based temperature transmitter with measurement range 0–100 °C and 4–20 mA output for accurate temperature monitoring.

Pressure and Level Measurement Instruments – Pressure transmitter (0–2.5 kg/cm² range) and level transmitter (0–500 mm range) with 4–20 mA output signals for monitoring process parameters.

Control and Actuation System – Thyristorized phase angle controller (4–20 mA input, 0–230 V AC output, 10 A capacity), two pneumatic control valves (½″ equal-percentage type), and electro-pneumatic (E/P) converter converting 4–20 mA signal to 3–15 psi.

Instrumentation and Electrical System – Includes panel meters (0–20 mA), PID controllers with single/dual input and 4–20 mA I/O, 230 V AC to 24 V DC power supply (5 A), and MS powder-coated electrical control panel with switches, indicators, DIN-rail terminals, ferruled wiring, and organized cable tray routing.

Air Supply and Mechanical Structure – Air compressor with 20–24 L tank capacity (~2 CFM, 1–2 HP motor) providing 5–6 kg/cm² working pressure, supported by a heavy-duty MS floor-mounted frame with caster wheels and locking brakes for mobility and stability.
