ISUB4000-30GM85

ISSR 4M All-in-One Ultrasonic Level Distance Sensor Switch/Analog/Digital Output

Features:

4 meters fully integrated ultrasonic material ranging liquid level distance sensor

  • All-in-One Universal Hardware Architecture:A single sensor hardware unit supports multiple output logics. By simply upgrading the firmware via a TTL serial tool, users can flexibly switch between Analog (4-20mA, 0-5V, 0-10V), Switching (NPN, PNP), and Digital outputs. This "one device, multiple uses" capability significantly reduces inventory pressure and spare parts complexity
  • Smart Range Configuration & High-Precision Detection:Offering a wide physical detection range of 200mm to 4000mm, the sensor is deeply integrated with A1/A2 Teach-in functionality. This allows users to customize the start and end points of the detection window within the adjustable range of 220mm to 4000mm. This flexible "distance-on-demand" setting, combined with ±1% full-scale repeatability, effectively masks background interference and enhances control precision within the specific target zone
  • Intelligent Environmental Adaptation:Features built-in temperature compensation to correct sound velocity deviations caused by temperature changes in real-time. Combined with a rugged IP67-rated housing, it effectively resists outdoor rain, humidity, and dust intrusion, ensuring long-term stability even in harsh operating conditions
  • Multi-Mode Output Support:Comprehensively covers standard industrial interfaces, including current loops, voltage outputs, hysteresis mode switching outputs, and TTL232 digital interfaces. This ensures seamless integration with PLCs, microcontrollers (MCUs), Industrial PCs (IPCs), and various other host systems
  • Optimized Beam Design:Utilizes a ~75kHz transducer frequency paired with a ±8° narrow beam angle. This design concentrates ultrasonic energy to effectively filter out clutter interference from surrounding objects, focusing specifically on the precise positioning of the target object or liquid level

The ISUB4000-30GM85 series is a fully integrated ultrasonic ranging sensor capable of high-precision detection from 200mm to 4000mm. Its core competitive edge lies in its "Fully Integrated & Configurable" architecture. Users no longer need to stock diverse hardware models; by simply updating the firmware via a TTL serial tool, the output logic can be instantly switched between Analog (4-20mA/0-10V), Switching (NPN/PNP), or Digital signals. This "Software-Defined Hardware" innovation significantly reduces spare parts inventory costs and maximizes on-site commissioning flexibility.
In terms of application, the sensor leverages the inherent advantages of non-contact ultrasonic technology. Unlike traditional contact sensors (such as float switches or submersible probes), it operates without contacting the medium, thereby completely eliminating risks of mechanical wear, jamming, or chemical corrosion. Whether monitoring corrosive acids, viscous sludge, or hygienic food storage tanks, it delivers "Zero-Contact, Maintenance-Free" performance. Furthermore, for solid material level measurement (e.g., grain silos, coal hoppers), its optimized acoustic algorithms effectively penetrate dust and handle uneven material surfaces. It also serves as an ideal choice for AGV obstacle avoidance and object detection, acting as a versatile solution for industrial automation.

Typical Applications

Application of hydrological lake and river water level monitoring-ISUB4000-30GM85

The ISUB4000-30GM85 series (4-meter range) fully integrated ultrasonic sensor is ideal for smart water conservancy and urban flood control monitoring systems. In practical applications, the sensor can be installed on the side of a bridge or on a support structure, providing non-contact detection of the water surface in rivers or irrigation canals vertically downwards. With its IP67 protection rating and temperature compensation, it can accurately report water level data even in harsh outdoor environments such as heavy rain, intense sunlight, or large diurnal temperature variations. By configuring the output mode as a 4-20mA analog signal or TTL digital signal via serial port, the sensor can be directly connected to an RTU (Remote Terminal Unit) or a wireless data transmission module. When the water level changes, the data is transmitted to the monitoring center in real time, helping managers to monitor river flood conditions, irrigation water volume, or water depth in low-lying urban areas. This enables automated sluice gate control or flood warnings, effectively replacing traditional manual ruler observation.
