to screw directly into an existing
grease zerk fitting on a bearing
housing. Each sensor is fitted with a
grease nipple to allow lubrication of
the bearing without the need for
removal of the sensor. The WDB
Series is available with either a PTC
manufacturers of thermistor with various factory set
trip points or an NTC thermistor
with a user adjustable trip point.
Other surface mount and adjustable
depth sensors are also available. The WDA Series are non-contactingextended range magnetic transducers
used to detect ferrous targets (such
as bucket bolts or steel industrial buckets) at
a distance of up to 100mm from the
sensor. Page 5-6 6 Touchswitch *Can be used with the Whirligig
universal shaft sensor mount The Touchswitch is an electro-
mechanical limit-switch style sensor
with no moving parts. It is designed to
detect belt tracking and misalignment
problems on bucket elevators and
suppliers of conveyors. Unlike a rub block that
utilizes friction (heat) to activate, the
Touchswitch is pressure sensitive for
safer and more reliable monitoring. page 1 0page 4

dangerous underspeed conditions.
An inductive sensing device located in
the nose of the enclosure will detect
a metal target. Set to the normal
machine RPM, 4B Speedswitches
provide alarm and shutdown signals
underspeed and stopped motion. 7 4B inductive proximity sensors suppliers are
designed to detect shaft speed, shaft
position, gate position, or object
presence. No contact is made
between the sensor and the target
being monitored. Sensors will detect
a ferrous object at Page 10 1 / 2 " and a non-ferrous metal object at a distance of 3 Binswitch 5 / 1 6 ". *Can be used with the Whirligiguniversal shaft sensor mount 1 0

page 8 The Binswitch detects level or plug
situations for bulk granular solids or
liquids in tanks, bins, or silos and can
be used as a plug or choke detector
in chutes, conveyors and industrial elevator legs. 8 Autoset Series Page 10 The Autoset Series are self-
contained point level monitors with
industrial digital displays for high, intermediate,
or low-level detection of liquids,
powders or free-flowing granular
solids. The Autoset Series incorporates
simple push-button calibration
with microprocessor enable/
disable switch for total
protection of stored values.
Once the unit is calibrated for a
specific application, it never
has to be re-calibrated. 4 Roto Level Series The Roto Level Series are rotary
paddle switches designed to detect
high and low levels of bulk granular
solids in bins, tanks, silos, and as
blockage industrial detectors in spouts. Page 10 1
