The latest NTC Watchdog Elite now incorporates continuous bearing temperature monitoring as well as fixed trip point monitoring. The system uses solid state NTC sensors or PTC sensors, allowing the user to set a temperature trip point and to monitor actual bearing temperatures in real time. Continuous temperature reading outputs can be monitored in any combination of up to 6 bearings, gearboxes, or machine surfaces.
As with our previous Watchdog Elite control units, you will also be able to monitor belt speed, belt and head pulley alignment, and plug condition on a single bucket elevator or belt conveyor. The LCD screen displays machine status (available in 4 different languages) and a super-bright LED display shows belt speed. It is easy to calibrate and setup using a simple front-panel touch button interface. The system includes alarm and shutdown contacts, RS485 output, and an optional PLC interface. Cert: ATEX/ IECEx Zones 21 & 22, & CSA
Indication of the current status is clearly visible on the W400 Elite control unit using bright LED’s. An alarm output is available through a volt free relay contact, and another relay contact is available for the stop condition. The W400 is equipped with a motor interlock so it can monitor directly the motor start/stop circuits ensuring a reliable response to the elevator signals. The W400 also has the facility to communicate to other systems using a RS485 communication interface.
