Operating & Installation Instructions
Series 355X
Please read carefully before installing
INTRODUCTION
Series 355X high output pressure transducers and transmitters are tted with an Asic providing various op-
tional (at time of order) voltage outputs, and a 4-20mA current output capable of being used in control and
indicating loops without further amplication.
Series 355X with the CE Mark conform with the essential protection requirements of the EMC Directive
2004/108/EC by certied type testing to BS EN61326-1:2006 and EN61326-2-3:2006.
Series 355X with the CE0086 mark also complies with the requirements of the Pressure Equipment Regu-
lations 1999 and is classed as a safety accessory and can be used as a safety-related device on Category IV
pressure equipment. No other product should be used as “Safety Accessories”as dened by the PED Article
1, Paragraph 2.1.3.
HAZARDOUS PRODUCTS
The Consumer Protection Act of 1987, Section 6 of the Health and Safety at Work Act 1974 and the Control of
Substances Hazardous to Health Regulations 1988 require that we advice recipients and users of our prod-
ucts of any potential hazards associated with their storage, handling or use.
The products which our Company supplies may be classied as Electrical, Electro-Mechanical and Electronic
equipment.
These products are tested and supplied in accordance with our published specications or individual special
requirements that are agreed in writing at time of order. They are constructed so as not to aect adversely
the safety of persons and property when properly installed, maintained and used by qualied personnel, in
the applications for which they were designed and manufactured.
Conformity with the requirements of the CE mark only applies when the installation conditions de-
scribed in these instructions have been met. For units supplied without a cable assembly connection to
the transducer must be accomplished using Setra’s approved cable. See APPROVED CABLE section.

GENERAL
• Transducer should not be subjected to greater than the maximum allowable pressure (P.S.)/Temperature (T.S.) as dened on the transducer label.
• Transducer should not be subjected to mechanical impact.• In the event of re the end user must ensure that the system pressure is vented to a safe area.• The eects of decomposition of unstable uids should be considered by the user when placing this device in service.
• The pressure transducer has no means of draining or venting, this must be performed by another compo-
nenty in the end users system.
• Pressure range must be compatible with the maximum pressure being measured.• Pressure media must be compatible with the transducer/transmitter wetted parts listed in these instruc-
tions.
• Liquids must not be allowed to freeze in the pressure port.• The gasket must be tted under the electrical connector (mini-din only).• Supply voltage must not exceed the value stated on the unit label.MECHANICAL INSTALLATION
Mountaing: Pressure Transducer is designed to be attached by the coupling thread only. Omnidirectional,
self supported directly into the pipework. Use a 22mm spanner on the hexagon provided to apply a maxi-
mum torque of 15Nm. The customer must ensure that the pressure seal is suitable for the application. If in
doubt, please contact Setra Systems, Inc.
ELECTRICAL INSTALLATION
All types with the CE Mark include suppression devices providing EMC protection to EN61000-4-2, EM 6100-
4-3, EN 61000-4-4 and EN 61000-4-6. Conformity with the requirements of the CE Mark only applies when
connection is made with Setra’s approved cable. See Approved Cable section, and it connected as shown
below.
APPROVED CABLE
Setra Systems, Inc uses cables comprosing 2, 3 or 4 colour-coded cores, enclosed by an aluminised polyester
screen where the screen is in intimate contact with a seperate drain wire. The outer sheath is chrome PVC
and overall diameter is approximately 4mm.

OPERATION
Having installed the transducers as instructed, they are ready for use. The transducer should not be removed
whilst the system is at pressure. Before applying power, check the correct polarity and excitation levels are being applied. See Table 1 for electrical connections.
CALIBRATION
Transducers are calibrated to the datum requested at time of order; this can be identied by the sixth letter of the identication code as follows:
A - Absolute datum
G - Gauge datum vented to atmostphere via the electrical connector or cable
LOAD CHARACTERISTICS (4-20mA Current Output)
The total resistive load in the loop (to include all the cable resistance) can be ‘zero to 50 x (supply volts -7.5) ohms1 e.g. with a 24 VDC supply the permissible load is from zero up to 825 ohms.
OPERATIONAL LIFE
Limited to 100M cycles to maximum allowable pressure.WARRANTY
We guarantee this instrument against fault workmanship and material for a period of two years from date of
delivery. The company undertake to repair, free of charge, ex-works any instrument found to be defective within the specied period providing the instrument has been used within the specication in accordance
with these instructions and has not been misused in any way.
Detailed notice of such defects and satisfactory proof thereof must be given to the company immediately
after the discovery and the goods are to be returned free of charge to the company, carefully packaged and
accompanied by a detailed failure report. See RETURN TO FACTORY.
WETTED PARTS
316 Stainless Steel.
