Setra System Model 522 - Manual (Page 3)

Please Note : Series 522 / 526 are designed and manufactured in accordance with sound engineering
practice as defined by the Pressure Equipment Directive 97/23/EC. This product must not be used as a
“safety accessory” as defined by the Pressure Equipment Directive, Article 1, Paragraph 2.1.3. The CE
Mark on the unit does not relate to the Pressure Equipment Directive.
INTRODUCTION
The Series 522 / 526 pressure transducers use molecularly bonded high output strain gauges to provide
100mV output for full range pressure, when used with a 10V d.c. power supply.
Series 522 / 526 high output pressure transducers and transmitters are fitted with an ASIC providing
various optional (at time of order) voltage outputs, and a 4-20mA current output capable of being used
in control and indicating loops without further amplification.
Series 522 / 526 with the CE Mark conform with the essential protection requirements of the EMC
Directive 89/33/EEC amended by certified type testing to EN 50082-2 and EN 50081-1.
HAZARDOUS PRODUCTS
The Consumer Protection Act of 1987, Section 6 of the Heath and Safety at Work Act 1974 and the
Control of Substances Hazardous to Health Regulations 1988 require that we advise recipients and
users of our products of any potential hazards associated with their storage, handling or use.
The products which our Company supplies may be classified as Electrical, Electro-Mechanical and
Electronic equipment.
These products are tested and supplied in accordance with our published specifications or individual
special requirements that are agreed in writing at time of order. They are constructed so as not to affect
adversely the safety of persons and property when properly installed, maintained and used by qualified
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 described in these instructions have been met. For units supplied without
a cable assembly connection to the transducer must be accomplished using Setra
Systems approved cable. See APPROVED CABLE section.
