Thermotechnique to quickly and easily check the resistance and temperature values of millivolts and temperature values
2012-3-31 14:15:43

采用16位单片机作为CPU,集最新大规模数字转换集成电路和大屏幕液晶显示技术于一体,具有输出、测量、手册和24VDC配电功能,且四项功能可同时工作,并配备超大容量可充电电池供电,携带方便,是热工仪表行业人员在现场检修、调试的极佳配置; 小巧、便于携带和手持, 坚固、可靠,背面的支撑架和挂钩孔适合现场使用。 Thermal Engineering Collection adopts 16-bit single-chip microcomputer as CPU, integrates the latest large-scale digital conversion integrated circuit and large-screen liquid crystal display technology, and has output, measurement, manual and 24VDC power distribution functions. Capacity rechargeable battery-powered, easy to carry, is an excellent configuration for field instrumentation personnel to overhaul and debug on the spot; compact, easy to carry and hold, sturdy and reliable, the support frame and hook holes on the back are suitable for field use. Large display screen, measurement, output, and thermal manual data can be displayed simultaneously. Can measure voltage, current, frequency, thermocouple, platinum resistance, copper resistance and common resistance. Thermal engineering can output voltage, current, millivolt, frequency and other signals 24V DC power distribution output to provide loop power for the transmitter. The thermal manual realizes the quick mutual inquiry of the resistance value and the temperature value, the millivolt value and the temperature value, and the quick inquiry of the pressure and density, temperature and density of the saturated steam. With backlight control function to meet night use.
Edit this paragraph III. Technical parameters ⒈ Output signal ① Current: 0 ~ 24mA DC accuracy: ± 0.05% FS resolution: 1μA RL ≤400Ω RL × IL ≤8V ② Voltage: 0 ~ 6V DC accuracy: ± 0.05% FS resolution : 0.1mV RL ≥10KΩ ③ Millivolt: 1 ~ 120mV DC Accuracy: ± 0.05% FS Resolution: 1μV RL ≥20KΩ ④ Frequency: 0 ~ 5000Hz TTL level rectangular wave resolution: 0.1Hz

The manual of thermal engineering can realize the quick mutual check of resistance value and temperature value, millivolt value and temperature value, and the quick query of pressure and density, temperature and density of saturated steam. With backlight control function to meet night use.

主要是为了现场热工仪表及系统的校验维护而设计,仪表提供完善面实用的功能,操作简单。 The thermal engineering collection is mainly designed for on-site thermal instrumentation and system calibration and maintenance. The instrumentation provides comprehensive and practical functions and simple operation. The meter uses a single chip microcomputer as the CPU. It integrates the latest large-scale digital conversion integrated circuit and large-screen liquid crystal display technology. It has output, measurement, manual and 24VDC power distribution functions. The four functions can work at the same time. And the corresponding ITS-90 standard value (thermal resistance, thermocouple). And equipped with a large-capacity rechargeable battery, easy to carry, can easily complete the maintenance and calibration of industrial field thermal instruments (sensors, transmitters, display instruments, control systems)
