N3xxC, hall sensors

N3xxC, hall sensors

Cylindrical rotation speed sensor based on the Hall effect with an electronic unit integrated into the sensor housing. Output: pulse signal 0...30 V, three-wire connection. Compatible with the installation locations of Braun sensors. The maximum operating temperature is up to +125°C.

The sensors consist of a measuring part (a sensitive magnetic element) in an externally threaded housing and a connecting cable. The sensors are connected using cable lugs or a sealed connector mounted on the connecting cable (depending on the design).

The output signal of the sensor is rectangular-shaped and constant-amplitude voltage pulses with a frequency of repetition of the tooth profiles of the control surface.

The sensor is not sensitive to radial shaft impacts.

1) The material of the control surface is ferromagnetic steel.
2) The optimal setting clearance value is selected depending on the size of the control surface and its shape (see the Application section).
3) The maximum temperature of the sensor's electrical connector (for versions with the "ST" code) is not more than +85 °C.
4) Us is the voltage level of the sensor supply; the voltage values are indicated at an output current of no more than 10 mA.

Application

Measuring the speed of rotation, direction of rotation and phase on the main and auxiliary equipment (shafts of steam, gas and hydraulic turbines, turbochargers, centrifugal pumps, Variable Drives ,Pumps , Fans , Conveyors , Generators , Gears , Motors ) with an ambient temperature of no more than +125 ° C.

The sensors can be used both independently to measure the speed of rotation, and as part of the automated control system measuring system.

1. For the groove control surface: the ratio of the dimensions of the control surface and the recommended sensor installation clearances:

Width (W), mm Depth (D), mm Thickness (T), mm Range of installation clearance, mm
not less than 3 not less than 3 not less than 5 from 0,5 to 1,50
not less than 4 not less than 4 not less than 6 from 0,8 to 2,00
not less than 5 not less than 5 not less than 7 from 0,9 to 2,50

2. For the gear control surface: if the number of slots (or teeth) is more than one, when selecting the sensor mounting gap, it is also necessary to take into account the gear module (M):

The gear module (M),*) Width (W), mm Range of installation clearance, mm
from 1 to 1,5 not less than 3 from 0,5 to 0,80
from 1,5 to 2 not less than 3 from 0,5 to 1,50
from 2 to 4 not less than 3 from 0,5 to 2,00
more 4 not less than 3 from 0,5 to 2,50
*) The gear module (M) is defined as the ratio of the outer diameter of the wheel, in millimeters, to the number of slots (teeth) according to the formula M = Di / N, where Di is the outer diameter of the gear (rotating profile),N is the number of slots (or teeth) of the gear.
