OPERATING & INSTALLATION INSTRUCTIONS
CE MARKED SERIES 40XXX
PLEASE READ CAREFULLY BEFORE INSTALLING
PART NUMBER:
560550-0110
ISSUE: F
INTRODUCTION
Series 40XXX are fluid pressure measuring transducers in which a four active arm Wheatstone
bridge of thin film gauges, integral with a beam structure connected to a pressure summing
diaphragm, is used to convert fluid pressures into a proportional electrical signal.
These
instruments are suitable for long, continuous arduous service when operated within the published
specifications.
Series 40XXX conform with the essential protection requirements of the EMC Directive
2004/108/EC amended by certified type testing to EN 61326-1 and EN 61326-2-3.
Series 40XXX with the CE0086 mark also complies with the requirements of the Pressure
Equipment Safety Regulations 2016 and can be used as part of a safety-related system on
Category IV pressure equipment.
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 Gems Sensors
approved cable. see APPROVED CABLE section.
All instruments conform to the appropriate specifications and/or drawings applicable and have
been subjected to relevant strict quality control procedures.

499207-0006 G1/8 bonded seal up to +200°C operation. Dowty Ref: 300-020-0967-02 Refer to Dowty for external pressure ratings. Mounting: Pressure Transducer is designed to be attached by the coupling thread only. Omni- directional. To fit, use a 22.2 mm (7/8 inch) AF spanner on the hexagon provided and apply maximum torque of 27 Nm (20 lbf-ft). -

Page 6: Warranty
The instrument may withstand some excess pressure without failure, but a change in residual output may result. If this is not excessive the instrument may be re-zeroed externally, although other changes in characteristics might occur which can only be determined by total re-calibration. Failure can also occur if the system is driven into resonance by a fast pressure pulse, even though the pulse peak is within the nominal pressure range. -
