ELECTRICAL INSTALLATION
All types include suppression devices providing transient protection to EN 61000-4-2 and EN 61000-
4-4.
For all types conformity with the requirements of the CE mark only applies when
connection is made with Setra Systems approved cable, See APPROVED CABLE
section, and the screen of that cable is connected to a reliable grounding point at the
instrumentation end.
APPROVED CABLES
Setra Systems uses cable comprising 7 color-coded wires, with a central vent tube, enclosed by an
aluminium/polyester shield where the shield is in contact with a separate drain wire. The outer sheath
material is Polyurethane (immersible, 122°F (+50°C)). Alternative outer sheath materials available on
request for harsh environments.
OPERATION
Having installed the transducer as instructed it is ready for use. The transducer should not be removed
while the system is at pressure
.
Before applying power, check that the correct polarity and excitation
levels are being applied. See ELECTRICAL REQUIREMENTS.
Cable Version: -4°F to +122°F (-20°C to +50°C)
Connector Version: -13°F to +185°F (-25°C to +85°C)
Process Media: -40°F to +212°F (-40°C to +100°C)
OPERATIONAL LIFE:
Limited to 10 million full scale cycles.
CALIBRATION
Transducers are calibrated to the range requested at time of order. Gauge datum vented to atmosphere
via the electrical connection
ADJUSTMENT OF ZERO AND SPAN CONTROLS
Switch and potentiometers provide continuous adjustment over the range 110% to 32% of nominal
pressure range. (See Table below)
Zero and span controls are precisely set during manufacture and should only read adjustment if there is a
change in the required pressure measurement.
Access to these controls is provided by means of a removable end plate. Remove the 3 retaining screws
using 2.5m A/F hex wrench and withdraw end plate.
Caution: Care should be taken in withdrawing end plate so as not to disconnect internal plug.
