Case Study 1A large chemical site fitted Crouse Hinds wireless units to its Emergency Showers to transmit activation alarms to the control center. If a lone plant operator or maintenance worker activates a shower because of chemical spillage, control center personnel are immediately alerted. The Crouse Hinds wireless units are battery powered to reduce total install costs, and form part of a larger wireless information backbone throughout the plant. The complete wireless network integrates a multitude of independent process applications into one wireless network, with multiple data bus and field bus connections. |
