摘要： In electronic balance, an analog computation portion determines at least a differential control signal according to an amount of displacement of a beam. A digital computation portion determines at least an integral control signal is determined by after the amount of displacement of the beam is digital-converted. The control signal component determined by the digital computation portion is analog-converted. Thereafter, a synthetic PID control signal is determined by being synthesized from a resultant signal and the control signal component, which is determined by the analog computation portion. Subsequently, a coil current based on the synthetic PID control signal is passed through the coil. A weight value is obtained according to the control signal component determined by the digital computation portion.

摘要： [Problems] To obtain a stable measurement result in both a measuring-out mode and normal mode, and to obtain a weight value eliminating the influence of convection in the windshield.[Means for Solving Problems] An electronic balance with a windshield 51, the windshield surrounding a measuring pan 53 and having an openable/closable door 52, for averaging measurement data in a response time and obtaining a weight value based on it, the electronic balance including: a door open/close detection sensor 3 for detecting an open/close of the door 52; and a mode changer for switching the measurement mode between a measuring-out mode in which the response time is relatively short when the door 52 is open, and a normal mode in which the response time is relatively long when the door 52 is closed. In addition, in a convection time measurement mode, a convection time period since the door is closed with no sample on the measuring pan 53 until the fluctuation of the measurement data is settled down within a predetermined range is measured and memorized. After the memorized convection time has passed after a sample was put on the measuring pan 53 and the door 52 was closed in a normal measurement mode, the measurement data is averaged in a predetermined response time and the weight value is calculated.

摘要： An electronic balance includes a load transmission mechanism for receiving an object to be measured, a magnetic field generator having a force coil for generating magnetic field, and a balance beam connected at one end to the load transmission mechanism and disposed adjacent to the magnetic field generator with a fulcrum interposed between a portion connected to the weight section and the magnetic field generator. An electromagnetic force generated by supplying current to the force coil is applied to the balance beam to obtain a weight of the object from the current flowing through the force coil in equilibrium with the load. A damper is attached to the balance beam to control vibration in at least one of a longitudinal direction of the balance beam and a horizontal direction perpendicularly intersecting therewith.

摘要： Disclosed is an electromagnetic-force-balancing-type electronic balance having a magnetic circuit which includes a yoke 4, a first permanent magnet 1, a pole piece 3, a second permanent magnet 2 and a cover 5. A connection member 7 made of a magnetic material is disposed in an air-gap region included in the magnetic circuit. The connection member 7 may be disposed between the second permanent magnet 2 and the cover 5 or between the cover 5 and the yoke 4 to facilitate assembling operations. Alternatively, first and second gap-defining members 8, 9 made of a non-magnetic material may be disposed, respectively, between the first permanent magnet 1 and the yoke 4 and between the second permanent magnet 2 and the cover 5, to provide symmetric properties in magnetic sub-circuits so as to counteract an imbalance in hysteresis characteristic. The present invention can suppress adverse influences of a magnetic resistance caused by an air gap existing in the magnetic circuit of the electronic balance.
