Closely Monitor Machines with SDT340

The SDT340 Data Collector — in combination with the UAS3 Analysis Software — is a multidisciplinary predictive maintenance solution customized to meet the unique requirements of the industry.

By combining vibration, ultrasound, rotational speed and temperature, the user can monitor the machines’ health, foresee problems, and reduce energy costs. UAS3, the cross-platform and multi-technology software that analyzes and organizes the data from desktop computers or servers, can successfully organize the predictive maintenance program.

Ultrasound for Electric Power Reliability

Scope of the Application

  • Mechanical: Detects defects in any mechanical system
  • Lubrication: Avoids insufficient or excessive lubrication while making sure the bearings are well greased
  • Leaks: Situates vacuum leaks and pressure in loud conditions
  • Valves: Checks the valves’ tightness
  • Hydraulics: Checks for obstructions and leaks in any hydraulic system
  • Tightness: Finds out the tightness of any enclosed volume
  • Electrical: Checks for tracking, arcing and corona in high- and medium-voltage systems
  • Steam: Looks for defective steam traps and other components that are leaking


  • The 3.5" color display offers a crystal-clear image in the darkest environments.
  • With enhanced signal data, the user can record time waveform data for up to 10 minutes.
  • The user can recall prior data for in-field acquisition trending and alarms.
  • Thanks to UAS3’s user-friendly interface, data can be collected in “off-route” mode.
  • The user can boost the field productivity with the spectrum, split-screen view, on-screen time signal and icon navigation.
  • With focUS Mode, the user gets improved impact detection and sees defects that others could not.
  • For enhanced in-field detection, pan and widen time signal or spectrum and determine the top values.
  • SDT340 high-definition Bluetooth headset helps to get rid of cables

Detect, Trend and Analyze Ultrasound and Vibration

Continuing the SDT legacy of excellence, SDT340 provides trustworthy data for the customer. By viewing the ultrasound and vibration time signal along with spectrum directly on the color display, SDT340 detects, trends and analyzes asset health.

With Ultranalysis® Suite 3, users can manage the results and organize the strategy of condition monitoring. With its flexibility, it is easy to control any combination of tasks and assets.

Connected to Goals

A trustworthy asset delivers its programmed value when it is needed the most. Even if the responsibility for reliability is upon everyone, it is the maintenance that is relied on first when things go wrong. For the same reason, the SDT340 links maintenance to reliability in incredible ways.

Inspectors are kept connected to their assets by SDT340. Live timewave and spectral views, on its high-resolution color screen, allow inspectors to carry out in-the-field diagnosis and analysis — a job that was previously done in the office.

High-Signal Resolution, or HSR, is a game-changing feature. Enhanced sensitivity and improved sampling rate offer confidence and precision to the diagnosis. Nevertheless, mechanical defects are very good at hiding. HSR connects inspectors with the tools to uncover those hard-to-decipher anomalies.

An international standardized unit of measurement for ultrasound has the capacity to link with every ultrasound inspector across the globe, regardless of the tool they employ. This revolution can be led by SDT340.

Connected to Partnership

The innovations on the SDT340 are proof of the connected partnerships developed with the customers. The SDT340 aligns completely with SDT’s corporate visions in numerous ways.

SDT340 connects the customers to the company’s vision to be the technological pioneer in software, ultrasound hardware and training. SDT is considered the thought leader for ultrasound globally, and SDT340 shows how the company continues to push the boundaries of this significant technology.

Customer partnerships link the company to their pain and help in thinking creatively, improving existing ideas, exploring new ideas and developing hardware platforms that represent new possibilities.

By remaining connected to the partnerships, the company is able to continue creating solutions that are inventive, effective, precise, reliable, robust, necessary, easy to use and affordable. The connected partnerships empowered the creation of the SDT340.

Team Work

Numerous maintenance teams work in a silo-mentality. SDT340 breaks down those barriers; and stimulates teamwork. It also helps extend the circle of trust beyond the maintenance department along with inviting input from each stakeholder.

Knowing a machine will fail does not stop it from failing, particularly when the knowledge is not shared. SDT340 develops a naturally collaborative atmosphere by making asset condition information ubiquitous. Teams enter the next outage with a game plan.

Ultrasound data reveals more information about the health of the assets.

Collaborative Partnerships

Collaboration is not confined to the organization, SDT340 leads way for collaborative partnerships between CM Practitioner and Solutions Provider. The atmosphere for B2B relationships is fertile and the majority of the organizations are opening themselves to cooperate with solutions providers who instill the best interests of their client directly into their mission statement.

Security and Ergonomics

With a memory backup of 4.256 GB, SDT340 has 16 times more storage than SDT270. The SDT340 employs only internal memory storage. The use of pluggable memory and SD card introduces the risk of data mismatch, data loss and PC viruses’ transmission.

SDT340’s luminous color display sports crystal-clear resolution on a large 340 × 480, 3.5" screen. Intelligent icon navigation communicates to the user in any language while a split-screen view offers versatility to in-the-field tasks.

Improved keypad, with 14 buttons, enhances the user experience. One function with one key concept reduces button pushes and encourages efficiency.

Permanent mount sensors, an industry trend, support ergonomics, safety and data integrity.

As an accessory to protect and clean the SDT340, a holster is available.

The durable nylon holster for the SDT340 avoids dust ingress, and usual wear and tear, while maintaining the covered ultrasound unit spotless.

Lifetime Warranty

SDT’s unprecedented and unparalleled Lifetime Warranty helps keep the instrument calibrated and well cared for. The user never pays for a repair again. SDT develops better products that stand the test of time. Even though this might sound boastful, the company is passing the rewards of this confidence to the customers. The reputation backs everything that the company does.
