Dry Contact Industrial Water Leak Detector

Features

Stable & Reliable Performance

Constructed with industrial-grade electronic components, the Dry Contact Water Leak Detector delivers consistent, high-sensitivity detection while minimizing false alarms caused by external factors such as dust, humidity, or electrical interference. It adopts an electromagnetic compatibility design, incorporating anti-surge, anti-static, and anti-EFT protection to ensure stability in harsh industrial or data center environments.

Adjustable Sensing Sensitivity

The detector features a 2-position 4-gear DIP switch on the front panel, allowing users to customize sensing sensitivity to match their specific environment and detection requirements. This flexibility enables it to adapt to different scenarios—from sensitive server rooms where even small leaks must be detected to industrial areas where higher tolerance for minor moisture is acceptable.

Easy Operation & Installation

Designed with standard industrial modules and DIN rail mounting, the detector can be easily installed and wired on-site using accessible terminals. It requires no complex programming or specialized training to operate: when a leak is detected, the relay activates automatically, and the leakage indicator illuminates. Once the leak is resolved, the detector resets to normal operation without manual intervention.

Local Sound and Light Alarm

Upon detecting liquid leakage, the detector triggers a local sound and light alarm: the panel’s LED leakage indicator remains illuminated, and an internal buzzer emits a loud, audible alert. This dual warning system ensures that on-site personnel are immediately notified of leaks, enabling rapid response to minimize damage.

One-Key Mute Function

For situations where the audible alarm may be disruptive (e.g., after personnel have been alerted and are addressing the leak), the detector includes a one-key mute function. A dedicated button on the panel allows users to silence the buzzer while maintaining the illuminated LED indicator, ensuring visibility of the alert without unnecessary noise.

Remote Monitoring Integration

Equipped with a dry contact relay output, the Dry Contact Water Leak Detector can be seamlessly integrated with various third-party monitoring systems, including building management systems (BMS) and security platforms. This enables remote monitoring of leak status, allowing users to receive alerts and manage the system from off-site locations.

FAQ

How does the Dry Contact Water Leak Detector work?

The detector works in conjunction with a non-location water leak sensing cable. When the cable comes into contact with water, it creates a short circuit, which the detector recognizes as a leak signal. The detector then activates the local sound and light alarm and sends a dry contact (NO/NC) output signal to third-party devices such as sirens, BMS systems, or monitoring platforms to trigger further actions.

Does the detector support Modbus protocol?

No, this is a dry contact sensor and does not support Modbus protocol. It uses simple relay contact signals for communication, which ensures reliable integration with a wide range of third-party systems without the need for complex protocol configuration.

Can the detector identify the exact location of a leak?

No, this is a non-locating leak detector. It is designed to alert users to the presence of a leak but does not provide precise location data. For applications requiring leak localization, a dedicated locating water leak detector and sensing cable would be necessary.

How do I adjust the sensing sensitivity?

The detector features a 2-position 4-gear DIP switch on the front panel. You can adjust sensing sensitivity by toggling these switches, with options ranging from high sensitivity (for detecting small leaks) to lower sensitivity (for reducing false alarms in humid environments). Refer to the user manual for specific switch configurations.
