Dwyer 616KD-B-06 micro differential pressure gauge transmitter high accuracy ±0.25% FS 4-20ma 0 to 140°F

The Series 616KD One-Touch® Differential Pressure Transmitter senses the pressure of air and compatible gases and sends a standard 4 to 20 mA or optional voltage output signal. A wide range of models are available factory calibrated to specific ranges. A single push button properly adjusts both zero and span. New enclosure enables the 616KD to be mounted on a 35 mm DIN rail either via its side or back DIN rail clips.

INSTALLATION

Select a clean, dry mounting location free from excess vibration. Distance from the receiver is limited only by total loop resistance. See Electrical Connections below. The tubing supplying pressure to the instrument can be practically any length required, but long lengths will increase response time slightly.

Specification

Pressure Connections

Two integral barbed tubing connections are provided. They are dual-sized to fit both 1/8˝ and 3/16˝ (3.12 and 4.76 mm) ID tubing. Be sure the pressure rating of the tubing exceeds that of the operating ranges.

FEATURES

• Simple calibration push-button sets back zero and span, saving time installing and over the service life
• Cost effective and compact device suitable for OEM applications where space, simplicity, and value are key
• Ranges and accuracy selection cover a wide range of applications minimizing components and determining standardizing on design
• Optional 1/8" NPT process connection allows for use with metal barbed fittings or compression fittings for use with metal tubing

SERIES 616KD DIFFERENTIAL PRESSURE TRANSMITTER

One-Touch® Digital Push-Button Calibration Technology, ±0.25, ±1, or ±2% Accuracy

The Series 616KD Differential Pressure Transmitters with One-Touch® Digital Push- Button Calibration Technology are designed for simplicity, making them the ideal choice for installers and maintenance professionals. These instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instruments during calibration. With a single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources or separate calibration devices are necessary.

NIST CALIBRATION available in Product Configurator.

Voltage Units (0 to 5 or 0 to 10 V)

An external power supply delivering 16 to 35 VDC or 20 to 28 VAC with minimum current capability of 16 mA DC (per transmitter) must be used to power the control loop. Connect terminals 3 & 4 to select the 0 to 5 V output mode. Leave terminal 4 disconnected to select the 0 to 10 V output mode. See Figure A for connection of the power supply, transmitter and receiver

Zero Adjustment

Transmitter should be zeroed at the temperature it is to be operated at. A single push button is provided to zero the transmitter. Span is factory calibrated to the range specified on the label. There is no user span adjustment necessary

ELECTRICAL CONNECTIONS

Do not exceed specified supply voltage ratings. Permanent damage not covered by warranty will result. This unit is not designed for 120 or 240 volts AC line operation
