Where it is used
Typical tasks
- Bearing and pump mechanical defects
- Air and gas leaks
- Electrical defects
- Valve testing
- Pump cavitation
- General diagnostics for programs where the main focus isn't set yet
Overview
ULTRAChecker is the universal detector in the Checker Range: the same platform can be pointed at mechanical defects, air and gas leaks, electrical problems, or valve checks without switching instruments. It isn't a more powerful version of the specialized Checkers, it's a broader one - it trades depth in one area for coverage across several tasks with a single unit.
Features
Broad coverage
- Mechanical monitoring of bearings, gears, and pumps
- Compressed air, process gas, and vacuum leaks
- Electrical defects: corona discharges, arcing, partial discharges
- Valve testing for internal leaks and operability
Ease of use
The instrument needs no task-specific setup: turn it on and start working. Minimal controls and a fast switch between inspection points set it apart from instruments built around routes and configurable measurement profiles.
Streaming screen
A firmware update adds a continuous histogram mode on top of the standard screen: real-time visualization of the ultrasound signal, with a switch between Default and Streaming screens using the On/Off button.
Application areas
Mechanical
- Bearings: early detection of wear, insufficient lubrication, cage damage, and raceway defects
- Pumps and compressors: cavitation, mechanical damage, seal issues, imbalance
- Valves: tightness verification, leak detection, open/close monitoring
Leaks
- Compressed air: lines, connections, receivers, pneumatic tools
- Process gases: nitrogen, oxygen, argon, natural gas, inert and chemical gases
- Vacuum: vacuum pumps, chambers, seals
Electrical
- High-voltage equipment: corona discharges, insulation tracking, contact arcing, partial discharges
- Low-voltage equipment: poor contacts, overloads, breaker arcing, fuse issues
Role in a reliability program
ULTRAChecker fits ODR (Operator-Driven Reliability) programs, where operators run the daily inspection themselves: the instrument needs no specialized training, and early detection lets a problem get handed off for deeper analysis to a specialist with SDT270 or SDT340.
A typical sequence: ULTRAChecker runs a fast check across a wide range of assets and task types, SDT270 works through the problems it finds in more detail with data logging and trends, and SDT340 adds full spectral analysis and vibration diagnostics for the most critical cases.
Firmware update
The update is installed through the SDT Updater software: connect the instrument to a computer via USB, Windows installs the driver automatically, then the update runs as a standard install. Once updated, the switchable streaming screen mode with a continuous histogram becomes available on top of the standard screen.
Comparison with other Checkers
| Checker | Specialization | When to use |
|---|---|---|
| LEAKChecker | Air and gas leaks | Ongoing leak energy audits |
| LUBEChecker | Bearing lubrication | Lubrication monitoring programs |
| TRAPChecker | Steam traps | Steam systems and boiler rooms |
| TIGHTChecker | Seal tightness | Tightness testing |
| HATCHecker | Ship hatches | Marine and port inspections |
| ULTRAChecker | Mechanical, leaks, electrical, valves | No single task settled yet, need coverage across several areas |
When to choose ULTRAChecker
ULTRAChecker fits programs that haven't settled on one recurring task yet: a small facility where one instrument needs to cover mechanical, leak, electrical, and valve inspections, operators who need a simple daily check with no training, and programs just starting with ultrasound testing that don't yet know which area will become the main focus.
Once one task becomes a permanent, growing workload, it makes sense to move to a specialized instrument in the same series: LEAKChecker for a recurring leak energy audit, LUBEChecker for lubrication monitoring, TRAPChecker for steam systems, and so on - the same working principle, tuned for a single task.
Checker Range
ULTRAChecker is part of the Checker series:
- LEAKChecker - air and gas leaks
- LUBEChecker - bearing lubrication monitoring
- TRAPChecker - steam trap testing
- TIGHTChecker - tightness testing
- HATCHecker - ship hatch tightness
- ULTRAChecker - universal detector for several areas at once
