Automatic temperature and pressure reduction control system
Features of Industrial Instrument Control Cabinets
① All new single-chip intelligent instruments are used, including renowned industrial instrument manufacturers such as Omron, Anton, and Wanshun, both domestically and internationally.
① High precision, high stability, and high reliability; all instruments have a basic accuracy error of up to 0.5%, with no zero-point drift for continuous operation of 18 months. The instrument features automatic digital temperature compensation and automatic zero-stabilization system, ensuring accuracy across an environmental temperature range of 0~50℃.
③ High-precision full digital display with all parameters shown in bright digital numbers for clear and easy visibility.
④ High intelligence and fully automatic control allow for no manual operation, maintaining optimal adjustment in any operating condition (manual operation function is still retained).
⑤ The setting of secondary adjustment parameters, as well as the upper and lower limit alarm parameters, can be conveniently and freely modified and adjusted through the secondary instrument panel buttons.
⑥ Can store data on-site without losing information during power outages. Settings for various adjustment parameters can be locked with a password to prevent accidental misoperations.
⑦ Digital serial communication interface allows all instruments to communicate bidirectionally with computers, forming a cost-effective DCS distributed control system network.

Installation and Wiring
① The thermal control cabinet is typically wall-mounted (to minimize floor space). The back of the cabinet has four bolt holes, allowing users to securely fasten the cabinet to the wall with expansion screws with a diameter of 8mm or more. (Available upon request for ordering.)
② All instruments on the dashboard and the pressure transmitters installed on-site have passed a 72-hour aging test prior to shipment. The accuracy of all instruments (including those installed on-site) has been systematically calibrated. The user only needs to check if the instruments are loose after long-distance transportation, if the installation is secure, if the appearance is intact, if the terminal screws are loose, and if the wiring of the instruments is reliable.
③ Please refer to the respective instruction manuals for on-site instrument installation. The interfaces for thermistors and the pressure transmitter's pressure sensing disc wrapped around the condensation buffer tube have been shipped with the thermal control cabinet. Please follow the installation and welding specifications of (or the industry).
④ The connection lines for all instruments within the thermal control cabinet's instrument panel are already installed. Users only need to connect the on-site instruments according to the on-site instrument wiring diagram. It is essential to connect strictly according to the diagram. The wiring includes the power supply input line, the cable lines connecting the SX terminal blocks inside the instrument panel to the on-site detection elements, pressure transmitters, and electric actuators, which are to be laid by the user.
⑤ The control panel of the thermal control cabinet should be reliably grounded with a ground resistance ≤ 10Ω. For a safe spark system, the ground resistance of the safety grid busbar should be ≤ 2Ω.
⑥ After completing the on-site wiring, double-check all connections against the wiring diagram to ensure they are correct, to prevent damage to the instruments when power is applied. Only after confirmation of accuracy should power be supplied.
