4B ADB Lug Temperature Sensor

         
 

The ADB Lug series is a surface mount style NTC thermistor, Platinum RTD (PT100), or 4-20 mA "Milli Temp" type of continuous temperature monitoring. It is designed to bolt directly onto a bearing housing, motor, gearbox, machine casing or any other application where surface temperature monitoring is needed.

 

The mounting hole is 3/8” from the factory, but can be drilled up to 1/2” if needed.  The sensor can be connected to a PLC or to a hazard monitoring system, such as 4B’s Watchdog Super Elite, IE-Node, T500 Hotbus or T400 Elite.

 

The connections are not polarity sensitive therefore special connections requirements are eliminated.
