Dwyer 616KD Series 4-20mA Differential Pressure Transmitter
Product Introduction
The Dwyer 616KD Series 4-20mA Differential Pressure Transmitter is
a high-performance instrument designed for precise measurement of
differential pressure in air, non-combustible gases, and compatible
gases. Equipped with One-Touch® one-button digital calibration
technology, it simplifies installation and maintenance, eliminating
the need for traditional potentiometer adjustments or additional
calibration tools. With multiple accuracy grades (±0.25% FS, ±1%
FS, ±2% FS) and a wide range of pressure options, it caters to
diverse industrial applications, from air handling unit filter
monitoring to pharmaceutical equipment pressure control.
Features
One-Touch Calibration: Zero and span calibration at the push of a
button, saving installation time and reducing maintenance efforts.
No pressure source or extra tools are required for calibration,
streamlining on-site setup.
Multiple Accuracy Grades: Available in 616KD-A (±0.25% FS), 616KD-B
(±1% FS), and 616KD (±2% FS) to meet varying precision
requirements, ensuring suitability for both critical and standard
applications.
Stable Performance: Boasts a stability of ±1% FS/year, maintaining
consistent measurement accuracy over extended periods.
Flexible Power and Output: Supports 4-20mA output with 10-35VDC
(2-wire) or 12-26VAC (4-wire) power supply; also offers
field-selectable voltage outputs (0-10V, 0-5V, 2-10V, 1-5V) for
compatibility with diverse control systems.
Compact and Cost-Effective: Ideal for OEM applications due to its
compact design and cost efficiency, without compromising on
performance.
