total loop resistance. The tubing or piping supplying pressure to the unit can be
practically any length required but long lengths will increase response time slightly.
#8<3=387 The transmitter is not position sensitive. However all standard models

is a function of wire size and receiver resistance. Wiring should not contribute more
than 10% of the receiver resistance to total loop resistance. For extremely long
runs (over 1000 feet), choose receivers with higher resistance to minimize the size
and cost of connecting leads. Where wiring length is under 100 feet, wire as small
as 22 AWG can be used.

An external power supply delivering 10-30 VDC with minimum current capability of
40 mA DC (per transmitter) is required to power the control loop. See Fig. A for
connection of the power supply, transmitter and receiver. The range of appropriate
receiver load resistance (RL) for the DC power supply voltage available is
expressed by the formula:
Shielded cable is recommended for control loop wiring.

After final installation of the pressure transmitter and its companion receiver, no
routine maintenance is required. A periodic check of system calibration is
suggested. The Series 626 and 628 transmitters are not field repairable and should
be returned if repair is needed (field repair should not be attempted and may void
warranty). Be sure to include a brief description of the problem plus any relevant
application notes. Contact customer service to receive a return goods authorization
number before shipping.
