Description
Hidden hot spots inside rotary air compressors cause oil carbonization and catastrophic rotor bearing seizure. Point the Fluke 568IR Infrared Contact Type thermometer kit at bearing caps and pipe manifolds to diagnose heat buildup instantly. We rate this two-in-one meter from minus forty to eight hundred degrees Celsius. Attempting to measure polished chrome shafts without adjusting surface emissivity yields false low readings.
We tore down the instrument casing to inspect the optical and electronic layout. An infrared sensor pairs with a front germanium lens to focus thermal radiation onto a thermopile detector. Solid-state microprocessor chips mount to shock-dampened circuit boards inside a rugged thermoplastic housing. A secondary thermocouple contact block utilizes gold-plated leaf springs to ensure zero contact resistance during physical probe validation testing on hot dynamometer brake drums.
Hardware Performance Matrix Breakdown
Preventative maintenance requires rapid non-contact scanning combined with verified contact probe measurements. Maintenance supervisors monitor these seven diagnostic hardware features across daily plant inspections.
- 50 to 1 distance-to-spot optical ratio measures small hot spots from fifty feet away safely.
- Infrared temperature range spans minus forty to eight hundred degrees Celsius for industrial plants.
- Type-K thermocouple input provides physical contact verification on questionable thermal surfaces.
- Adjustable emissivity table includes pre-set material values to eliminate shiny metal scan errors.
- Internal data logging stores ninety-nine data points to document plant compressed air surveys.
- Two-color visual high and low alarms flash screen alerts when components exceed heat limits.
- USB interface cable exports logged thermal points to computer software for trend analysis.
Dyno Bench Load Telemetry
Monitoring dynamic air tool tests with this sensor tracks motor heat under 35 CFM at 90 PSI dynamic load. Rotor shaft free speed registers 12000 RPM but loaded grinding pulls rotation down to 8200 RPM. Shop air lines lose 13 PSI dynamic pressure drop through 50 feet of hose. Adiabatic cooling causes a 28 degrees Fahrenheit exhaust drop, freezing moisture on exhaust deflector cones. Breakaway torque logs at 38 foot-pounds with noise levels reaching 91 dBA.
Field Service Trade Offs
Taking infrared scans through airborne oil mist or steam scatters the optical beam and produces inaccurate readings. Field mechanics who neglect surface emissivity adjustments on bare cast iron must avoid infrared diagnostics because shiny metal reflects ambient shop heat. Always steady the laser with two hands.
- Wipe the front infrared lens with clean cotton swabs to clear oily shop dust films.
- Calibrate contact probe channels against boiling water before conducting critical dyno tests.
- Store the unit inside its hard case to prevent lens scratching from loose tool chest items.
