The push-pull force gauge can be divided into:
Push-pull force meter, tension meter, tension specific testing rack, tension specific testing machine, tension testing machine, tension specific testing instrument, etc.
Among them, push-pull force meters can be divided into graphic push-pull force meters, digital push-pull force meters, pointer push-pull force meters, and tension specific testing racks can be divided into button tension testing racks, peeling force testing racks, screw racks, hand press racks, etc. Tension specific testing machines can be divided into horizontal and vertical machines, and specialized testing instruments include handheld torque meters, torque screwdrivers, torque wrenches, etc.
Function:
The NK series pointer push-pull force gauge is a small and simple thrust and tension testing instrument, with the advantages of fine design, easy portability, peak retention, and simultaneous display of two units. Widely used in industries such as high and low voltage electrical appliances, electronics, wires, hardware locks, automotive parts, lighters and ignition devices, pen making, light industry, construction, fishing gear, textiles, chemicals, machinery, and research institutions for push-pull load testing, insertion and extraction force testing, destructive testing, etc., it is a substitute product for old-fashioned tube type push-pull force meters.
1. Method of selecting a splitter
(1) Select the rated voltage drop specification of the shunt based on the mV value indicated on the dial of the ammeter (or dual-purpose ammeter) used (generally 75mV or 45mV are commonly used). If the ammeter used does not have this value, use the following formula to calculate the voltage limit of the meter, and then select the rated voltage drop specification of the shunt.
The voltage limit of the meter (mV)=current at full scale of the ammeter (A) x internal resistance of the ammeter (Ω) x 1000
(2) Select the rated current specification of the shunt according to the desired expanded current range.
(3) Connect the two current terminals of the selected shunt to the power supply and load respectively, and connect the potential terminal to the ammeter. It should be noted that the terminal polarity of the ammeter should be connected correctly, so that the range of the ammeter is expanded to the current value calibrated on the shunt.
2. Calculation method for multiple of ammeter after using shunt
For motor testing and measurement, it is often necessary to configure multiple splitters on a single ammeter to ensure the required measurement accuracy over a large measurement range. At this point, it is required that the rated voltage drop of all the splitters used be consistent with the corresponding ammeter, such as 75mV. In this way, after selecting the shunt, the full range of the ammeter is the rated current value of the selected shunt, and the multiple of the ammeter (i.e. the current per grid on its dial scale) is the rated current of the shunt divided by the total grid on the dial scale.
There are slot type and non slot type splitters used for DC current measurement. The shunt has manganese nickel copper alloy resistance bars and copper strips, and is coated with a nickel layer. Its rated voltage drop is 60mV, but it can also be used for 75, 100, 120, 150, and 300 mV.
There are several rated currents for slot type splitters: 5 A, 10 A, 15 A, 20 A, and 25 A
The rated current of non slot type splitters ranges from 30 A to 15 kA with standard intervals.
How to measure a large direct current, such as tens of amperes, or even larger, hundreds of amperes, without a large range ammeter for current measurement? This requires the use of a splitter. It is a short conductor that can be made of various metals or alloys and also connected to terminals; Its DC resistance is strictly adjusted; Connected in series in a DC circuit, the DC current passes through a current divider, generating millivolt level DC voltage signals at both ends of the divider. This causes the pointer of the meter connected in parallel to the divider to swing, and the reading is the current value in the DC circuit. The so-called shunt refers to dividing a small current to drive the meter reading. The smaller the ratio of this small current (mA) to the current in the large circuit (1A - tens of A), the better the linearity and accuracy of the ammeter reading. This is a commonly used product in electrical circuits, with lightning protection and shunt measures.
There are various specifications of ammeters, but the actual meter head is a standard millivolt voltmeter. For example, a voltmeter with a full scale of 75mV. So to measure a current of, for example, 20A with this voltmeter, it is necessary to equip it with a shunt resistor that produces a 75mV voltage drop when a current of 20A flows through it, also known as a 75mV shunt.
Power plant excitation system shunt
Power plant excitation system shunt
A shunt is a resistor that can pass a large current. Commonly used 15A, 20A, and 35A ammeters require a shunt. The impedance of the shunt is equal to the full voltage marked on the meter head divided by the full current on the meter head. For example, the shunt resistance of a 20A ammeter is 75mv/20A=0.00375 Ω. After the impedance is constant, according to Ohm's law U=IR, the current is proportional to the voltage, and the current is linear. Therefore, a voltmeter with a full scale of 75mv can be used to display the current. Therefore, the ammeter used is actually a voltmeter.
