F320 is most ideal in controlling production line quality. F320 is a digital indicator with DIN 96 x 48 mm size for strain gauge type sensors. It is most ideal in controlling load pressure such as in pressing, compression and caulking work; as a torque controller of a nut runner or rotary devices and in production line quality control. It is built-in with the RS-485 (Modbus-RTU protocol) that allows easy construction of a control system that is integrated with a PLC or programmable display device.
