1.3 Structure Overview

Accelerator&Temperature Sensor is composed of waterproof housing, circuit board, Accelerator sensor, temperature sensor and antenna. The shell is made of aluminum alloy die-casting. After high-speed shot blasting, the surface is sprayed with high-voltage electrostatic plastic, which is strong anticorrosive and can be used in all kinds of harsh environments. All external ports are waterproofed to ensure that the equipment operates in an airtight environment. It has High protection structure and optimized maintenance operation.

The Accelerator&Temperature Sensor shall be installed by bracket with 90-degree i-type or 45-degree inclination. The bottom end of the bracket shall be glued to the monitoring equipment with metal structure adhesive. The top end shall be connected to the bottom of the Accelerator&Temperature Sensor with M3 stainless steel bolts. The temperature sensor is magnetic adsorption probe, which is directly adsorbed on the equipment when used. The antenna is an omnidirectional rotatable antenna.

4.Application

4.1Open the cover of the sensor, fix the battery with a tie, plug in the power plug, and the indicator light flashes to indicate successful startup.

4.2Bind the equipment monitoring points in the system and enter the equipment number.

4.2During the use of the monitoring terminal, the terminal battery shall be replaced according to the battery power and signal strength displayed by the system.

4.3The on-site user shall understand the performance of the monitoring terminal. When abnormal operation is found, it shall be inspected under the guidance of our engineer. It is strictly prohibited to open the box cover of the monitoring terminal under the working state of the production line, and it is strictly prohibited to disassemble the equipment for maintenance without authorization.

5.Sensor Maintenance

5.1 Maintenance personnel must attend on-the-job training class to understand the performance of Accelerator&Temperature Sensors and know the requirements for use.

5.2 Regularly clear the shell of Accelerator&Temperature Sensors to improve the heat dissipation performance of Accelerator&Temperature Sensors. Water or cloth wipe are allowed.

5.3 Check the oil stain of the housing, whether it has been impacted by foreign bodies, whether the fixing bolt is loose, if so, it should be strengthened or replaced in time.

5.4 The battery quantity shall be changed in time according to the prompts of the system. It is strictly prohibited to open the equipment for replacement when the production line is working and operate in strict accordance with the instructions when disassembling.

5.5 The Accelerator&Temperature Sensor is explosion-proof and waterproof. The sealing part should not be dismantled or opened frequently, otherwise the explosion-proof performance of the Accelerator&Temperature Sensor will be affected.
