Product Description

Dwyer water leak detector with SPST/SPDT relay and 85 dB audible alarm for facility monitoring. Detects water at 1/32 inch gap, operates 0 to +50°C, runs on 24 VDC or batteries. Ideal for HVAC, data centers, and building protection applications.

Frequently Asked Questions

What is the Dwyer WD3-BP-D1-A water leak detector used for?

The Dwyer WD3-BP-D1-A water leak detector protects equipment by detecting water presence in HVAC condensate pans, data center subfloors, and near sump pumps or drains. It triggers an 85 dB audible alarm and a relay output for remote monitoring, preventing water damage in commercial and industrial facilities.

What are the specifications of the Dwyer WD3-BP-D1-A water leak detector?

The Dwyer WD3-BP-D1-A detects water at a 1/32 inch gap, operates from 0 to +50°C, and runs on 24 VDC or a 3V CR2450 lithium battery. It features an SPST relay (battery model) or SPDT relay (external power model), with an 85 dB alarm at 30 cm and a red LED for water alarm.

Where to buy the Dwyer WD3-BP-D1-A water leak detector in Singapore?

3G Electric supplies the Dwyer WD3-BP-D1-A water leak detector to Singapore. We source and deliver this model, handling logistics and customs clearance for your facility. Contact us for availability and lead time on orders.

How to install the Dwyer WD3-BP-D1-A water leak detector?

Install the Dwyer WD3-BP-D1-A by attaching the adjustable mounting bracket to a flat surface using adhesive strips or screws. Position the detector so the conductive strips on the bottom contact water at the 1/32 inch detection gap. For battery models, insert the 3V CR2450 lithium battery; for external power, connect 11 to 27 VAC/DC.
