The ecoTrans pH03 can be used in connection with commercially available pH or redox single rod measuring chains and an optional Pt100 or Pt1000 resistance thermometer for temperature compensation. The measuredpH-value and/or the fitting redox potential as well as the temperaturecan be passed on to PLC or recording instrument as an industrial standard signal 0/4…20mA and/or 0/2…10V. The standard signal emissions aregalvanically separated from the measuring input. The span can be freely programmed (pH: -2.00...+16.00pH; redox: -1500…+1500mV; temperature: -10…+150°C). The temperature display can be converted from °C to °F.Apart from the two norm signal outputs there is a relay with alternate contact available for simple switching tasks. An alarm can be emitted as a long term or temporary contact, but also small control tasks will be handled via limit alarm functions (min. contact, max. contact).The switching capacity of the relay is 250VAC at a max. of 8A and ohmic load.
