(Details please contact: 021-31663188) remote temperature monitor models: XTRM-2215, XTRM-3215, XTRM-4215, XTRM-2210, XTRM-3210, XTRM-4210. XTRM instrument output signal directly into the computer system analog inputs, in the central control room monitor, while the instrument panel display, analog pointer instrument display or LED digital display meter. According to the user's needs, can be indicative of instruments, recording instruments, regulators, etc. are connected in series with the power output circuit XTRM instrument, the output current is proportional to the change in temperature, is used as an indication of temperature, recording or adjusted. Users can also consult individually corresponding circuit temperature by installing the select button on the front panel of the film. Two, XTRM series of multi-loop temperature remote monitoring device works: XTRM meter line wire multi-loop temperature transmitter, it is with a multi-point RTD or thermocouple sensor used in conjunction with the various production processes of solid, liquid, gas The temperature display and a remote transmitter. XTRM meter can be installed in the vicinity of the measured object, use shielded cable for each loop temperature RTD or thermocouple signal is connected to the meter separate preamp, preamp will amplify the weak signal processing changes, transported to compare Input circuit (high temperature signal selection) or selected point input circuit for signal selection. Selected loop signal, and then through the voltage / current conversion unit treatment, the preamplifier output voltage into a DC 4 ~ 20mA current signal output. If you choose 0 ~ 150 ℃ temperature range corresponds to DC 4 ~ 20mA output. Three, XTRM instrumentation applications as exemplified in cement production monitoring: (a) XTRM meter electrostatic precipitator for coal mill, a large coal storage temperature measurement First let's talk about some live instrumentation cement plant design conditions, such as coal mill electricity dust collector, dust collector at the bottom of each coal deposit. To kiln calciner for large pulverized coal storage, such equipment, in order to prevent spontaneous combustion of pulverized coal, explosion, ensure the safety of the device, it is necessary to set a plurality of temperature monitoring. Scene temperature display, tour inside the device can understand the situation; the central control room display and temperature alarm, as an important parameter management. Coal mill electrostatic precipitator, a large coal warehouse three most common field instrumentation design program: each RTD temperature sensor configuration of a two-wire transmitter, respectively, with a two-core shielded cable lead to the computer standard analog interface in the central control room monitoring. Option Two: Each RTD sensors were cited with three core shielded cable to the computer interface thermal resistance in the central control room monitoring. Option Three: four RTD sensors are connected to the site XTRM instruments, and then lead a two-core shielded cable to the computer standard analog interface, in the central control room monitoring. A common feature of the program is in front of the two measurement points for each self-contained independent circuits, there is displayed on the central control room screen, bringing the multi-cable interface and more, and no temperature display in the field, can not give Post workers a hint. 2, the program up to a transmitter site, an increase of installation and maintenance. 3, Option II saved the transmitter, but the electrostatic precipitator and ash coal mill warehouse often very far from the station shop, the signal is very weak changes in thermal resistance, long-distance transmission of information is not necessarily very reasonable. But more important is the application of computer interface circuit, not the general pressure transmitters, temperature transmitters current transmission universal 4 ~ 20mA DC standard analog interface circuit, thermal resistance is a dedicated interface circuit, expensive, poor versatility with it, making the hardware and software of a computer system is complicated to system installation, commissioning and maintenance work to bring more. 4. Comparison of the three options, Option III is the simplest. XTRM-4 with an instrument, the thermal resistance of the four temperature sensors in the field can not only display, and transmitted to the central control room monitor is only four signal point of the highest temperature, which is unique XTRM meter place. Because the operator does not need to know within the coal mill or electrostatic precipitator ash compartment temperature distribution, and need to know the maximum temperature inside the device is how much? Are beyond the critical temperature? Such as coal storage, no matter what point when the temperature is higher than 70 ℃, have high temperature alarm, temperature above 80 ℃, not only the police but also to interlock, ensure safety, sent to the scene after the alarm, but also can check the temperature of each point, determine the accident. So, the same equipment, set up a high-temperature alarm in the central control room on it. Obviously, the program is the instrument most provinces, the provincial cable, provincial computer interface design. This design scheme, at home and abroad in large and medium-sized cement plant design has been widely adopted. The above comparison, we can conclude that: If the same equipment needed to set up multiple-point temperature monitoring (eg 2 to 4:00), and the same temperature components (such as platinum resistance), the same measurement range (such as 0 to 150 ℃), is used XTRM instrument design is the most reasonable solution is to identify the most provincial investment. (B) XTRM instrument used to measure the temperature of a variety of bearings, a cement plant often have many large motors, such as raw mill motor 2440KW, 2800KW cement mill motor, there are many large fans, such as raw mill circulating fans, kiln exhaust fan, cooling fan, and so grate kiln. Workers are most concerned about their bearing temperature, there is hope in the next machine, a central control room to monitor. Such equipment is generally used as XTRM-2 type instrument. 2, a large mill bearing temperature measurement. As raw mill, cement mill, coal grinding mill feed port, the discharge port of bearings are generally equipped with two each RTD temperature sensor, generally used XTRM-2 type instrument. 3, roller press bearing temperature measurement. Such as cement grinding roller press, by 145 tons per hour of material, bearing equipped with four platinum resistance sensor, should be used XTRM-4 type instrument, when the bearing temperature T> 47 ℃ in the central control room alarm, when T> 50 ℃ alarm and interlock to ensure the safety of the device. 4, kiln roller bearing temperature measurement. Φ3.75 × 57M kiln, there are three groups supporting wheel, each supporting wheel is equipped with four platinum resistance sensor, should be used XTRM-4 type instrument monitoring. (C) XTRM instrument used to measure the high voltage of the motor winding temperature. There are many large high voltage winding cement factory motor, such as the above mentioned mills, fans, when configured with the stator motor manufacturing temperature measurement devices (two per phase), must monitor the motor is running, when the winding temperature is greater than 120 ℃ alarm. XTRM instrument also used to measure the flue gate, gear boxes and many other temperatures, not to enumerate here. Fourth, the main features of XTRM meter: 1, XTRM instrument has multiple input all the way to high-output characteristics of the election, it can simultaneously measure multiple temperature points and automatically measured points more than the highest temperature of a point value display and a standard current signal output of 4 ~ 20mA. At the same time it has the select button, users need to view the corresponding temperature measurement points through the loop button. 2, the key components XTRM instrument imported from abroad, machine design is reasonable, with high stability and reliability of long-term technological transformation project decade meter sealing performance, suitable for high temperature powder cement plant environment. 3, wide operating voltage range. Because XTRM instrument specifically set up inside a power supply unit, the range of 13 to 36 volt power supply fluctuations outside the self-adjusted to ensure that the instrument can work in harsh mining supply conditions. 4, with good resistance to RF interference. In XTRM instrument design uses a number of RFI technology, the Shanghai Inspection and Testing Instruments and Automation Systems based GB18268-2000 "measurement, control and laboratory use electrical equipment Electromagnetic Compatibility Requirements" test, 10V / m ( 80MHz ~ 1000 MHz) field strength of its range of variation of less than 0.3%. Thus it can effectively suppress RF interference, such as walkie-talkie and the like from the scene.
