    Type 8202 ELEMENT Description dEscRipTioN 5.1. Area of application The 8202 transmitter is intended solely for the measurement of: • the pH in clean liquids or liquids containing solids, sulphides or proteins. • or the oxidation reduction potential in clean liquids or liquids containing solids, sulphides or proteins which may present low conductivity. Thanks to two fully adjustable transistor outputs, the transmitter can be used to switch a solenoid valve, activate an alarm and, thanks to one or two 4-20-mA current outputs, establish one or two control loops. 5.2. General description 5.2.1. design The 8202 transmitter comprises: • a module for measuring process values, comprising: - a pH or Redox sensor measuring a potential difference (PD) in mV - a Pt1000 temperature sensor built in the holder of the pH or Redox sensor, measuring a resistance. • an acquisition / conversion module for the process values measured: - measured PD acquisition in mV - conversion of the measured PD into pH units (for a transmitter with pH sensor only) - acquisition of the resistance measured and conversion into temperature • a display module with browse button used to read and/or configure the parameters of the device. The display module is available as an accessory.

This operation requires 2 buffer solutions: in general a first solution with a pH of 7 and a second solution with a pH very close to that of the process value to be measured. See page 54. At the end of calibration of the pH sensor, two types of messages may be displayed: Possible Recommended Message "span" value "offset" value cause action → "Warning:Span/ 50 mV/pH < span < 53 mV/pH -60 mV < Offset < -35 mV Error in Use the correct offset out of the buffer buffer solution.
