GEFRAN F008334 is a pressure transmitter from the MN2 series, featuring a measurement range of 0-6 bar, an M-type connection, a B07C electrical connection configuration, a 1/4" process connection, a voltage output (unspecified, but typically 0-10V or similar range), and mercury filling. The additional coding "2130X000X00" indicates the specific configuration of the product and typically includes other optional features determined according to customer requirements. The mercury filling ensures stable and reliable pressure measurement even in high-temperature and harsh conditions. The voltage output allows for direct connection to control systems operating with analog voltage signals. The "D" designation may indicate an additional detail related to the output signal type or other special functions.
