Please Note: The Series 546 / 547 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.
GENERAL * Transducer should not be subjected to greater than the maximum allowable pressure listed on label and the operating temperature specifications. SEE OPERABLE TEMPERATURE RANGE: * Transducer should not be subjected to mechanical impact. * 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.
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).
ADJUSTMENT OF ZERO AND SPAN CONTROLS Switch and potentiometers provide continuous adjustment over the range 130% to 17% of nominal pressure range. Zero and Span controls are precisely set during manufacture and should only need 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 2.5mm A/F hex wrench and withdraw end plate.
FIGURE 1 SUPPLY VOLTAGE Non I.S: I.S: 8.5V to 40V d.c. 9.5V to 28V d.c. 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. 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.
