Dwyer 607 Series Differential Precision Pressure Transmitter
(Models: 607-3, 607-4)
Product Introduction
The Dwyer 607 Series 607-3 and 607-4 are differential precision
pressure transmitters originating from the USA, bearing the Dwyer
brand and CE certification. These transmitters are engineered to
accurately measure differential, positive, or negative (vacuum)
pressures, catering to applications requiring high precision in
pressure monitoring. With a focus on reliability and performance,
they convert pressure signals into actionable data, making them
suitable for various industrial and commercial settings involving
clean, dry, non-conductive, and non-corrosive gases. Designed for
ease of installation and integration, they offer consistent
operation within specified environmental and operational
parameters.
Key Features
Precision Measurement: As differential precision pressure
transmitters, they deliver accurate readings for differential,
positive, and negative (vacuum) pressures, ensuring reliable data
for critical applications.
Durable Housing: Constructed with 300 Series Stainless Steel
housing rated NEMA 2, providing protection against dust and limited
moisture, enhancing longevity in industrial environments.
Quick Response: Boasts a maximum response time of 250 ms, ensuring
timely detection and transmission of pressure changes for dynamic
pressure conditions.
Flexible Power Supply: Operates on a 12 to 36 VDC power supply,
adapting to various electrical setups in different installations.
Easy Electrical Connections: Equipped with screw terminals for
straightforward electrical connections, simplifying integration
into control systems.
Position Versatility: Not position-sensitive, allowing flexible
mounting orientations, though avoiding upward-pointing pressure
connections is recommended to prevent moisture ingress.
Practical Mounting: Features mounting slots compatible with #8 or
#10 screws, facilitating secure attachment to mounting surfaces.
Clear Pressure Port Identification: Marked "HIGH" and "LOW"
pressure ports for correct connection—positive pressure to "HIGH,"
negative pressure to "LOW," and differential pressures with higher
pressure to "HIGH" and lower to "LOW."
Installation Guidelines
Location Selection: Install in a clean, dry area with temperatures
between -20 to 160°F, free from excessive vibration. The distance
from the receiver is limited only by total loop resistance, while
tubing length (for pressure supply) has minimal impact on accuracy
but may slightly increase response time.
Position Considerations: Though not position-sensitive, avoid
mounting with pressure connections pointing upward to prevent
condensed moisture from entering the interior. Routing tubing with
a low point before the transmitter also helps avoid moisture
issues.
Mounting Process: Secure to the mounting surface using two #8 or
#10 screws in the provided mounting slots.
Pressure Connections: Remove the pre-installed short tubing between
ports before use. For positive pressure, connect to "HIGH" port and
vent "LOW" port; for negative (vacuum) pressure, connect to "LOW"
port and vent "HIGH" port; for differential pressure, connect
higher pressure to "HIGH" and lower pressure to "LOW."
