CRYSOUND IA3104 Contact Ultrasound Sensor
The CRYSOUND IA3104 Contact Ultrasound Sensor helps maintenance teams detect internal leakage in valves handling pressurized gases and liquids. Instead of searching for an external leak, the sensor captures high-frequency ultrasonic signals created by fluid or gas passing through a leaking valve.
Operators place the sensor against the valve body or adjacent piping. Ultrasonic energy travels through the metal surface to the sensor, allowing the system to evaluate activity inside the valve without disassembly.
The IA3104 combines contact ultrasonic sensing with intelligent analysis and a guided inspection workflow. The system handles data collection, feature extraction and leak diagnosis. As a result, maintenance teams can standardize valve inspections and reduce reliance on subjective listening techniques.
Its Valve Leak analysis evaluates acoustic characteristics such as sound level, frequency spectrum and energy. The system can classify valve condition as Normal, Suspected Leak or Leak Detected. It can also estimate leak severity to support maintenance decisions.
This non-intrusive approach suits preventive maintenance, troubleshooting and condition assessment of critical valves. Applications can include oil pipelines, natural gas systems, process piping and other pressurized gas or liquid systems.
The IA3104 is not explosion-proof. CRYSOUND offers the IA3105 IECEx Contact Ultrasound Sensor for applications that require an explosion-proof version. Customers should confirm hazardous-area requirements before selecting a sensor.

Product Features
Detect Internal Valve Leakage Without Disassembly
The IA3104 gives maintenance teams a non-intrusive method for evaluating internal valve leakage. Operators attach the contact ultrasound sensor to the valve body or nearby piping rather than opening the valve or interrupting the process.
Internal leakage creates high-frequency ultrasonic energy as pressurized gas or liquid passes through the valve. That energy travels through the valve and piping material. The IA3104 captures these ultrasonic signals for analysis.
This approach can help teams inspect ball valves, plug valves, check valves, butterfly valves and other common valve designs. Because testing does not require valve disassembly, facilities can perform more frequent condition checks while reducing unnecessary maintenance work.
Standardized Guided Valve Inspection
Traditional valve inspection can depend heavily on technician experience. The IA3104 helps create a more consistent process through a guided inspection workflow.
The system directs data collection at defined measurement points and then analyzes the captured ultrasonic information. This process reduces manual recording and eliminates much of the post-processing normally required after an inspection.
Standardizing the workflow can also improve repeatability between inspections and technicians. Maintenance teams can establish a consistent approach for checking critical valve assets across a facility.
Automatic Valve Leak Diagnosis
The IA3104 uses intelligent analysis to evaluate ultrasonic characteristics associated with valve condition. The system analyzes factors such as sound level, spectrum characteristics and acoustic energy.
It then classifies the valve condition as Normal, Suspected Leak or Leak Detected.
This automated approach reduces the need for operators to manually interpret complex ultrasonic signals. It also provides a clearer result for maintenance personnel who need to determine whether further investigation or corrective action is necessary.
Teams can compare results across different operating conditions to support additional verification.
Estimate Leak Severity for Better Maintenance Decisions
Finding a leaking valve answers only part of the maintenance question. Teams also need to understand how serious the problem may be.
The IA3104 can estimate leakage severity based on captured ultrasonic characteristics. This information helps maintenance personnel determine an appropriate response.
For example, a result may support continued monitoring, scheduled repair or more urgent corrective action. Consequently, teams can prioritize maintenance resources according to valve condition rather than treating every finding the same way.
Non-Intrusive Testing Supports Predictive Maintenance
The contact measurement method allows maintenance teams to evaluate valves without dismantling equipment.
This capability makes the IA3104 well suited to preventive and predictive maintenance programs. Operators can collect condition information during inspection routes and identify valves that require closer attention.
Regular inspection can also provide valuable comparison data over time. Changes in ultrasonic activity may help maintenance personnel recognize developing valve problems before they become more significant.
High-Sensitivity Ultrasonic Measurement
The IA3104 provides peak sensitivity greater than 75 dB according to ISO 12714:1999. It also features a noise floor below 10 μVRMS across 15 to 70 kHz.
These measurement characteristics help the sensor capture high-frequency acoustic signals associated with internal leakage.
The sensor uses an IEPE power supply rated at 28 V and 6 mA. This configuration supports its use within compatible CRYSOUND ultrasonic inspection systems.
Compact Sensor for Industrial Field Inspections
The IA3104 measures 35 × 40 × 135 mm, excluding the waveguide, and weighs approximately 350 g.
Its compact size makes it practical for technicians who need to inspect multiple valves during maintenance rounds.
The sensor operates from -20°C to +50°C and supports operating humidity from 10% to 95% in non-condensing conditions. It also carries IEC 61010-2-033:2023 safety compliance and IEC 61326-1 EMC compliance.
Choose the Correct Sensor for the Area Classification
The IA3104 is CRYSOUND’s non-explosion-proof Contact Ultrasound Sensor. Therefore, users should not assume that it is suitable for classified or explosive atmospheres.
For applications requiring an explosion-proof version, CRYSOUND identifies the IA3105 IECEx Contact Ultrasound Sensor as the appropriate model.
Westech can help review the application and area requirements before equipment selection.
