An apparatus for monitoring of transport containers

Abstract

A monitoring apparatus is for an internodal transport container. A proximity sensor is mounted to a door actuator and to a door or container panel. A tamper-evident local circuit with a processor detects relative movement of the actuator and the panel. A transmitter transmits an alert radiation signal with an alert of if there is movement of the actuator indicating opening of a container door or tampering with the apparatus. The sensor has a first component for mounting to an internodal container locking bar, and a second component part of the local circuit 10 for mounting to a door panel. The first component in some examples snap fits to the bar and has a rotatable component which is retained by a retainer attached to a housing which is in turn attached to a container door. There is therefore no need to attach anything to the bar.
