AD105 dial switch type intelligent temperature transmitter Pt100, Cu50, Pt1000 input, 4...20mA output, lightning protection, anti-pulse group, anti-radio frequency interference, can effectively suppress the impact caused by leakage AD105 dial-switch intelligent temperature transmitter is an intelligent two-wire temperature transmitter that can set the measuring range through the dial switch, and also has the PC programmable function. It can accept RTD input and linearize the input signal, output 4...20mA (two-wire system) standard signal, and transmit to DCS, PLC and other system control equipment; with sensor damage, short-circuit fault signal can be Pre-setting and other features. The power supply method supplies power to the output circuit. No additional power supply is required. That is, it is a passive type. It is usually installed in the header box of the temperature sensor. The mounting hole is a circular strip design that can meet the requirements of junction boxes of different sizes. It can also pass The mounting bracket is mounted on a standard DIN rail.

AD105 dial switch intelligent temperature transmitter, in the range of adjustment, no need to supply power, but no need to access the resistance box or signal generator at the input, it is as simple as a small screwdriver, adjust the position of the dial switch , can adjust the range range; whether in conjunction with the use of sensors, or when used in the field, can be adjusted in real time, greatly reducing the adjustment time, while also reducing the difficulty of adjustment to a minimum, and no longer need to learn Those cumbersome configuration methods; with intuitive dial switch, you can check the current set range by the position of the dial switch, this range of intuitive features, easy to understand, WYSIWYG, At the same time, the probability of errors when adjusting the measuring range is minimized.
The product uses lightning protection and anti-electric fast transient (pulse group) interference circuit design. With the lightning protection function, the lightning protection index reaches the induction lightning (≤±4000V) for 5 consecutive times without damage to the equipment to protect the connected equipment from being damaged; both the input end and output end have anti-electric fast transients (bursts) ) ±4000V interference capacity. This product can effectively prevent the damage caused by induction or the power system's internal high-power equipment start and stop, line faults, switching action, the operation of inverter equipment and welding machine on site construction and other reasons.
The product adopts a compact structure design, easy installation; the ultra-low power design of the internal circuit greatly reduces the temperature drift caused by the heat dissipation of the components when the instrument is working, improves the long-term stability of the product, and prolongs the service life; The range is easily adjusted; the measuring accuracy of the instrument is increased; the ambient temperature range -40...+85°C ensures that the instrument works properly in harsh environments.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
