Transmitter For PH

With the ecoTRANS pH03, a device of the successful rail-mounted measuring series ?ecoTRANS? from JUMO GmbH & Co KG, there is now a device for pH and/or redox (ORP) as well as for conductivity or ultra pure water and/or TDS available in the same device design. 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 measured pH-value and/or the fitting redox potential as well as the temperature can 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 are galvanically 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, which increases the acceptance of the device, e.g., in America and Asia. 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 250V AC at a max. of 8A and ohmic load. The device can be set to a secure, pre-defined operating status (HOLD) via a binary input. In this way it can be defined which circumstances the outputs accept in HOLD mode (min value, max value, frozen status of last measuring value, etc). This mode ensures secure operating status, e.g., during system maintenance.
