2 System versions The compact version combines a ph sensor and an electronic module with a display in an IP65 enclosure. The access to the output terminals are provided via two cable glands or a cable plug EN The panel-mounted version consists of an electronic module 8205 integrated in a front-cover. The associated separate ph sensor is Type The output signals are provided on a terminal strip. The wall-mounted version consists of an electronic module 8205 in an IP65 enclosure. The associated separate ph sensor is Type The output signals are provided on a terminal strip via cable gland. Bürkert designed fitting ensures simple direct installation of the Bürkert transmitter into pipes from DN 15 to DN 200. Operation and display Customized adjustments, such as measuring range, engineering units can be carried out menu-supported on site via a multi-lingual display. The operation is classified according to three levels. Main Menu - ph - temperature - output current - electrode voltage - HOLD function - ph electrode calibration Calibration Menu - language - temperature unit - measuring range 4-20 ma - relay parameter definition - selection of temperature compensation (Pt1000 or manual) - display or not of electrode voltage in main menu - filter selection Direction upwards in menu Choice of digit values Steps from 0 to 9 Accept of chosen parameter or adjusted value Test Menu - Offset - Span - temperature adjustment - simulation of ph Direction downwards in menu or sideways for digit selection Relay 2 LED (contact closed) Relay 1 LED (contact closed) p. 2/12

3 Compact ph transmitter Type 8205 The sensor component consists of a replaceable combination ph-electrode, screwed into the sensor housing. The measured signal is conveyed to the transmitter via a coax plug. The Pt1000 for automatic temperature compensation is a standard feature in the sensor housing. The transmitter component converts the measured signal, displays the actual value and computes the output signals. Pressure / temperature chart Pressure (bar) 7 PVDF Metal PVC + PP PVC Temperature ( C) Principle of operation PVDF PP The most important part of the ph transmitter is the ph electrode with its ph selective glass membrane. When the electrode is immersed into the solution, an electrical charge caused by ions (H+) generates a cell voltage between the glass membrane and the solution. This electrical voltage is measured with reference to a reference electrode, located around the ph glass electrode. The cell voltage of the combination electrode is directly proportional to the ph value. The transmitter functions in a two wire circuit (without relay) or three wire circuit (with relays - limits values freely adjustable) and requires a power supply of V DC. A ma standard signal proportional to the ph or to the temperature ( C) is available as output signal.
