Transducer Smart Setup
Read full descriptionHide full description
The Transducer Smart Setup app is designed to make transducer setup as simple and automated as possible by reading data matrix codes on Bruel & Kjaer transducers and seamlessly transferring the information to PULSE Reflex measurements. Using the smartphone’s camera, you can perform a quick scan of the transducer’s data matrix code to read the transducer data and its orientation. The data matrix code also gives you instant access to specifications, documentation and calibration data. In addition, you can scan customized 2D labels attached next to the transducers to read transducer position and node ID. For transducers without data matrix codes, the app will recognize the transducer and its orientation and allow you to add associated data, minimizing the risk of data entry errors. Projects containing the test setup are exported as .xml files using an email account, a cloud storage service or iTunes and uploaded to the Hardware Setup Table in PULSE Reflex measurements. In addition, PULSE Reflex measurements recognizes which transducer is plugged into which input connector, eliminating the need to trace cables.
Heli Gauges
This app provides remote engine and weight data for helicopter operations, specifically for external sling load tasks. It displays critical information on compatible Apple devices, enhancing pilot situational awareness and safety during flight.
- Remote engine gauge display
- FLI repeater functionality
- Slaved indicator for load data
- Bluetooth data acquisition

The Heli Gauges App Patent No. US 10,780,995 B1 is for use in Helicopter External Sling Load Operations (HESLO). It is designed to be used with either the iPad Mini 5 or greater and iPhone 14 or greater. The App provides remote mounted engine gauges for the B407, AS350B2 (non-VEMD) as a "Remote Gauge" and for the AS350B3 (H125) as the "FLI Repeater". In addition, there is a Slaved Indicator which is used to replace the Onboard Systems Remote Analog Gauge which cannot be used with the new Onboard C-40 Load Indicator. For the Remote Gauge or FLI Repeater App, engine data is received via Bluetooth from either our ETM1000 or DCS1100 Data Acquisition Unit (DAU), respectively. For the Slaved Indicator, the App receives weight data from our SIB100 system via the Onboard C-39, C-40 or MXI load indicators. The iPad or iPhone is then mounted next to the external load window via approved mounts for the AS350 (Dart and MVPK windows) by locating the instruments in the same sight line as the external load. This helps to reduce pilot fatigue, exceedances, and improve overall safety.

Verdict
The clearest difference is update cadence: Heli Gauges at every 6 months against Transducer Smart Setup's every 42 months. Transducer Smart Setup's advantage is iOS requirement (8.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
