DC 8-24V Hall Tachometer Digital LED Motor Speed Meter Tester IP68 Waterproof

Feature:
1: 4-digits display, clear and easy for readings，Mini size, high performance and fast reaction speed.
2: With good stability, high accuracy, anti-interference ability.
3: IP68 waterproof grade is adopted to make the product more durable。
4: This product uses an anti-interference Hall switch, because the frequency converter on the device will interfere with
the detection of ordinary Hall switches. It is recommended to choose an anti-interference Hall switch to make the work more efficient.
5: Wide range of applications: such as the ship industry, outdoor wet, agricultural equipment, and windmills and waterwheels.

Note:
1. Connect the plug correctly according to the wiring diagram.
2. The Hall switch is NPN normally open type, and the detection distance of the Hall switch needs to be within 10MM. The Hall switch installation diameter is 12MM, and the wire length is 1M.
3. Strong electromagnetic interference should be avoided. It is better to use shielded wire or twisted pair for the measurement wire.
4. The count signal of the counter and the switch or circuit of the reset signal input should be as close as possible to the terminal of the counter, and the signal line should be as short as possible.
5. Avoid the same tube or twisted wiring with other such as: strong electric wire or power wire, etc., to avoid unnecessary interference, please use shielded wire if necessary, and the shielding layer is connected to the counting terminal "+".
6. It is not recommended to use mechanical switches or micro switches, because their lifespan is relatively short, and it is easy to miscount after a long time;
if you use mechanical switches or micro switches, please try to use better quality, so as to avoid miscounting, strong A magnetic switch is recommended.
