Advisor A80 Temperature panel meter for resistance thermometer input u 4 digit LED display Two optional alarms with adjustable brilliance. The Advisor A80 is a panel meter which provides an accurate temperature display from a Pt100 resistance thermometer. The meter is housed in a robust enclosure and incorporates a high quality display, push-buttons and terminals to ensure many years of reliable service. For thermocouple inputs, the complementary Advisor A85 has similar features. Main application of the A80 is to display process temperature, although the instrument is equally suitable for use in laboratory and non-industrial applications. Units of display may be °C or °F, and the minimum and maximum displayed temperatures may be recalled from the front panel push-buttons. Accessories include a 4/20mA isolated output proportional to the display, and two alarms with relay contact outputs. To prevent operators being dazzled, the display brilliance is continuously adjustable from the front panel. Calibration and programming is performed via the front panel pushbuttons. To prevent accidental or unauthorised adjustment all programming functions are contained in easy to understand menus protected by a four digit user definable security code. The display can easily be recalibrated on-site using the internal references or an external temperature calibrator. Loss of power does not affect calibration as all settings are retained for at least five years after the instrument is switched off or disconnected. The front panel is a robust, easy to clean Noryl moulding sealed with a non-reflective, scratch resistant polyester membrane. All A80 panel meters have a captive neoprene gasket which provides an IP65 seal between the enclosure and the panel, thus making the instrument suitable for installation in panels which are frequently hosed down . resistance thermometer input. u Maximum & minimum display. A 4/20mA current proportional to the A80 display is obtainable from the optional re-transmitted output. This current is fully isolated and may be programmed to represent any part of the display range. Optional alarms provide two channels each with a single pole change-over contact output which may be independently programmed as a high or low trip. The alarm setpoints are adjusted via the front panel push-buttons and may be accessed from the display mode via a separate security code. Front panel LED annunciators show the status of each alarm. enclosure with easy to clean IP65 front. Reliability is ensured by an ISO9001 approved quality control system. The A80 is protected from reverse connection and overrange inputs, and incorporates extensive radio frequency filtering to comply with the European EMC Directive. Process input meters are also available, see datasheets for Advisor A70 and A75. BEKA associates Ltd. Old Charlton Rd. Hitchin, Hertfordshire, SG5 2DA, U.K. Tel.
