Dwyer 605-11 Differential Pressure Transmitter 25 Psi

Product Description

The DWYER 605-11 is a differential pressure transmitter with integrated indication, designed to measure and display differential pressure in HVAC, building automation, and light industrial systems. It delivers a 4-20mA output signal, making it compatible with standard building management and control systems. The unit handles a maximum working pressure of 25 psi and operates across a temperature range of 20 degrees F to 120 degrees F. With female 1/8-inch thread connections, it installs directly into standard pressure ports. Weighing 2.5 pounds, it is a compact and practical instrument for field installation by HVAC controls technicians and instrumentation specialists.

The DWYER 605-11 is suited for residential and commercial HVAC applications where differential pressure monitoring is required, such as across air handlers, filters, coils, or duct systems. The on-board indication allows technicians to read pressure directly at the sensor without a separate gauge or handheld meter, reducing diagnostic time during commissioning and service calls. Its 4-20mA signal integrates cleanly into DDC panels, PLCs, and BAS controllers.

Key Features

• 4-20mA analog output signal compatible with standard BAS and DDC controllers
• Integrated indication for direct on-site pressure reading
• Maximum working pressure of 25 psi
• Operating temperature range of 20 degrees F to 120 degrees F
• Female 1/8-inch thread port connections for standard pressure tap fitment
• CE certified for international compliance

Compatibility

Designed as an OEM-style replacement or direct-install differential pressure transmitter for residential and commercial HVAC control systems using 4-20mA analog inputs.

Installation Notes

Installation should be performed by a licensed HVAC controls technician or instrumentation specialist. De-energize the control system and isolate the pressure source before connecting or disconnecting the transmitter. Thread connections should be made with appropriate thread sealant and tightened carefully to avoid over-torquing the port fittings. Verify the 4-20mA loop wiring and power supply polarity before powering up the transmitter.
