Chain-pull Transceiver -- 2

I need to make a device which will be used to read, transmit & store analog values from a device which will be powered by a small battery and ride along inside a conveyor chain link as it travels throughout its path in manufacturing plants. The entire device needs to fit in an enclosure approximately 500mm wide x 25 mm deep by 45 mm high. the strain gauge mounted in the inner portion of the chain link. The device would transmit the values via wi-fi or another radio signal and be received via a gateway and the values would be applied to an Excel file and translated to values in pounds of force. In the event communication is lost as the conveyor travels, values would be stored on board and then update the gateway when communication is restored and no information would be lost. The electronics would be inserted in a plastic enclosure for protection and a quick disconnect fitting would be used to connect and disconnect the strain gauge when the transceiver is removed frrom the conveyor system
