Feature

Connected to a special speed drum, can eliminate the usual tachometer friction between the wheel and the belt caused by the error caused by skidding. Speed sensor with 304 stainless steel shell, with good shielding, closed performance, suitable for outdoor installation.

Description

GTS gear speed sensor is an advanced speed sensor for non-contact detection of rotating body speed, Measuring range is 1 to 20000 rev / min, the output of the square wave signal can be directly and TTL, CMOS, etc.

Circuit interface, constitute the speed measurement / control system.GTS products using round pipe waterproof structure, with waterproof, dustproof, anti-oil advantages, can work reliably in harsh environments, especially for industrial control and military projects.

GTS speed sensor | speed switch instructions

1, the sensor dimensions shown in Figure 1, the installation of the sensor with the nut attached to the mounting hole, the fixed device recommended.

Non-magnetic materials (copper, stainless steel, etc.) sensors should be installed facing the tooth surface, the tooth surface and the sensor front face spacing should not be greater than the rated detection distance.

2, the detection gear can be the machine has been working gear or a dedicated gear, but should comply with the provisions of the three items should be

May use a smaller detection distance, the gear should also be used as much as possible high-permeability magnetic material modulus.

3, the actual speed range according to the number of gear teeth N and can be calculated by the following formula:

Speed range lower limit: Vmin = (rpm); Speed range upper limit: Vmax = (rpm)

5, in order to enhance the anti-interference ability of the signal, the sensor can adopt the electric current to output, and isolate with the photoelectric coupler on the receiving end.
