On the control panel of the charger, the engineer was to measure dozens of entanglements of electrical currents and picked a small device that could go straight into the flow welding; and went to the storage cabinet, where the mother row ran for thousands of entanglements and replaced her hand with a square module with holes. Also hall's current sensor, why does walt jwdc-hs01 and jwdc-hs02 look so different。
Let's start with the hs01 on the board. It is installed with a printboard welding system, a primary conductor, which is integrated with the sensor, 5 volts of electricity, a rated range of 10 to 120 am, an output voltage signal of 1 per cent below 25 degrees centigrade, and is relaxed to 3. 8 per cent at 105 degrees celsius; and a bandwidth-by-mass slotting of 280 khz for 10 to 16 slots and 20 to 50 slots, down to 90 khz for 80 to 120 slots. The main electricity flow is carried from the conductor that the device carries, the signal line and the needles are welded into the printing board, which the entire plant can paste with other elements and save the man-made assembly suitable for the compact and automated board and the power panel。
The other hs02 is a perforated module installed on the panel, with a perforated hole, 5 volts of power, rated at 100-1500, in the middle of the shell, with the same output of a voltage signal, 2% accuracy at 25°c and a bandwidth of 40 khz. The main circuit does not have to be cut off, does not have to make connections, does not introduce additional exposure resistance, is mounted on the panel and is intended for use by several hundred to thousands of mother lines。
Both of them are the old logic of the opening of hole: the electrical currents in the heart-trapped circuits produce magnetic fields around them, the magnetic sensitivity elements sense the magnetic field in the air gap, the internal circuit converts it linearly into a voltage output, measures electrical isolation between the circuit and the main circuit, and does not link to the power route。
The cold knowledge is here: the form of installation determines how much current it can measure, which in turn limits bandwidth and precision. To catch thousands of accelerators, the perforate and internal magnetic circuits must be large, with large magnetic cores and large apertures, with increased parasitic parameters, slower magnetic field construction and receding, with a natural drop in bandwidth, and a small quantities of 280 khz, leaving only 40 khz. Magnetic cores at large apertures are even more difficult to control and precision is reduced from 1 per cent to 2 per cent, with further discounts at high temperatures。
There are two more details of the use of the ring structure. A uniform 5-volt power supply, voltage signal output, which can be delivered directly to the master-controlled modulus, with simple perimeters; however, open-ring measurements rely on the stability of zero points and sensitivity, magnetic cores and magnetic sensitivity elements will drift with temperature, and the accuracy of the high-temperature slot will be significantly eased, and the thermostat will have to be calibrated according to the actual temperature range. The primary conductor for welding is to be heated by welded copper cortex, which cannot be saved; the main electricity for piercing is less than the body of the device, and hardly bears the burden of the main return heat, but it is to ensure that it is mid-lined and secure, and that the module cannot be moved while the mother is vibrating。
So the selection is not the one with the largest scale, but rather the main circuit, which is to be followed: electricity is in the panel, welding is to be automated, welding is to be selected with an integrated conductor; it is to be run by a parent, cannot be cut off, and the piercing module is to be selected. Form, range, bandwidth, precision, four of which are bound together with the same set of physics。
