Heat display paperless recorder Shanghai Instrument Factory ZW200RH intelligent paperless recorder intelligent temperature inspection instrument

1、 Instrument Overview:

Heat display paperless recorderEquipped with RS-232C or RS-485 communication interface, supporting remote configuration and data management of upper computer; The communication distance of wired network through repeater can reach 5km, and the baud rate of Zui is 19.2K. Ultra remote monitoring and management can also be carried out through MODEM dialing, GSM mobile SMS, GPRS mobile communication, or wireless data transmission methods. The use of a handheld computer (PDA) allows for direct configuration and data management. Equipped with a built-in printing driver, it can directly connect to a micro printer to print historical data and curves of a time period.

2、 Display function:

Heat display paperless recorderIt has powerful display functions, including high-precision bar graph display, real-time trend curve display, historical curve recall, over limit alarm, alarm status display, and intelligent automatic playback function for historical trends. It is extremely convenient to search for alarm points and also provides positioning playback function, which directly queries data of a certain year, month, day, hour, minute, and second, making it convenient and fast. It can simultaneously display the set value, measured value, output valve position, and manual and automatic signs.

3、 Applicable occasions:

Heat accumulation paperless recorderWith various traffic calculation models. It can be equipped with various sensors such as vortex street, electromagnetic flow meter, differential pressure transmitter, etc. With batch control function. It can be applied to various industrial sites such as metallurgy, petroleum, chemicals, building materials, papermaking, food, pharmaceuticals, heat treatment, and water treatment.

4、 Performance characteristics:

1. With various traffic calculation models. It can be equipped with various sensors such as vortex street, electromagnetic, orifice plate, bend pipe, etc.

2. The small flow replenishment metering function, combined with real-time monitoring and recording function, effectively prevents theft of gasoline.

3. Provide cumulative heat shift reports, daily reports, monthly reports, and annual reports.

4. When the temperature sensor malfunctions, it will automatically use the set temperature to calculate the compensation amount.

5. It has a power failure recording function, which records the instrument's power on and power off time, displays the cumulative power off time, and prevents measurement errors caused by power outages.
