XP12010 Explosion-proof Magnetic Pickup Sensor
Operation Manual

Model XP12010 pickup provides a sine wave output whenever
there is an abrupt change from non-magnetic to magnetic ma­terial moving past the sensor pole. The output voltage is direct­ly proportional to the change in magnetic flux intensity over the
change in time.

Specifically engineered for use in the oil and petrochemical in­dustries, this stainless steel sensor is completely sealed and ex­plosion-proof. Low impedance allows for transistor circuit input.
When mated with conduit, it provides positive protection against
damage due to water, high humidity, oil, dirt, or corrosive liquids.
ATEX listed for II 2 G Ex mb IIC T2 Gb. Explosion proof for gas,
vapor, and liquid. This magnetic sensor is a passive device and
no power supply shall be connected to it.

MOUNTING

The unit is designed to mount in a 3/4” -20 UN threaded hole and
provides a jam nut for securing the sensor.

ADJUSTMENTS

The pick-up should be adjusted for a typical clearance of

0.01” (0.25 mm) between the sensor and gear. This adjustment
will provide excellent sensitivity and resolution. Air gap between
the sensor and the exciter must be set so that the output does not
exceed 60 Vp for the maximum operating speed.

CONNECTIONS

The leads shall be terminated in a suitable certified enclosure or a
non-hazardous area. Polarity: White Lead is Positive with Respect
to Black Lead upon approach of ferrous metal.

OUTPUT

The output of the sensor is similar to the waveform in Figure 1.
The frequency of the signal is proportional to the speed. The am­plitude of the output signal increases with an increase in exciter
speed as shown in Figure 2. The output amplitude is also depen­dent on the sensing gap. At larger sensing distances, the ampli­tude is lower.
