JJG (Zhejiang) 68-2003 "High-temperature load sensor Zhejiang Province local metrological verification procedures" (hereinafter referred to as "Procedures"), jointly drafted and formulated by Zhejiang Weighing Apparatus Management Office and Zhejiang Yuyao General Instrument Company, and managed by Zhejiang Weighing Apparatus Responsible for explanation.
The localized production of load cells in high temperature environments has only been developed in recent years. Zhejiang Yuyao General Instrument Co., Ltd. is one of the first manufacturers to achieve localized design and production of high temperature load cells.
In order to standardize the production and calibration of localization of high-temperature sensors, Yuyao General Instrument Co., Ltd. has invested a large amount of manpower and material resources since 1998, repeatedly conducting material testing, temperature testing, pressure testing and processing assembly process testing, and summing up experience from the testing process. Summarize the regularity and standardize the production of high temperature sensors. According to the production practice experience, draft calibration specifications are drafted and raised to the verification procedures.
During the drafting of the "Procedures", the engineering and technical personnel of the Zhejiang Weighing Apparatus Management Office went to the production site several times, and together with the engineering and technical personnel and technical workers of the General Table Company of Yuyao City, passed the test for more than one year - drafting - Modification - test - re-modification - the process of re-testing, repeated revisions, repeated argumentation, trial and error, several easy drafts, and finally become a positive result;
The contents of the Regulations apply to pull-type, compression or tension-for-loading for force measurement or weighing after new manufacture, use or repair, and 100 °C ≤ resistance strain load cell with temperature ≤300 °C Verification.
The "Procedures" provides detailed descriptions and regulations on the technical performance index requirements, verification conditions, verification items, verification methods, verification cycles and verification results of high temperature load sensor products.
The issuance and implementation of the "Procedures" provide regulations and technical guarantees for the quality assurance and verification of high-temperature sensors domestically produced products, and will greatly promote the development of manufacturing technology and application technology for high-temperature sensors for special environments.

Piezoelectric Buzzer For External Drive
The piezoelectric transducers (for External Drive) produce exceptional sound output and efficiency all while meeting each customers unique performance requirements. Piezo transducers are constructed without magnets, instead they create sound mechanically via the piezoelectric effect. Our piezo transducers are not equipped with a built in drive circuit. This provides our customers with the flexibility of designing their own circuitry to meet their specific needs. The advantage of using an external drive circuit is that the piezo transducers can output sounds at multiple frequencies. Full bridge circuits ramp up SPL for more peak-to-peak voltage, making our piezo transducers a high output solution.
