Jiao Tong University Laboratory Standard Force Gauge 0-200kN 20 ton Column Force Sensor：

　　Overview: A force gauge consists of a force sensor (or force measuring ring) and a matching indicator device. When the force sensor (or force measuring ring) is subjected to force, the magnitude of the force is indicated by the indicator device.

　　The surface of the force measuring instrument and its accessories should be free of defects that affect the technical performance. The attachments are complete and cannot be replaced arbitrarily. The force measuring instrument and its surroundings should be securely placed in a sturdy specialized instrument box.

　　2. Newly manufactured, repaired, and improperly used force measuring instruments need to be calibrated twice. After the calibration, the force measuring instrument should be disassembled and transported. The time interval between the two calibrations is generally six months

　　3. Other relevant technical aspects of the force measuring instrument should meet the requirements of the corresponding technical documents (such as GUO standards, industry standards, and factory manuals).

　　4. Use and replacement of indicator instruments

　　4.1 The indicator instrument should be used and adjusted according to the factory manual and user requirements.

　　4.2 The force sensor and indicator instrument should be used together and generally should not be replaced arbitrarily. If it is necessary to replace the indicating instrument using electrical measurement, it can be replaced by another indicating instrument without the need to recalibrate the force measuring instrument, provided that the following conditions are met.

　　5.1. The unit of measurement and the type of excitation source for replacing the indicator instrument should be the same as the original indicator instrument.

　　5.2. The original and replacement indicating instruments shall have calibration certificates traceable to national standards and providing calibration results in basic units of electricity (volts, amperes). The calibration range of the replacement indicator instrument should not be smaller than the range when used together with the force gauge, and its resolution should not be lower than that when used together with the force gauge.

　　JJF1469-2014 (Calibration Specification for Strain Gauge Sensor Measuring Instruments), JJG144-2007 (Verification Regulations for Standard Force Measuring Instruments),

　　JJG557-2011 (Standard Torque Meter Verification Regulations), JJG391-2009 (Load Sensor Verification Regulations),

　　OIML-R60 (GUO International Legal Metrology Organization Technical Standard for Weighing Sensors)

　　The NIM-ZY-LS-CL-035 standard load measuring instrument testing/calibration rules, registered with the China Institute of Metrology, are the preliminary technical standards based on which the current dynamometer indicator instrument testing/calibration is carried out. They have been replaced by the JJF1469-2014 standard.
