SITRANS F RA110 electric flow registers

• Информационные материалы

  Область применения

  The display of the electric flow register is a universal LCD for converting the measured value and displaying the current value, total value and accumulated total. Depending on the design, the flow register can be provided with a scaleable pulse output for the total value and/or a current output of 0/4 to 20 mA.

  Дизайн

  The electric flow register is fitted with a large, extremely clear LCD (90 x 40 mm in size), where the flow and total value are displayed with seven 17 mm digits and 8 mm digits respectively. Units, time units, flow trend and device status are displayed in addition.

  The electronics is fitted in a rugged aluminium housing (IP 67) with three large keys. The alphanumeric menu structure in English or German permits simple configuring and can be used for many applications.

  Models 61, 63, 65 and 66, 67, 68 are supplied with the electric flow register already mounted on the pulser.

  Функции

  The flow register of the SITRANS F RA110 receives, e.g. from a pulser, information on the current flow. This information is converted into the flow per second, minute, hour or day using a programmable 7-digit K-factor. Conversion is also carried out for the total values and accumulated totals. The units for the flow and accumulated total are completely independent.

  The total value can be reset by pressing the "CLEAR" key twice. The accumulated total cannot be reset, and is displayed with 11 digits.

  The standard configuration displays the total value (17 mm digits) and the flow (8 mm digits) simultaneously. It is also possible to output the current value on the 17 mm digits. In this case, the total value is displayed by pressing "SELECT". The electric register has inputs for Namur sensors. Connection is possible to practically every available sensor system.

  The active and passive 0/4 ... 20 mA analog output has a resolution of 12 bits and can be connected to a load of 750 Ω .

  The pulse output can be exactly defined, e.g. to generate one pulse per 3.5 liters. The pulse lengths can be set to 1 ... 9 999 ms. The maximum output frequency is limited to 500 Hz. The transistor can switch max. 50 V DC/300 mA.

  All configuration parameters are saved in an EEPROM. The total value and the accumulated total are saved once a minute, so that only a minimum amount of information is lost in the event of a power failure.

  The SITRANS F RA110 can be ordered with powerful LED background lighting for use under unfavorable viewing conditions. The menu language of the displays can be set to German or English.
