Series 607D DIN Rail Differential Pressure Transmitter

Specifications - Installation and Operating Instructions

he Series 607D DIN Rail Mount Differential Pressure Transmitter senses the

T

pressure of air and compatible gases and sends a standard 4 to 20 mA output
signal. The 607D housing is specifically designed to mount on a 35 mm DIN rail
in a panel. This mounting style allows for several units to be mounted closely
together reducing required space. A wide range of models are available factory

alibrated to 0.25% full scale accuracy in ranges from the very low 0.1 in w.c. to

c

5 in w.c. The zero control is for field calibration. Units also include red/green LED

2

tatus of proper transmitter operation. Versatile circuit design enables operation

s
in 2-wire current loops.

INSTALLATION

1. Location

Select a clean, dry mounting location free from excess vibration where the
temperature will remain between 20 and 170°F (-7 and 77°C). 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.

2. Position

A vertical position, with pressure connections pointing down, is recommended.
That is the position in which all standard models are spanned and zeroed at the
factory. They can be used at other angles, but final zeroing must be done while
transmitter is in that alternate position.

Pressure Connections

Integral barbed tubing connections are sized to fit 1/8˝ (3.12 mm) or 3/16˝ (4.76
mm) ID tubing. Be sure the pressure rating of the tubing exceeds that of the
operating ranges.

designed for 120 or 240 volts AC line operation. Electrical connections are made to

Wire Length

The maximum length of wire connecting transmitter and receiver is a function of wire

ize and receiver resistance. Wiring should not contribute more than 10% of the

s

eceiver resistance to total loop resistance. For extremely long runs of wiring (over

r

000 feet), choose receivers with lower resistance to minimize size and cost of

1

onnecting leads. Where wiring length is under 100 feet, wire as small as 22 AWG

c
can be used.

2-Wire Operation

n external power supply delivering 16 to 32 VDC with minimum current capability of

A

0 mA DC (per transmitter) must be used to power the control loop. Shielded two wire

3

able is recommended for control loop wiring. If grounding is required, use the

c

egative side of the control loop after the receiver. It is not necessary to observe

n
polarity of control loop connections.

Wiring Diagram

Calibration Check

Each Series 607D Transmitter is factory calibrated to the range given in the model
chart. To check calibration and adjust if necessary, the following procedure should be

sed. For purposes of clarification in these instructions, range is defined as that

u

ressure which, applied to the transmitter, produces 20 milliamps of current in the

p

oop. Zero pressure is always assumed to be 4 milliamps except on bidirectional

l

odels.

m

1. With the transmitter connected to the companion receiver, insert an accurate
multimeter in series with the current loop. The multimeter full scale range should
be 30 mA or greater.

. Connect a controllable pressure source to one leg of a tee with the other two legs

2

onnected to the high pressure port of the transmitter and the third leg to an

c

ccurate test gage or manometer, in an appropriate range. The low pressure port

a

hould be vented to atmosphere. Calibration must be performed with the unit in the

s

same position in which it will be mounted.

3. Apply electrical power to the unit and allow it to stabilize for 10 minutes.

4. With no pressure applied to the transmitter, adjust ZERO control so that loop

urrent is 4 mA. Bi-directional zero pressure is 12 mA.

c

oltage Output

V

Series 607D Transmitters can be easily adapted for receivers requiring 1 to 5 or 2 to
10 VDC inputs. Insert a 249 ohm, (1 to 5 VDC) or 499 ohm (2 to 10 VDC) resistor of
the proper power rating in series with the current loop but in parallel with the receiver
input. Locate this resistor as close as possible to the input. Because resistor accuracy

irectly influences output signal accuracy, we recommend use of a precision ±0.1%

d

olerance resistor to minimize this effect.

t

MAINTENANCE

Upon final installation of the Series 607D Transmitter, no routine maintenance is
required. The Series 607D is not field serviceable and should be returned if repair is
needed (field repair should not be attempted and may void warranty). Be sure to

nclude a brief description of the problem plus any relevant application notes. Contact

i

ustomer service to receive a return goods authorization number before shipping.
