Provided is a leveling mechanism for a weighing device that facilitates horizontal leveling of the weighing device. The leveling mechanism () includes a foot piece () having a foot portion () that in contact with an installation surface and a foot piece shaft () that extends upward from the foot portion and has a male screw () on its outer periphery, a rotatable body () having on its inner periphery a female screw, a housing () for accommodating the rotatable body engaged with the foot piece, a fixing portion (S) for fixing the housing to a device case (), and a housing space () covering the housing, provided in the device case. The leveling mechanism converts a rotational motion of the rotatable body to a vertical motion of the foot piece.

For easy centralized management of measurement data and installation environmental data and user's real-time recognition through a certain type of peripheral equipment of how the installation environment affects the measured values at the site of measurement, a data logger for a measurement device includes in its structure any of the sensors for temperature, humidity, air pressure, and acceleration as an environmental sensor that detects a physical quality of an environment where the measurement device is installed, a data recording unit that records installation environmental data detected by the environmental sensor and measurement data detected by the measurement device on the basis of time, and a data processing unit that displays the installation environmental data and measurement data in whole or selectively, as numerical values or graphs of changes over time, with the time axes aligned, and includes one or more external equipment terminal connectors that exchange signals with external equipment.

Data logger for measurement device

To prevent measurement errors caused by impact including an impact load transmitted at high speed or static electricity and prevent destruction of a sensor unit due to the above-mentioned impact load. Through-holes () are formed in four corners of a pan receiver, upwardly protruding pieces () of a plate spring fixed to a bottom surface of the pan receiver are inserted into the through-holes (), and pan receiver legs are attached to the upwardly protruding pieces (). When a pan is mounted on the pan receiver, four corners of the pan are supported by the upper surfaces of gel-like cushioning bodies and the upper ends of coil springs, impact applied to the pan including an impact load transmitted at high speed is absorbed by the gel-like cushioning bodies, and the lower ends of the coil springs contact the upwardly protruding pieces () of the plate spring, so that the pan assumes a conducting state with the pan receiver via the coil springs and the plate spring, and even if the pan is charged with static electricity, the static electricity due to charging can be released to the pan receiver via the coil springs and the plate spring.
