Where these instruments run
Application Metrology on the Line: Weld, Bolt and Fit Stations
What an in-line sensor must actually resolve at a weld, bolting or fit station, and the error sources that dominate before part tolerance does.
- Tolerance band to resolve
- 0.20 mm
- Allowable share of band used by the sensor
- 10 percent
- Working distance available
- 180 mm
Application CIP and SIP: What the Sensor Survives and Proves
How instrumentation behaves inside a clean-in-place circuit: the chemistry it sees, the failure modes it causes, and how cleanability is verified.
- Caustic wash step
- hot, 1 to 3 percent
- Acid passivation step
- cold to warm, dilute
- Intermediate rinse
- conductivity-limited
Application Instrumentation in a Water Treatment Train
How sensors behave in a real treatment plant: coagulant and DO loops, sample points that lie, biofilm, dry-out and the maintenance plan that decides it all.
- Turbidity window
- biofilm and scaling
- pH glass
- junction clogging and dehydration
- Redox electrode
- surface poisoning, needs abrasion
Engineering notes
- Engineering note
4-20 mA Loop Fault Finding: A Six-Fault Order
Field order for 4-20 mA loops: live zero, voltage headroom at 20 mA, ground loops and shield bonding, plus the one measurement that splits each fault class.
- Loop supply
- 24 V DC
- Receiver input resistor
- 250 ohm
- Cable loop resistance, illustrative run
- 35 ohm
- Engineering note
IP67 and IP69K: Test Method, Not Protection
Why IP67 and IP69K are not a ranking: the water test behind each digit, and what CIP and SIP cycles really do to housings, gaskets and cable entries.
- EPDM, hot water and steam
- good
- EPDM, mineral oil and grease
- poor
- FKM, caustic at elevated temperature
- variable
- Engineering note
Laser Triangulation vs Time-of-Flight
How laser triangulation and time-of-flight sensors fail on shiny, dark and transparent targets, and which mechanism decides between them.
- Required resolution
- decides the mechanism first
- Standoff available
- decides the second
- Target optical behaviour
- decides the model within the mechanism
