Overview

This high-quality remote water leak sensor is wall-mounted, with a maximum detection distance of up to 2000m. It can operate normally in environments ranging from -20℃ to +60℃ and 0%RH to 80%RH. The SUCH remote water leakage sensor supports DC 10-30V power and has RS485 or relay outputs. It is easy to install and connect to existing systems and is widely applicable to communication base stations, hotels, restaurants, computer rooms, libraries, archives, warehouses, equipment cabinets, and other places requiring water accumulation alarms.

Feature

Waterproof Strip Design: Waterproof strips at the seams of the casing isolate the device from the external environment, offering excellent moisture resistance.
Waterproof Adhesive Sealing: Waterproof adhesive is used at the interface of the remote water leakage sensor to ensure the internal circuitry is isolated from the outside environment.
Four-Core Waterproof Cable: Black shielded cable, waterproof and oil-proof, with strong anti-interference capabilities and stable signal transmission.
High Protection Rating: The remote water leak sensor features a waterproof casing, allowing for extended use in harsh environments such as humid and dusty conditions.

FAQ

Q1: Are remote water leak sensors affected by humidity? ❯

Normal humidity will not trigger an alarm. Water leak sensors are designed to react only to contact with liquid water, not to air humidity.

Q2: Can remote water leak sensors be reused after testing? ❯

Yes. Most water leakage sensors and detection cables can be reused after a drying check.

Q3: How often should remote water leak sensors be tested? ❯

It is recommended to test remote water leak detection sensors monthly or quarterly, especially in critical environments such as data centers or industrial facilities.

Useful remote water leak sensor for a warehouse

I got this remote water leak sensor for a warehouse area where a small leak could go unnoticed for quite a while. The wall mounting made it easy to put near the spot I wanted to monitor. I went with the relay output so it could trigger an alarm when water was detected. The setup was pretty straightforward, and it’s been doing what I need so far.
