Sensors, transmitters & control loops — measuring and regulating industrial processes.
Orifice-plate DP flow meter with impulse tubing, a three-valve manifold, and square-root extraction split across transmitter and receiver.
Fill and drain a vessel while comparing a hydrostatic DP transmitter (dry/wet leg) against roof-mounted radar time-of-flight sensing.
Calibration bench with hand pump, isolation/vent manifold, diaphragm transmitter and a powered 4–20 mA receiver — trace the full loop voltage budget.
Pt100 RTD vs. thermocouple sensing in a stirred bath — compare 2/3/4-wire lead compensation, cold-junction compensation and sensor faults.
Explore a double-acting piston cylinder — directional spool, cap/rod chambers, load spring, friction and end stops.
Compare cascade, single-loop and manual architectures on a heated vessel with a master temperature and slave flow PI loop.
Trace voted pressure sensors through a latched shutdown decision, solenoid, pump stop and a spring-return isolation valve with closure proof.
Compare a fail-closed and fail-open spring-return valve on the same demand, then lose air, power, or jam a stem.
Inspect a globe valve cutaway and compare linear vs. equal-percentage trim against the installed flow characteristic.
