PR 1720 FIELDBUS TRANSMITTER
The PR 1720 digital transmitter with extensive communication capabilities.
The PR 1720 transmitter comes in an IP 65 field housing. Via the option PR 1722 an optional load cell connection sub-unit up to 4 load cells can be directly connected. The digital inputs and outputs, as well as the 16 bit analogue output, which are galvanically isolated to guarantee the highest level of security. The userfriendly, menu-prompted configuration facilitates fast and easy installation. Smart Calibration feature allows the adjustment of the scale without any reference weights. When certified load cells are used the level of accuracy achieved reaches ‘Weights and Measurements’ standards. All calibration and configuration parameters are stored in an EEPROM. This gives full protection against loss of data during a power failure. Also a back-up on PC is possible
