Introduction

JJF 1001-2011 "General Measurement Terms and Definitions", JJF 1071-2010 "Compilation of National Measurement Calibration Specifications" Rules" and JJF 1059.1-2012 "Evaluation and Expression of Measurement Uncertainty" jointly form the basis for formulating this specification Series specifications. Acceleration overload sensors are widely used in various fields of the national economy. There are no corresponding technical regulations in China. Combined with For the actual situation of acceleration overload sensor characteristic calibration, refer to JJF 1116-2004 "Precision Centrifugal Linear Accelerometer" "Machine Calibration Specifications" to prepare this specification. This specification is released for the first time. Acceleration overload sensor calibration specifications

1 Scope

This specification specifies the calibration items and calibration methods of the acceleration overload sensor [frequency range is (0~100) Hz] This method is suitable for calibration of acceleration overload sensor when the given acceleration change rate is less than 100m/s3.

2 cited documents

This specification references the following documents. JJF 1116-2004 Precision centrifuge calibration specifications for linear accelerometers JJF 1675-2017 Inertial technical measurement terms and definitions For dated references, only the dated version applies to this specification; for undated references, only the dated edition applies. The latest version (including all modification orders) shall apply to this specification.

3 terms

The following terms, definitions and symbols established in JJF 1675-2017 apply to this specification. An instrument capable of measuring or withstanding acceleration within a certain range. An acceleration overload sensor that will close or open under certain acceleration. Also known as acceleration overload switch. The percentage of the lateral sensitivity of the acceleration overload sensor to the sensitivity in the direction of the sensitive axis. It represents acceleration overload The quality of the sensor. 3.4 Working threshold workingthreshold The on-off acceleration overload sensor changes from one state to another (i.e. from closed to open or from off). The minimum acceleration required to change from open to closed). Also called work value. Note. When the given acceleration is greater than or equal to the minimum acceleration, the state of the on-off acceleration overload sensor will change.

4 Overview

4.1 Classification Acceleration overload sensors can be divided into two categories according to their different principles. one is the on-off acceleration overload sensor When a certain acceleration is applied to it, the acceleration overload sensor will close (the original state is open) or disconnect. Open (the original state is closed); the other type has continuous current or voltage signal output within the full measurement range. The output signal of the overload sensor is collected and processed through a data collector, and its scaling factor can be obtained by fitting. (also called sensitivity), nonlinearity, second-order nonlinear coefficient and other parameters, for convenience of description, here are called non-on-off plus Speed overload sensor. Non-on-off acceleration overload sensors can be divided into strain gauge, piezoresistive, variable capacitance and servo accelerometers. ......
