The Hydrogen Leak Detector (HLD) Sensor uses the Honeywell advanced compensation algorithm to detect Hydrogen leaks in different applications. Designed with precision and reliability in mind, the HLD Sensor employs cutting-edge Thermal Conductivity Detection (TCD) technology to deliver lasting performance for many applications that require a highly accurate solution without manual intervention for ten years.
Its advanced detection capabilities ensure the identification of hydrogen leakage of 50 ppm or greater. Honeywell HLD Sensors can be utilized in many industries, such as automotive, industrial safety equipment, and residential power generators.
The incorporation of TCD technology in the HLD sensor offers several key advantages over catalytic beads. These benefits include greater accuracy, extended sensor lifespan, and enhanced resistance to chemical poisoning. With these advantages, the HLD sensor gives users the confidence that both lives and assets are well-protected.
Features:
Applications:
The HLD sensor is typically adjacent to the hydrogen storage tank, hydrogen gas piping, fuel cell, or vehicle cabin.

Cynergy3 has both flowmeters and flow switches amongst its range of measuring instruments.
Cynergy3 manufacture flowmeters and flow switches that can accurately measure liquid volumes ensuring correct dispensing in a wide range of industrial applications. Our ultrasonic flowmeters can be specified to have a range of outputs and are commonly used in hot or cold beverage dispensing providing reliable, safe, consistent results for customers. The flow switch acts on demand to start or stop the flow of liquid avoiding over or under filling.
Coolant flow is another important application where monitoring flow is necessary to keep cooling systems working effectively. Our flow switches can be programmed to automatically manage flow, activating or deactivating pumps as needed to keep flow within the recommended parameters.
