Wireless Intrinsically Safe Display

Requesting info on intrinsically safe wireless display for use inside a building, size of approx 100' by 200', I am looking for a portable display that via wireless link to a ControlLogix processor will continuously provide a readout of one process variable. Oh yes, the display unit will have to be rated for class 1 div 1 service. Any suggestions? I have a spare Modbus port available (from a Prosoft module) if that helps.
