The ISUB6000-30GM85 is a flagship 6-meter ultrasonic distance and level sensor designed for demanding industrial automation tasks. Unlike traditional sensors that are locked to a single output type, the sensor series features a revolutionary "All-in-One" architecture. Operating at a frequency of approximately 65kHz, it delivers reliable non-contact measurement for liquids and bulk solids, ensuring operational efficiency in logistics, tank monitoring, and factory automation.

One Hardware, Infinite Possibilities
What sets the ISUB6000-30GM85 apart is its programmable core. Engineers no longer need to stock separate models for different control systems. By simply updating the firmware via the serial port tool, this single hardware unit can transform to output Analog signals (4-20mA, 0-10V), Digital Switching signals (NPN, PNP, Hysteresis modes), or Digital Data (TTL/RS232). This flexibility significantly streamlines procurement and simplifies on-site maintenance, allowing for rapid adaptation to changing project requirements.

Robust Performance in Harsh Environments
Engineered for reliability, the sensor is housed in a durable M30 casing with an IP67 protection rating. It features a narrow ±10° beam angle and a small 350mm blind zone, ensuring focused detection even in confined spaces. With built-in temperature compensation and protection against short circuits and reverse polarity, the ISUB6000 maintains high accuracy (±1% linearity) across a wide temperature range of -25°C to 70°C, providing data you can trust.

Typical Applications

Application-of-solid-material-level-detection-in-large-storage-silos-ISUB6000-30GM85

The ISUB6000-30GM85 is engineered to handle the complexities of measuring solid materials, such as plastic pellets, grain, animal feed, or gravel, in storage silos up to 6 meters high. The Challenge: In solid material applications, the surface is rarely flat—filling creates a cone shape, and emptying creates a funnel. Additionally, dust generation and abrasive materials frequently damage mechanical paddle switches or tuning forks. The Solution: Utilizing a 65kHz ultrasonic frequency, the sensor provides reliable non-contact measurement that ignores moderate dust suspension. Its robust IP67 housing prevents dust ingress, ensuring long-term durability without the wear and tear associated with contact sensors. Versatile Deployment: For precise inventory management, the sensor’s Analog Mode (4-20mA) can be calibrated using A1/A2 teaching points to map the silo's full and empty states, compensating for the material's angle of repose. Conversely, for process automation, it can be switched to Digital Output (PNP/NPN) to act as a high-level alarm, automatically stopping the conveyor feed when the hopper reaches capacity to prevent overflow.
