Type S0 INSERTION Adapter/Fitting Type 880-DF Diaphragm valve with control unit Type 030 On/Off Diaphragm valve Type 8644 Valve islands Type 86 Universal process controller econtrol PLC The Bürkert compact meter Type is designed for measuring the conductivity of fluids. The conductivity meter consists of a sensor, plugged-in and pined to the transmitter (with removable display). The sensor comprises a cell with two electrodes and a Pt00 temperature probe. The sensor itself is available with three different cell constants C, these with C=0.0 or 0. are fitted with stainless steel electrodes and those with C=.0 are fitted with graphite electrodes. The conductivity meter can operate independent of the display but it will be required for programming the device and also for visualizing continuously the measured and processed data. The device Type is available: - with three fully programmable outputs: two transistor and one -wire 4 0 ma current outputs - with four fully programmable outputs: two transistor and two 3-wire 4 0 ma current outputs. The transmitter converts the measured signal, displays different values in different physical units (if display mounted) and computes the output signals, which are provided via one or two M fixed connectors.

The load carriers are ions (E.G. dissolved salt or acids). In order to measure conductivity two electrodes are used which are set at a fixed distance apart and with a known specified surface. An AC voltage source is connected to the electrodes. The measured current is a direct function of the conductivity of the solution. The conductivity meter is a two-wire device (single meter version) or a three-wire device (dual meter version) and requires a power supply of 4 V DC (single meter version) or V DC (dual meter version) up to 36 V DC. The conductivity meter can be fitted with 3 different sensors with cell constants 0.0, 0. or.0 cm C=0. C=0.0 C= C=.0 The sensor is selected according to the measuring range and medium by using the table opposite. C=0.0 C= ms/cm -- ultra-pure pure industrial sewage p. 3/7

4 Installation The conductivity meter can be installed into any adaptor with G ½ external threaded sensor connection by just fixing the main nut. Select and install the required adaptor onto the pipe according to specific requirements of the sensor and material (temperature and pressure). For mounting on a tank or direct mounting on a pipe (DN0 and DN), an adaptor with a G ½ external threaded sensor connection must be used. Install cautiously the device on the fitting. It can be installed in any position (prefer A mounting to install a with sensor C=0. or C=0.0 cm- ). In order to get reliable measurement air bubbles must be avoided. Please ensure that the mounting location provides a continuous and complete immersion of the sensor in the flow stream. A The device must be protected from constant heat radiation and other environmental influences, such as direct exposure to sunlight.
