Please Note: Series 540 / 541 / 542 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.
* In the event of fire the end user must ensure that the system pressure is vented to a safe area. * The effects of decomposition of unstable fluids 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 component in the end users system. * Pressure range must be compatible with the maximum pressure being measured.
High Temperature Pressure Measurement : Possible using a length of piping or a "syphon" to isolate the instrument from the hot media. Since there is no flow, the temperature drop along the tubing is considerable and usually a relatively short length is sufficient to bring the pressure media temperature within acceptable limits for the instrument. Alternatively a temperature isolator, part number GA33, can be fitted (G¼ connection only).

MAINTENANCE Routine Inspection: Not required except for periodic inspection of the cable and molding to ensure that these are neither damaged nor softened by incompatible liquid. If Malfunction Occurs: Isolate the free end of the cable and measure the input and output resistance. If vastly different from specification, either lower or higher, the strain gauge is damaged and the instrument will have to be replaced.
CAUTION CARE MUST BE TAKEN NOT TO TOUCH THE PRESSURE SENSITIVE DIAPHRAGM WHILE CLEANING THE PRESSURE PORT. FAILURE TO OBSERVE THIS PRECAUTION CAN CAUSE IRREPARABLE DAMAGE. WARRANTY The Company warrants its products to be free from defects in material and workmanship in normal use and service for a period of two years from date of shipment. The Company reserves the right and option to refund the purchase price in lieu of repair or replacement upon evaluation of the returned original part.
WARNING * IF INSTRUMENT IS SUBJECTED TO +400°C PLUS Some instruments use Viton sealant.
