A400 Elite Trackswitch

Belt Alignment Monitor

The A400 Elite Trackswitch belt misalignment 

monitor uses 4B WDA magnetic proximity 

sensors to monitor the alignment of the belt in 

bucket elevators.  Each control unit incorporates 

two independent monitoring circuits for early 

detection of belt misalignment on one or two 

bucket elevators.

Watchdog™ Super Elite

Hazard Monitoring Control System

The Watchdog Super Elite is a microprocessor 

controlled unit with combined belt speed, belt 

alignment, bearing temperature, pulley alignment 

and plugged condition monitoring for bucket 

elevators and conveyors.  A 3.5” LCD screen 

displays the entire system status at a glance.

WDA High Temperature Sensor

(HTAS1V34)

Non-contacting extended range magnetic 

proximity sensor, not affected by dust or 

material build up, used to detect moving ferrous 

material up to 3 inches away from the sensor.  

Designed for temperatures ranging from 302° F 

(continuous) to 356° F (maximum).

Speed Relay

(SR2V5-1)

DIN rail mounted speed relay with a user 

adjustable underspeed relay contact output that 

can sound an alarm or shutdown machinery 

when the shaft speed falls below the preset level. 

WDA Sensor Mount

(WDAMB)

Plastic mount for the WDA sensor 

(included with sensor).
