100% Original MTL2316 BONDING INTEGRITY MONITOR With Good Price In Ready Stock

The MTL2316 continuously monitors a bonding conductor and warns of any significant change in resistance, or of a large current being conducted. The unit is designed for accurate monitoring of clean lowresistance (<1Ω) bonds located in hazardous areas or linked with intrinsically safe circuits and is ideally suited to monitoring ‘safety earths’ in barrier systems. Loop resistance (bond plus return lead) is monitored by means of a direct current of approximately 0.25mA so that no significant common-mode voltage is imposed on the bonded system.
