WDB7 Series
Lug Style Surface Temperature Sensor
APPLICATION
For use on any application where surface temperature
monitoring is desired or required.
METHOD OF OPERATION
The WDB7 series is a lug style NTC thermistor or
platinum RTD (PT100) type for continuous temperature
monitoring. It is designed to bolt directly onto a bearing
housing, motor, gearbox, or machine casing. The
mounting hole is M8 which can be drilled out up to M10
diameter. The sensor can be connected to a PLC or to a
hazard monitoring system, such as 4B’s T500 Hotbus
Elite, Watchdog Elite, or T400 Elite. The connections
are not polarity sensitive therefore special connections
requirements are eliminated. The WDB7 series is
approved for use in ATEX and IECEx Zone 20 dust
