Dwyer Series 607 Differential Pressure Transmitter 4-20mA Output

Dwyer Series 607 Differential Pressure Transmitter

Product Introduction

The Dwyer Series 607 Differential Pressure Transmitter is a precision instrument designed to measure positive, negative (vacuum), or differential pressures of clean, dry air and other non-conductive, non-corrosive gases. It converts these pressure measurements into a standard two-wire 4-20 mA DC output signal, making it compatible with most industrial control systems. Available in multiple factory-calibrated models (including 607-1, 607-3B, 607-8) with measurement ranges from 0-0.10" W.C. to 0-25" W.C., this transmitter utilizes a variable capacitance transducer with a micro-machined, ultra-thin silicon diaphragm. This design eliminates the need for epoxies or organic seals, ensuring exceptional stability, minimal drift, and resistance to overpressure, shock, and vibration. Part of Dwyer’s low-range pressure measurement solutions (alongside Series 608 and 668), it is engineered for reliable performance in demanding low-pressure applications.

Features
Precise Low-Range Measurement: Capable of measuring very low pressures, with ranges from 0-0.10" W.C. to 0-25" W.C., ideal for applications requiring fine pressure control.
Stable Performance: Utilizes a variable capacitance transducer with a micro-machined silicon diaphragm and no organic seals, ensuring exceptional stability (±0.5% of full span/year) and minimal drift.
Durable Construction: Housed in 300 Series stainless steel (NEMA 2 rating), providing protection against environmental factors and ensuring longevity in industrial settings.
Wide Compatibility: Designed for use with clean, dry air and non-conductive, non-corrosive gases, making it suitable for diverse industrial and commercial applications.
Standard Output Signal: Delivers a two-wire 4-20 mA DC output signal, enabling seamless integration with standard control systems and data acquisition tools.
Overpressure Resistance: Highly resistant to overpressure, shock, and vibration, ensuring reliable operation even in challenging conditions.
Flexible Power Supply: Operates on an unregulated 12-36 VDC power supply, adapting to various electrical setups.
Temperature Tolerance: Functions in operating temperatures from -20 to 160°F (-29 to 71°C) and is temperature-compensated between 35 to 135°F (2 to 57°C), maintaining accuracy across varying environments.
Easy Adjustment: Features externally accessible, non-interactive zero and span adjustments (±10% of full span), facilitating on-site calibration if needed.
Quick Response: Boasts a response time of 250 msec, ensuring timely measurement updates for dynamic pressure conditions.
Practical Design: Equipped with 4" barbed stainless steel pressure connections for secure tubing attachment, and weighs 14 oz (397 g) for easy installation.
