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.
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.
ELECTRICAL CONNECTIONS
Shielding cabling is required. Cable shield must be attached to a reliable
earth ground. Electrical connections are made to the terminal block
located on the top of the transmitter. Terminals are marked 1, 2, 3, 4.
Determine which of the following circuit drawings applies to your
application and wire accordingly.
Wire Length
The maximum length of wire connecting transmitter and receiver is a
function of wire size and receiver resistance. Wiring should not
contribute more than 10% of the receiver resistance to total loop
resistance.
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.
