Drying Equipment Monitoring & Control Instruments

I. Overview

  The LU-MSC100 wood temperature and humidity controller integrates detection, recording, PID control and data printing, and is mainly used in heat treatment production. It has 4 PT100 RTD inputs plus instrument alarm and control outputs, with complete isolation between input and output. The first and second channels measure ambient humidity 1 and ambient (dry-bulb) temperature 1. The third and fourth channels measure ambient humidity 2 and ambient (dry-bulb) temperature 2. The instrument also records and prints data.

    Flexible data storage modes: the recording storage space is dynamically adjustable, and each channel has an independently adjustable recording interval; users can select channels and recording intervals for data storage as required. A large-capacity FLASH memory chip stores historical data, which is retained on power failure, and the internal storage time can reach 140 hours to 5600 days.

    Convenient data processing methods: connect directly to a micro printer to print data and curves for a user-specified time period; connect to a portable computer or palmtop (PAD) via the RS232 communication interface to upload real-time/historical data from the instrument directly, and analyze, archive and print the data through host computer data management software; it can also be connected to professional configuration real-time monitoring systems such as KingView and MCGS.

    Powerful display functions: extra-large numeric display, bar graph display, real-time curve display, historical curve display, alarm query, alarm status display, etc. All curve screens can be zoomed, and an intelligent fully automatic playback of historical trends is provided with time and amplitude zoom, making it extremely convenient to locate alarm points. A positioning query function is also provided, allowing direct query of data for a specific year, month, day, hour, minute and second, which is convenient and fast. A flow statistics function is available to query the cumulative flow value of any period;

    Modular design makes configuration more flexible, and different acquisition boards can be used simultaneously; the power supply and acquisition boards are designed in separate layers, and the input and output are completely electrically isolated, greatly improving the reliability of the instrument.

    It also provides a bilingual Chinese/English display interface. 

II. Technical Specifications

●  LCD: 128*64 monochrome liquid crystal display

●  Temperature measurement range:0-100°C

●  Temperature basic error:±1°C

●  Humidity measurement range:0-100%RH

●  Humidity resolution:1%RH

●  Acquisition period:0.5 s

●  Settable range of data recording interval:1 second to 4 minutes

●  Storage time:T=storage capacity/sum of the reciprocals of the recording intervals of all active channels; the more channels are enabled and the shorter the recording interval, the shorter the storage time. When the stored data is empty, the storage capacity, i.e. the total number of storage records, is 4000*504.

For example: when the stored data is empty and channels 1, 2, 3 and 4 are enabled with recording intervals of 1 s, 5 s, 10 s and 20 s respectively, then T=4000*504/(1/1+1/5+1/10+1/20)=1493333.3 s=414.8 hours=17.28 days

●  Power supply:AC220V±%10,50Hz±2Hz

●  Ambient temperature:0-45°C

●  Ambient humidity:0-85%
