這種基于微處理器的調(diào)高控制提供了4個文件/ 24步的程序功能或易于使用的非調(diào)高設置點操作。增加操作包括四個文件，每個文件有六個步驟。編程選項包括ramp - rate或基于時間的配置文件，保證浸泡偏差，程序循環(huán)，以及在斷電后的程序狀態(tài)選擇。文件可能與創(chuàng)建一個24步程序有關。也允許用戶輸入小的控制參數(shù)的自動設置。在自動調(diào)優(yōu)模式下，暴利系統(tǒng)通過“學習”序列自動設置PID參數(shù)(比例帶寬、重置/積分和速率/衍生)。主要的模擬輸入是熱電偶。背板有一個九針串口，用于與PC機通信。二次輸出可用于冷卻，以及4 - 20ma的溫度記錄和RTD輸入的再傳輸輸出。信息存儲在非易失性存儲器中。

RAMPTROL

This microprocessor-based ramping control provides four-file/24-step program capability or easy-to-use non-ramping set-point operation. Ramping operations include four files with six steps each. Programming options include ramp-rate or time-based profiles, guaranteed soak deviation, program looping, and program status selection after power outage. Files may be linked to create a single, 24-step program. Also allows automatic setting of control parameters with little user input. RampTrol automatically sets the PID parameters (proportional band, reset/integral, and rate/derivative) through a “learning” sequence in the auto-tuning mode. The primary analog input is a thermocouple. The back panel features a nine-pin serial port for communication with a PC. A secondary output is available for cooling, along with a 4-20ma retransmit output for temperature recording and an RTD input. Information is stored in non-volatile memory.
